The 8 Best Dual Chamber PC Cases of 2025
An amazing case type for enthusiast builds: here are the best ones
We’ve updated this feature to cover 2025 releases. A couple of alternatives have been added, but most of our top picks remain the same this year.
What is a dual-chamber case anyway?
Let’s take some of the main criteria when looking for your perfect chassis:
- Plenty of space for hardware
- Good ventilation/airflow
- Stylish/made for showing off beautiful components.
A dual-chamber case excels at providing all of these things by essentially having a second “hidden area” for some of your less attractive parts.
Sure, most mid-range cases have some small cable management compartments.
But having a dedicated full chamber gives room for the other “ugly” parts. Think PSUs, hard drives, etc.
This then isolates your GPU/CPU in the “main” chamber, giving you a cleaner presentation and space/airflow for the parts that need it most.
They’re a fantastic innovation for PC builders, I’ve really enjoyed my time working in this format. Which is why I’ve put together this guide on the best PC cases with 2 chambers.

Best Dual Chamber PC Case: Lian Li PC-011 Dynamic
This really is a fantastic tower.
From one of the greatest chassis manufacturers today, the PC-011 Dynamic has been featured many times on What in Tech. It’s also my top choice for the overall best PC case in any category.
The PC-011 is beautiful. Boasting a very thick (0.8-1mm) SECC steel body, aluminum front, and dual-tempered glass layout.
The look and feel are simply fantastic for its price point. With the extra window on the front, you’ll have great visibility for your internal build.
Photos do not do it justice. I’ve built some nice setups in this case and seen many more. What gets me every time is how even something quite basic ends up looking stunning.

There’s plenty of room too, with:
- 8 expansion slots
- GPU cards of up to 420mm
- 2 x 3.5″ / 4 x 2.5″ drive bays (all hidden in the second chamber)
- Air cooling: Up to 9 x 120mm fans
- Or water cooling: Up to 1 x 360mm, 1 x 280mm & 1 x 240mm
These specs are great for the dimensions. The PC-011 is quite large with fantastic cooling capability.
With more room than our runner-up pick, it’s a good choice if you want to fit very large GPUs.
It’s officially a mid-tower case but would likely manage an E-ATX motherboard if that’s your goal (just check dimensions – we’ve got larger options below).
The second chamber on the PC-011 is wonderfully discrete and has room for all of the cable management and drives/PSUs we expect you’ll need in any kind of build, meaning you can establish a really neat main chamber with great airflow for your intensive hardware.
Speaking of power supplies, this is a great option if you’re after a dual PSU case. The hidden drive caddy in the second chamber can be removed for a second power supply.
Is there anything I don’t like about the case? Honestly…not really.
You could argue that in a feature focused on dual chambers, the second chamber is a little smaller than some of the other picks below. But I think this is a credit to the PC-011. It still includes enough space for PSUs, drives, and cables, without making the separate area look unnecessarily bulky or wasteful.
It is a little expensive. But really, it’s at the mid-range price point that many top-quality cases live in. You absolutely can go cheaper if you like, but I don’t fault the case’s price because I think the value on offer is great.
The fact that you’re getting such a wonderful build quality, aesthetic, space, cooling potential and a perfect internal layout to empower neatness/airflow all at a great mid-range price is simply incredible.
Yes, this is my pick for the best dual-chamber ATX case on the market, but to reiterate, it’s the chassis I think excels the most in any category, and frequently recommend it to my readers if you have the budget.
2025 update: The PC-011 remains our top dual chamber chassis pick for 5 years running! Despite some decent new offerings, nothing overtakes the great balance between features, aesthetics, and price. I also still rank it as the best overall case of the year.
Best Dual Chamber Case for Airflow: Corsair Series Air 540
The PC-O11 has fantastic airflow that we think will meet an overwhelming majority of needs.
But if you’re someone who really prefers taking advantage of mesh layouts that ensure ventilation from all angles, you may want to consider the Air 540.
This Corsair offering somehow manages to offer a fantastic set of features/quality while also being one of the cheaper options on the list
Boasting great space in both of its chambers, you’ll have room for:
- 8 expansion slots
- GPU lengths up to 320mm
- Up to 2 x 5.25″, 2 x 3.5″ and/or 6 x 2.5″ drives, more than enough for gamers
It’s nice to see options for optical drive bays here too (even though a majority of people no longer use them, you can still convert 5.25″ bays into more SSD/HDD drive bays if desired).

