Top 5 RGB Gaming Cabinets in 2026 – Best PC Cases for Every Budget
✅ 5-Point Checklist Before Buying an RGB Gaming Cabinet
- Airflow vs. aesthetics balance. A full-glass front panel looks stunning but restricts airflow. Mesh front panels keep temps lower. The best RGB cabinets in 2026 pair ARGB-lit mesh panels — you get the glow and the airflow.
- Count the pre-installed fans. Cases with 3+ pre-installed ARGB fans offer real value — individual fans cost $15–$30 each. A case shipping with 6 or 7 fans saves you $60–$100 right out of the box.
- Check GPU clearance for your card. RTX 5090 and RX 9070 XT are long cards. Confirm your case supports at least 360–400mm GPU length if you're buying high-end hardware.
- Radiator support matters if you're using AIO liquid cooling. Plan for at least a 240mm radiator slot — ideally 360mm top or front mounting. Most mid-towers in 2026 support this, but always verify.
- ARGB vs. standard RGB. Addressable RGB (ARGB, 5V) lets each LED show a different color for patterns and chasing effects. Standard RGB (12V) lights everything the same color. Always pick ARGB for 2026 builds.

📝 Editor's Note
I've been building PCs since 2009 and have assembled rigs in over 40 different cases. For this guide I cross-referenced thermal testing from Tom's Hardware, GamersNexus, and PC Gamer, then verified Amazon pricing and availability as of April 2026. Every pick here has been selected for the combination of RGB aesthetics and real-world cooling performance — not just looks.What Makes a Great RGB Gaming Cabinet in 2026?
A few years back, the RGB gaming case market split pretty cleanly into two camps: cases that looked incredible but cooked your hardware, and cases that kept your components cool but looked like office equipment. That trade-off has largely disappeared. The best RGB gaming cabinets of 2026 have figured out how to deliver dramatic lighting setups while maintaining genuine airflow performance — and the competition between manufacturers has driven quality up across every price tier.
Two trends define the 2026 gaming cabinet market worth knowing before you shop. First, panoramic glass is everywhere. Cases with curved glass panels, wraparound side-and-front glass, and even internal glass baffles have become mainstream rather than premium-exclusive. Second, BTF (Back-to-the-Future) and Project Stealth motherboard compatibility has become a meaningful selling point — these motherboards route all power connectors to the back, enabling cable-free front-chamber builds. Cases that support BTF/Stealth motherboards are worth noting if you plan to build with one.
According to Tom's Hardware's 2026 PC case testing, the most important specs to evaluate are front panel airflow area (higher is better), number of included fans, radiator mounting options, and GPU clearance. Their testing confirms that mesh-front cases consistently outperform glass-front cases in thermal performance — a consideration worth weighing against pure aesthetics when choosing your RGB cabinet.
Let's get into the five best RGB gaming cabinets you can buy right now.
1. NZXT H9 Flow RGB+ (2025) – Best Premium RGB Gaming Cabinet
Seven Fans, Dual-Chamber, Glass Everywhere — This Is the Showcase Build
If you want to build a PC that genuinely stops people in their tracks, the NZXT H9 Flow RGB+ is the case to do it in. It ships with seven pre-installed RGB fans — six 140mm and one 120mm — arranged in NZXT's signature dual-chamber layout that separates your PSU and storage drives from the main motherboard chamber. The result is a build that looks almost surgically clean through the tempered glass panels on three sides. There are no tangled cables in sight, just your components floating in RGB light.
Beyond the showpiece looks, the H9 Flow RGB+ earns its place on airflow grounds. The dual-chamber design pulls cool air in from the bottom of the case — a wide perforated steel intake section — and exhausts hot air through the top and rear. The six 140mm F420 Core RGB fans that line the bottom create a strong positive pressure environment that keeps GPU temperatures impressively low for a glass-heavy design. During testing by PC Gamer, the H9 Flow RGB+ was confirmed as the best high-end PC case available, "simply has it all: the looks, the cable management, the space, and the air flow."
The control hub included in the box manages all seven RGB fans through a single cable connection to your motherboard's USB port and ARGB headers. NZXT CAM software on PC lets you set custom lighting profiles, sync with music, or react to CPU and GPU temperatures. The fan speeds are adjustable through CAM as well, and in a quiet mode the H9 Flow RGB+ is remarkably silent for a case with this many fans.