But it’s cooling where a dual-chamber tower really shines. In the Air 540’s case, there’s space for:
- 6 x 120mm / 5 x 140mm fans (including 2 pre-installed Corsair Air Series AF140L fans ideal for a quiet build)
- 280mm top & 360mm front radiators
Now that may not sound too impressive for an ATX case.
But remember: with your PSU/drives out of the way, these fans/water coolers are dedicated to cooling your GPU and CPU.
Tie that with the fantastic airflow design and you have a really high-value case for overclocking.
Style-wise, the Air 540 has a unique wide form factor.
With a steel exterior, the cube tower boasts a simplistic, high-quality build. In person, it appears minimalist and monolithic.
This simplicity is perfect because when you’re creating a dual-chamber computer, you want the attention to be on the neat internal parts in the main chamber.
Through its tempered glass, the case beautifully presents the main hardware and gives you more than enough space to cleanly build.
We love the PC-O11D and made it our top choice for a reason. But if you’re looking for something that balances unique style, fantastic features, cooling capability, and value; the Air 540 is also well worth considering.
Best High-End Dual Chamber Case: Corsair Crystal Series 680X
Having been featured multiple times previously on What in Tech, there are so many amazing qualities to the 680X if you can afford its price tag.
The 680X has some of the best build quality I’ve seen in any case.
With a thick steel exterior, and tempered glass covering its front, top, and hinged side window, the case looks incredible even before you add your hardware.
The RGB version we recommend includes 3 beautiful & addressable Corsair LL120 fans which are some of the best on the market and very expensive if bought solo.
Alongside these is a pre-installed Corsair Lighting Node Pro. One of the best RGB controllers available today, making this a perfect base for an RGB build.
The 2 chamber case offers good internal space too. With:
- 10 expansion slots (2 for a vertical GPU mount)
- GPUs up to 330mm
- 3 x 3.5″ & 4 x 2.5″ drive bays (hidden in second chamber)
The GPU length may seem low compared to the Lian Li, but it’s still more than enough for nearly all mainstream cards. There are also enough storage options if you’re looking for a video editing or server PC case.

What’s even more impressive is the cooling potential:
- Up to 8 120mm fans
- 360mm front, 280mm top, 140mm rear & 280mm bottom radiator support
Bearing in mind this is all part of a case with a large secondary chamber where you’re already maximizing airflow to your GPUs/CPU.
Adding this incredible cooling utility on top makes this one of the best ATX cases for overclocking. I’ve been super pleased with the thermal benchmarks from the case during test builds.
Yes, it is pricey.
But you’re getting so much for your money.
From the excellent build quality to the RGB capability, to the fantastic space and airflow design.
If you have the budget, it’s one of the best premium cases available (not just in the dual-chamber category).
Best Dual Chamber Micro ATX Case: Corsair Crystal Series 280X
What about those looking for a small PC case?
Well, thankfully, Corsair’s fantastic 680X has a little brother.
And despite the lower price-point/size, it still manages to retain so much of what makes the ATX version great.
The design is essentially the same (but more of a cube shape) with the high-quality steel exterior and triple-tempered glass setup.
The space is great for its Micro ATX form factor, with:
- 4 expansion slots
- VGAs up to 300mm
- 2 x 3.5″ & 3 x 2.5″ drive bays hidden in the second chamber
Source: PTjutsu
I would’ve liked to have seen an extra 5-10mm clearance for GPUs, but you should still manage to fit most cards (just please check dimensions before buying your card!).
The dual-chamber is still (impressively) large enough to hide your cables, PSU, and drives despite the smaller case size.
Between the room and cooling, the 280x is a fantastic case for Micro ATX gaming, with:
- Up to 6 120mm fans
- 1 x 280mm top & 2 x 240mm front/bottom radiators
Most in this form factor will not perform as well for cooling & overclocking your GPU/s.
It’s pricey for a smaller build, but I think it’s a great example of getting what you pay for.
I’d also argue with the 2 included RGB fans/Lighting Node controller, the price is actually very decent.
If you’re building a mini-tower and want an RGB aesthetic, you really can’t get much better (or more stylish) than the 280X.
Best Dual Chamber EATX Case: Thermaltake Tower 900
So what if you’re less constrained by budget and want something extra large and powerful?
Whether for a high-end gaming build, production rig, or server PC, an E-ATX case is a great option.
If you combine such a huge size with a dual-chamber layout, you’ve got some real monstrous capability.
The Tower 900 is one of the best examples, with:
- 8 expansion slots
- GPUs up to 400mm (including vertical mount option)
- Up to 1 x 5.25″, 6 x 2.5″/3.5″ & 2 x 2.5″ drives
You have room in this huge case to host a quad-GPU build if tied with an accommodating motherboard.
The case also offers the most cooling on the list and some of the most out of any Extended-ATX case we’ve seen, with:
- Up to 13 x 120mm fans
- 1 x 480mm & 1 x 560mm radiators
The radiators are installed on the left and right sides, meaning if you wanted to make a liquid/air cooling hybrid, you could also still include 5 x 120mm fans.