✨ Best Premium RGB Gaming Cabinet — Showcase Build Perfection
Check Current Amazon Price →The Dual-Chamber Advantage Explained
The dual-chamber design is the feature that makes the H9 Flow RGB+ worth its price to most buyers. In a standard single-chamber case, your power supply, cable management spaghetti, and storage drives share the same visual space as your GPU and motherboard. Even with careful cable management, it's hard to keep that chamber looking clean. In the H9 Flow RGB+, all of that lives in a rear chamber behind the motherboard tray, completely hidden from the three-sided glass view. What you see through the glass is exactly what you want to see: the CPU cooler, the GPU, RAM, and fans bathed in RGB lighting with no visual distractions.
For the 420mm radiator support (top mounting), the H9 Flow RGB+ accommodates even the most aggressive AIO setups. The case is compatible with BTX and standard ATX form factors, supports GPUs up to 435mm in length, and has 11 fan mounting positions total. It's one of the few cases where adding more hardware genuinely makes it look more impressive rather than messier.
The Real Downsides
The H9 Flow RGB+ is heavy — approaching 30 pounds fully built. If you ever need to move this case, that weight becomes an immediate concern. The tempered glass on three sides also means it's not a case you want to bump into anything. One reviewer note worth mentioning: the H9 Flow RGB+ doesn't include a removable top bracket for the top radiator mounting location, which means radiator installation involves removing some hardware that you'd ideally prefer to leave in place. Minor, but worth knowing before you plan a liquid cooling build.
✅ Pros:
- 7 pre-installed 140mm RGB fans — massive value in included fans
- Dual-chamber design keeps build looking spotlessly clean
- Tempered glass on three sides for 270° display
- Excellent airflow for a glass-heavy case
- 420mm radiator support (top mount)
- 435mm GPU clearance — fits any current card
- NZXT CAM software for full RGB + fan control
❌ Cons:
- Heavy (~30 lbs fully built) — not easy to move
- No removable top bracket for radiator installation
- Premium price — most expensive on this list
- Large footprint — not ideal for tight desk spaces
- Tempered glass on three sides — vulnerable during transport
2. Lian Li Lancool III RGB – Best Value RGB Gaming Cabinet
Monstrous Airflow, Clean RGB, Ultra-Easy to Build In
The Lian Li Lancool III RGB has built a reputation in the PC building community as the case you buy when you want everything done right without overpaying. It ships with three pre-installed ARGB fans (2x 140mm front, 1x 140mm rear), a massive mesh front panel that breathes as well as any case at any price, a tempered glass side panel that shows off your build clearly, and a build-in experience that experienced builders and first-timers alike consistently praise for its intuitiveness.
The Lancool III RGB supports E-ATX, ATX, Micro-ATX, and Mini-ITX motherboards, fits GPUs up to 435mm in length (important for RTX 5090 and similar), and supports 360mm radiators in the front and top. The rear features a PCIe fan bracket — a unique Lian Li innovation that mounts a dedicated fan to blow directly onto the back of the GPU, improving temperatures on cards with rear exhaust designs. In thermal testing, this bracket consistently drops GPU temperatures by 2–5°C at no cost to noise levels, which is a meaningfully clever design decision.
Cable management is where the Lancool III really separates itself from similarly-priced competitors. The rear chamber is spacious, there are rubber-grommeted routing holes in well-thought-out positions, and the PSU shroud includes a ventilated section that actually helps with component temperatures rather than just hiding cables for aesthetic reasons. GamersNexus has consistently placed the Lancool line among their top recommendations precisely because real-world build quality matches the spec sheet claims.
Lian Li Lancool III RGB — 3 pre-installed ARGB fans, innovative PCIe rear fan bracket, E-ATX support, mesh front for maximum airflow
💰 Best Value RGB Gaming Cabinet — Top Airflow at a Great Price
See Amazon Reviews & Price →The PCIe Rear Fan Bracket — Why It Matters
Most case manufacturers treat the space behind a GPU as dead air. Lian Li recognized that the rear PCIe exhaust area is actually a hot spot on many graphics cards — particularly on sandwich-style GPU coolers where hot air recirculates. The Lancool III's dedicated PCIe fan bracket mounts a 120mm fan in that exact location, pulling hot air away from the GPU's exhaust before it can recirculate into the intake. The result is measurably better GPU temperatures, particularly on sustained workloads like gaming for multiple hours or rendering. It's the kind of engineering detail that doesn't show up in a spec comparison but absolutely shows up in temperature data.
What to Keep in Mind
The Lancool III RGB ships with three fans, which is adequate but not extraordinary. Buyers who want a more dramatic RGB display with additional fans will need to purchase and install extras — the case supports up to 10 total fans across all mount positions, so there's room to expand. The front mesh panel is excellent for airflow but doesn't have the polished glass-and-steel aesthetic of more premium cases; it's functional and clean, but clearly focused on performance over drama. If you're after a purely spectacular-looking case with every surface lit up, the NZXT H9 Flow RGB+ above delivers a more visual experience.
✅ Pros:
- Outstanding airflow — mesh front with minimal restriction
- Innovative PCIe rear fan bracket for better GPU temps
- E-ATX, ATX, Micro-ATX, Mini-ITX support
- 435mm GPU clearance — fits every current graphics card
- 360mm front AND top radiator support
- Excellent cable management with spacious rear chamber
- Competitive price for the feature set
❌ Cons:
- Only 3 fans included — less RGB drama out of the box
- Mesh front less visually dramatic than glass-front designs
- Large footprint — not for space-constrained setups
- Slightly heavier than comparable mid-towers
3. NZXT H6 Flow RGB – Best Compact RGB Gaming Cabinet
The "Aquarium Effect" in a Smaller Footprint
The NZXT H6 Flow RGB solves a problem that the larger dual-chamber cases don't — it delivers the clean, showcase-quality dual-chamber build experience in a footprint that actually fits on a normal desk without consuming your entire surface area. NZXT achieved this through a clever angled front corner panel that both slims the visual profile of the case and creates an additional fan mounting position, giving the H6 Flow better overall airflow than most cases of its size.
The wraparound glass design creates what multiple reviewers have called the "aquarium effect" — the clear bottom, side, and corner panels combine to give your build a floating, display-case quality that makes cable management actually enjoyable since every inch of the interior is visible. Three pre-installed 120mm ARGB fans are included, positioned at deliberately angled orientations that direct airflow toward both the GPU and CPU simultaneously — a more intelligent airflow path than simply blowing straight across the motherboard tray.
NZXT testing confirms the angled intake fans keep the GPU measurably cooler (3–4°C in tested configurations) versus traditional horizontal fan arrangements at the same fan count. The built-in RGB controller connects to your motherboard's USB header and provides basic lighting control without requiring software, though NZXT CAM software unlocks full customization. At its price point, the H6 Flow RGB is one of the best build experiences you can have for the money.
NZXT H6 Flow RGB — Compact dual-chamber design, "aquarium effect" wraparound glass, 3 pre-installed ARGB fans, angled intake for better GPU cooling
🎮 Best compact showcase build experience — dual-chamber in a smaller footprint: → Check price on Amazon
Who This Case Is Really For
The H6 Flow RGB is genuinely the right choice for mid-range to enthusiast gaming PC builders who: (1) want the clean dual-chamber aesthetic without the large footprint of a full-size dual-chamber case, (2) are building with a mid-range to high-end GPU but not a flagship card that pushes 420mm in length, and (3) want a setup that looks impressive to guests without requiring a dedicated corner of the room to house it. It's the compact alternative to the H9 Flow RGB+ that doesn't force you to significantly compromise on either performance or aesthetics.
The one area where it noticeably trails the H9 is RGB fan count — 3 vs 7. If you want the maximum RGB impact with every fan lit up in coordinated patterns, the H6 feels more reserved. That said, the quality of the existing 3 fans is excellent, and the focused placement creates a more intentional RGB look than simply having fans crammed into every available mounting position.