As you can imagine, between this cooling and the very spacious dual chamber, you have one of the best water cooling cases in the Tower 900.
Another factor it excels in is the modularity/customization available.
This means that so much of what is included (anything from drive bays to dust filters) is completely detachable.
Minimizing parts you don’t need will give you more space for parts/airflow, a cleaner presentation, and reduce vibration (great for a quiet PC build).
Last but by no means least is the design and quality.
Rivaled on this list only by the 680x, the Tower 900 looks and feels fantastic.
With an SGCC steel exterior and 3 full-size windows, it’s somewhere in-between a tempered glass chassis and a sturdy fish tank!
Needless to say, it looks fantastic displaying your main components while the dual-chamber is more than enough to hide what you don’t want to show.
It was really a toss-up between this and the Corsair 680X for the best high-end pick.
The reason we gave it to 680X is that an E-ATX case can be a little too large for many builders and I think the Corsair ATX offering has what most of you would need.
But if you’re drawn to the Tower 900’s monumental capability, or simply want the most powerful dual-chamber computer case you can possibly find, then you can’t go wrong here.
2025 update: If you like the look of the Tower 900 but don’t necessarily need something quite so monolithic, Thermaltake has released the Tower 500, which includes a similar build quality and feature set to the 900 (including EATX motherboard capacity) within some smaller mid-tower dimensions.
Worth Considering: Thermaltake Level 20 HT
Last but by no means least.
While not getting one of our top dual-chamber chassis picks, we’ve included the 20 HT for a reason.
You’ll notice it’s similar to our above Thermaltake EATX choice.
When considering the Level 20 HT vs Tower 900, this case seems to be, in many ways, a slightly smaller version of the 900.
That’s not to say it doesn’t have a ton of room for your parts though, with:
- 8 Expansion slots
- VGA length up to 400mm
- 4 x 3.5″ / 2.5″ & 1 x 2.5″ drive bays
It’s still very much a great fit for a large gaming chassis, with enough room for plenty of GPUs and an ATX/EATX build.

The same can be said for the cooling, with space for:
- Up to 10 x 120mm fans – 2 high-quality 140mm fans are included
- 2 x 360mm & 1 x 280mm radiators
So there’s slightly less space capability compared to the Tower 900. But let’s be real; that’s still a lot of air/water cooling potential.
Not to mention your PSU/drives/cables are suitably hidden in the spacious second chamber.
This is still most definitely an overclocking-capable choice ideal for gamers/multi-GPU builds.
The build quality is as fantastic as you’d expect for a high-end Thermaltake case.
With an SPCC steel exterior and thick tempered glass windows surrounding the left, right, and front. A nice touch is the addition of a glass panel to the top of the chassis, it’s a clear PC case made to show off your hardware.
With the included fans and the slightly lower price point than the Tower 900, we’ve included this as it’s a great option for someone who likes the look of the 900, but doesn’t need quite the space and wanted to save a little money.
Quick-Fire Picks
While the top 6 are the best dual-chamber cases for a large majority of users, we wanted to throw in another couple of worthy considerations if your needs are more specific.
Cheapest Dual Chamber PC Case: Rosewill CULLINAN PX
While we consider the top 2 options cheap dual chamber pc cases for what you’re getting, this Rosewill offering is the cheapest available that we could still recommend (and impressively includes 3 fans).
You won’t get the same build quality, cooling, or feature set, but as far as budget options go, this is a great pick.
Best RGB Dual Chamber Case: Anidees AI Crystal Cube
A great case in its own right (especially for RGB lovers), the Anidees Crystal Cube is perfect for someone after a unique aesthetic.
A little more expensive and from a lesser-known manufacturer than our top picks, but you are also getting 5 addressable RGB fans and 2 RGB headers. So if you’re more focused on aesthetics, this isn’t a bad option at all.
Best Dual Chamber ITX Case?
You may have noticed we haven’t included a Mini ITX dual-chamber PC case.
Unfortunately, there isn’t one on the market that we’d recommend for enthusiast builds.
Your best option to get the best out of a dual-chamber gaming PC case is the Corsair 280X discussed above.
This case still has a great small form factor and is light enough that is can act as a portable PC case/perfect for an on-desk setup.
Remember that although it’s a Micro ATX case, you can still fit a Mini-ITX motherboard on it if that’s how you want to build.
You may also appreciate the smaller version of our top pick, the O11D Mini-X. While technically still an ATX case, it has an impressively tight form factor, an ITX build would operate great inside.
2025 update: The Lian Li O11 AIR MINI has entered the market and is another excellent option. Like the 011D Mini-X, it’s ATX case, but its dimensions feel closer to a smaller form factor and would be great for a more portably-inclined build.