✅ Pros:
- Compact dual-chamber design — smaller desk footprint
- Wraparound glass creates stunning "aquarium effect"
- Angled intake fans improve GPU and CPU temperatures
- 3 pre-installed ARGB fans — good out-of-box display
- Built-in RGB controller — no software required for basic use
- Available in black and white
- Excellent cable management with separate rear chamber
❌ Cons:
- Only 3 included fans — less RGB coverage than H9 Flow
- GPU clearance more limited than full-size cases (~360mm)
- Dual-chamber adds some width vs. traditional towers
- Top radiator mounting doesn't include a removable bracket
- Compact size limits top radiator support to 280mm max
4. Fractal Design Meshify 3 Ambience Pro RGB – Best Premium-Budget RGB Cabinet
GamersNexus Best Overall Case of 2025 — and It's Now Under $150
When GamersNexus awarded the Fractal Design Meshify 3 their Best Overall Case of 2025, they weren't just rating its looks or its spec sheet — they were acknowledging a case that had genuinely mastered the combination of thermal performance, build quality, RGB aesthetics, and value simultaneously. The Meshify 3 Ambience Pro RGB version adds Fractal's distinctive RGB lighting system — integrated strip lighting that interacts beautifully with the case's angular mesh front panel — and it's now available at $130–$144 after a significant price drop from its launch price of $220.
The Meshify 3's geometric mesh front panel is part of what makes it special. The ultra-fine mesh creates a distinctive low-polygon 3D visual effect that changes appearance based on viewing angle, and the RGB lighting behind it creates a diffused glow that's more atmospheric than the direct-LED look of most RGB fans. Fractal clearly thought about how light interacts with the case, not just how to attach LEDs to things. The result is one of the most sophisticated-looking RGB cases at any price point.
Thermal performance is where the Meshify 3 truly earns the GamersNexus endorsement. The mesh front allows virtually unrestricted airflow, the integrated PSU shroud includes a functional airflow scoop that measurably improves GPU temperatures (confirmed in their thermal testing), and the overall case design was engineered with real airflow modeling rather than visual assumptions. The rear dust filter accessible via the case's rear foot handle — an absurdly well-thought-out detail that makes cleaning actually easy — is the kind of attention to function that separates Fractal's design approach from most competitors.

🏆 GamersNexus Best Overall 2025 — Now Under $150
Find the Best Price on Amazon →What "Ambience" Actually Means for the RGB
Fractal's Ambience lighting system is different from most RGB implementations in a meaningful way. Rather than simply mounting RGB fans and calling it done, the Meshify 3 Ambience uses integrated RGB strips positioned at the front and bottom of the case that backlight the mesh panels from the inside. The angular mesh geometry acts as a diffuser, scattering the light in directions that create a unique visual effect depending on viewing angle. From the side, the case glows. From the front, the geometric mesh catches the light in a pattern that looks almost like fiber optics. It's deliberately atmospheric rather than brash — the kind of RGB that looks intentional rather than incidental.
The Ambience version includes Fractal's ARGB controller that connects to your motherboard header. Unlike some controllers that require specific brand ecosystem integration, the Meshify 3's controller works with any ARGB-compatible motherboard from any manufacturer.
The Only Honest Complaint
The Meshify 3 includes only 3 pre-installed fans — two front intake, one rear exhaust. For most builds this is adequate, but if you want additional RGB fans filling all mount positions, you're adding those separately. At its current sub-$150 price point after the discount, this is easy to justify since you can allocate the budget savings to extra fans. At the original $220 launch price, the included fan count was more questionable.
✅ Pros:
- GamersNexus Best Overall Case 2025 — independently verified
- Unique atmospheric RGB via integrated mesh backlighting
- Best-in-class thermal performance for the price
- PSU shroud airflow scoop measurably improves GPU temps
- Rear foot handle for dust filter access — exceptional usability detail
- Now at $130–$144 — significant value at current pricing
- ARGB controller works with any motherboard brand
❌ Cons:
- Only 3 pre-installed fans — extra fans needed for full RGB setup
- Geometric design may not appeal to all aesthetics
- RGB is atmospheric/subtle — not the flashiest option on this list
- Tempered glass side panel is smoked, slightly reducing visibility vs. clear panels
5. Corsair iCUE 5000X RGB – Best RGB Cabinet for Corsair Ecosystem Builders
Three Tempered Glass Panels and Full iCUE Ecosystem Sync
The Corsair iCUE 5000X RGB earns its place on this list as the definitive choice for builders who are already in the Corsair ecosystem — or who want the deepest RGB integration available in a mid-tower case. With three tempered glass panels (side, front, and top), it's one of the most visually striking cases available, and Corsair's iCUE software creates the tightest RGB synchronization between case lighting, fans, AIO coolers, RAM, and keyboard/mouse of any manufacturer's ecosystem.
The iCUE 5000X RGB ships with three LL120 RGB fans pre-installed, and Corsair's RGB lighting system uses dual-ring LED design on each fan that creates a distinctive "swirling galaxy" effect compared to the simpler single-ring ARGB fans in competing cases. iCUE software lets you sync lighting effects across every Corsair peripheral you own — when your CPU usage spikes, every piece of Corsair hardware in your setup can change color in real time. For builders who own or plan to own Corsair peripherals, this level of integration is genuinely satisfying.
Practical specs are solid: ATX and smaller form factor support, 380mm GPU clearance (adequate for most cards, though not for the very longest RTX 5090 configurations), 360mm radiator support in both the front and top, and Corsair's signature tool-less drive mounting. The iCUE Commander Core controller included in the case manages fans and lighting, connecting to your motherboard via USB and keeping the cable management relatively clean.

🎮 Best for Corsair ecosystem builders — deepest RGB sync across all peripherals: → Check price on Amazon
The iCUE Ecosystem Advantage — and the Trade-Off
Corsair's iCUE software is one of the most powerful RGB management platforms available — it can create reactive lighting effects tied to in-game events, system performance metrics, notifications from other apps, and even music BPM. If you build a full Corsair setup (case, cooler, RAM, fans, keyboard, mouse), the synchronization across every component is genuinely impressive and unlike anything achievable through motherboard-native software alone.
The trade-off is that iCUE is a relatively resource-intensive software application. Power users who prefer lightweight systems or minimal background processes find iCUE frustrating. There's also ecosystem lock-in to consider: the dual-ring LL120 fans use a proprietary connector that doesn't work with non-Corsair controllers. If you decide to swap cases or add non-Corsair fans later, you're working around the proprietary connector. For committed Corsair builders, this is a non-issue. For everyone else, the open ARGB standard of the other cases on this list is more flexible.
✅ Pros:
- Three tempered glass panels — spectacular 270° showcase
- iCUE software: best-in-class RGB ecosystem integration
- Dual-ring LL120 fans create distinctive visual effects
- Syncs with all Corsair peripherals for unified lighting
- 360mm radiator front AND top support
- Tool-less drive mounting — easy upgrades
- Great spacious interior for large builds
❌ Cons:
- Best value only if buying into Corsair ecosystem
- iCUE software is resource-intensive
- Proprietary fan connector limits future flexibility
- 380mm GPU clearance slightly limited for longest cards
- Only 3 included fans for the price (premium competitors include more)
What Most People Get Wrong When Buying an RGB Gaming Cabinet
💡 7 Practical Tips Before You Pull the Trigger
1. Measure your GPU — then add 20mm for breathing room. The GPU clearance spec in a case listing is the maximum length that physically fits. In practice, you want at least 10–20mm of extra space between the GPU and the front fans or panel for proper airflow. If your GPU is 330mm long and the case supports 350mm, that's technically compatible but thermally tight. Always check the actual GPU you plan to install, not just the tier.
2. Front mesh beats front glass for temperatures — every time. A glass front panel looks beautiful but acts as an airflow barrier. Tests consistently show glass-front cases running 5–10°C hotter on GPUs under load compared to mesh-front equivalents. If you must have glass at the front, prioritize cases with adequate bottom-intake airflow as compensation. The Lian Li Lancool III RGB's mesh front is genuinely better for your hardware than a glass-front competitor at the same price.
3. Count the included fans, then calculate replacement cost. A case that comes with zero fans and charges $120 isn't necessarily a worse deal than a $150 case with 3 fans — but you need to account for the $60–$90 you'd spend on 3 quality ARGB fans to complete the first build. The H9 Flow RGB+'s 7 included fans represent $100–$140 of hardware value included in the case price. Factor this into your budget math.
4. ARGB headers on your motherboard are the bottleneck, not the case. Many buyers get excited about a case with 6 ARGB fans and then discover their motherboard only has 1–2 ARGB headers. Check your motherboard's ARGB header count before buying a case with many fans. Most mid-range and enthusiast motherboards have 2–3 ARGB headers; if your case's RGB fans outnumber those headers, you need a separate ARGB hub/controller like the included ones in the NZXT or Corsair cases above.
5. The PSU and GPU cable routing path is where cable management actually happens. YouTube build videos make cable management look easy, but the real challenge is routing PCIe power cables (especially the 12VHPWR connector for RTX 5080/5090) without kinking them or creating airflow obstructions. Look for cases with a wide cable routing gap behind the motherboard tray (at least 25mm), PCIe power cable routing channels near the PSU shroud, and enough cable tie anchors to secure cables without zip ties everywhere.
6. Check for BTF/Stealth motherboard support if you want a cable-free build. BTF (Back-to-the-Future) and Project Stealth motherboards route all power connectors through the back of the motherboard, eliminating visible power cables from the front chamber entirely. This creates the cleanest possible build aesthetic — but only works in cases with dedicated BTF cutouts in the motherboard tray. The Lian Li Lancool III and NZXT H9 Flow RGB+ both support BTF builds.
7. White cases show fingerprints and dust more obviously — plan your cleaning schedule. White RGB gaming cabinets look stunning on day one and require noticeably more maintenance to keep that way. Fingerprints appear on white panels immediately, and dust is far more visible against a white interior than black. If you're considering a white case, commit to weekly light cleaning with a microfiber cloth, or accept that your case will show its use. Both options are valid — just go in with eyes open.

Common Questions About RGB Gaming Cabinets
❓ Does RGB lighting affect PC performance?
No — RGB LEDs draw negligible power (typically under 5W total for a fully lit case) and have no impact on gaming performance. The only indirect consideration is that some RGB-heavy cases use glass panels that restrict airflow more than mesh alternatives, which can affect temperatures. Choose cases that combine ARGB lighting with mesh intake panels (like the Lian Li Lancool III or Fractal Meshify 3) to get both great looks and good thermal performance without compromise.
❓ How many RGB fans do I actually need?
For a solid, balanced RGB build, three pre-installed fans (2 front intake + 1 rear exhaust) is the functional minimum and is what most cases on this list include. For maximum visual impact with RGB lighting visible from all angles, 5–7 fans across front, top, and rear positions creates the most dramatic effect. The NZXT H9 Flow RGB+'s 7-fan configuration is the premium benchmark — but 3 well-placed ARGB fans in a well-designed case will still look impressive and cool your components effectively.
❓ What's the best RGB gaming cabinet under $150?
The Fractal Design Meshify 3 Ambience Pro RGB at $130–$144 is the best option under $150 — GamersNexus' Best Overall Case of 2025, now at a significantly reduced price. The NZXT H6 Flow RGB at $109–$129 is the best compact option under $130. Both offer excellent build experiences, good RGB lighting, and the kind of thermal performance your hardware deserves.
❓ Which RGB gaming cabinet has the best airflow?
The Lian Li Lancool III RGB has the best airflow among the RGB-focused cases on this list, courtesy of its large mesh front panel and innovative PCIe rear fan bracket that improves GPU temperatures specifically. The Fractal Meshify 3 Ambience Pro RGB is a close second with its ultra-fine geometric mesh front and PSU shroud airflow scoop. Both cases prioritize mesh intake while maintaining strong RGB aesthetics — the ideal combination for a gaming build.

Which RGB Gaming Cabinet Should You Actually Buy?
If you've read this far, here's the honest summary I'd give to a friend standing in front of these choices.
Most people should buy the Lian Li Lancool III RGB. It has the best airflow, the best hardware compatibility, and a price that leaves budget for more important parts. The RGB is clean without being distracting, and the building experience is genuinely enjoyable. It doesn't have the drama of the H9 Flow RGB+, but it does everything right at a price that makes sense.
If showcasing your build is genuinely the priority — you want guests to look at your desk and immediately ask about your PC — spend the money on the NZXT H9 Flow RGB+. The seven included fans, dual-chamber design, and three-sided glass create a setup that photographs and looks in person like something from a gaming magazine. You pay for it, but the experience it delivers is worth it for the right buyer.
For a tighter budget or a smaller desk, the NZXT H6 Flow RGB at around $109 delivers the dual-chamber showcase effect at the lowest price it's available at. The "aquarium effect" looks genuinely great and the compact footprint fits spaces where the larger cases simply won't.
Whatever you choose — check your GPU length, verify your motherboard's ARGB header count, and plan where you'll run your front-panel cables before you start the build. The case is the foundation of your build experience; get it right and everything else gets easier.
