Introduction
The Nvidia RTX 4080 has arrived and is no small beast. Packed with power, this GPU is ideal for playing the latest titles at 4K, high settings. We’ve covered the exact performance of this card in great detail in a number of reviews on our website.
Performance isn’t the only chart this card tops, though. It also tops the chart for size, with even the smallest Founders Edition cards coming in at the same size as the RTX 4090 (a triple slot width and 304mm length). We’ve also looked at Gigabyte’s AORUS RTX 4080 design, a GPU which adds on another 20% in length, through Gigabyte impressive ‘Master’ cooler design.
These larger GPU designs lead to a few key questions for those looking to spec up a solid RTX 4080 gaming PC build, one being the size of the case you need to buy. To simplify the process somewhat we’ve rounded up the best cases to buy, covering the best chassis’ that can fit Nvidia’s latest RTX 4000 GPU, the GeForce RTX 4080.

Consumers have the option to build two PCs within this case, with support for server motherboards, a variety of fans and radiators, and custom cooling loops.
Dual preinstalled fans: The HAF700 comes with two 200mm SickleFlow ARGB fans, providing maximum airflow, at much lower noise levels. These fans can be controlled and the RGB can be fully customised using the integrated PWM and ARGB hub included in the case.
Awesome aesthetic: Much like the original HAF700 EVO, the HAF700 has retained the unique futuristic aesthetic. Although this model doesn’t have the LCD display or the front panel glass, it still offers a twist that makes it stand out against other case models.
Things We Don’t Like
Way too expensive: As you can probably imagine, based on the ridiculous feature set, design, and the fact that this is a full tower case, the HAF700 is quite expensive. And you’d be correct, this is definitely one of the pricier cases we’ve seen in recent years, and is definitely geared towards the high-end side of the market.
Not designed for first-time builders: Although the HAF700 offers plenty of versatility, the larger design and support for bigger components can be quite daunting for non-enthusiasts. We definitely recommend avoiding this case if you haven’t built a few PCs in the past.
Summary
Cooler Master’s HAF700 is a cool redesign on the original EVO model, providing a similar set of features with vast support for large and expensive builds. This case won’t be the go-to for the average consumer, but if you’re willing to shell out the money for this pricey chassis, you won’t be disappointed with the build result.
Pros
- Awesome set of features.
- Perfect for crazy big builds.
- Ideal for custom liquid cooling loops.
Cons
- Insanely expensive.
- Geared towards enthusiasts.

How Much Room Does the RTX 4080 Need?
One of the things that I find most confusing about picking up a case is the actual amount of space you need. While the chassis will state the figure surrounding the maximum length of supported GPUs, this often doesn’t account for radiator mounting support or airflow. Parts such as radiators, while necessary, can reduce clearance and vastly reduce the amount of space available for GPUs – something which is important to keep in mind.

The new RTX GPUs are also pretty power hungry, and as such output a fair bit of heat. While the next-gen GPU coolers do a solid job of combatting this, the dissipated heat has to go somewhere – and that’s where case airflow comes in. It is the job of your case to bring cool air into the chassis, and remove the hot air through vents typically located at the top of rear. This means you want to purchase a case with plenty of ventilation, fan mounting spots and preferably a high number of included fans.
Buying a case good in this regard doesn’t have to mean buying a huge tower, contrary to common belief. NZXT’s H7 is a prime example of a case that suffers when it comes to airflow due to the lack of intakes, and the sheer mass of solid panels. Preventing high temperatures coincides with picking a case that has good airflow, so it is always worth looking into what kind of airflow and thermals you should expect in your case. A summary point, don’t stuff components in too closely to the limits of the chassis, and ensure plenty of fans, and you’ll be totally fine from a cooling point of view.
How Big is the RTX 4080?
Funnily enough, the Founders Edition RTX 4080 is the exact same size as the RTX 4090 Founders Edition. Presumably because of this, most of the AIB designs will also be very similar in terms of their physical dimensions when compared to equivalent 4090 designs. To give an indication about the size differences we’ve created a table that covers the dimensions of different AIBs and the Founders Edition RTX 4080 cards.

GPU | Dimensions |
Nvidia RTX 4080 Founders Edition | Length: 304mm Width: 137mm |
Gigabyte AORUS RTX 4080 Master | Length: 357mm Width: 163mm |
Zotac RTX 4080 Trinity | Length: 356mm Width: 150mm |
ASUS TUF RTX 4080 | Length: 348mm Width: 150mm |
MSI RTX 4080 Gaming X Trio | Length: 337 Width: 140mm |

How We Picked the Best Cases to Pair with an RTX 4080
Much like our RTX 4090 article, choosing cases to pair up with the 4080 was relatively simple. NVIDIA‘s new RTX 4000 range of GPUs are pretty gigantic, so finding cases that can fit this GPU is somewhat easy. Case options are limited to some degree, especially if you’re considering clearance, but there are many modern cases that can easily fit the RTX 4080 without any problems.
In order to find cases with plenty of clearance, we’ve ruled out any options that don’t offer at least 50mm of clearance. This ensures that consumers can build a PC with plenty of airflow, and room for other large components, such as radiators and fans. You can read full reviews of some of the cases that we’ve featured below in more depth.

Frequently Asked Questions

Is Motherboard Support A Concern?
Whenever you’re building a PC, clearance and support is always a concern. As a general rule, most modern cases support Mini-ITX, Micro-ATX, and ATX motherboards, with E-ATX being the outlier. You’ll want to check the manufacturer’s website if you’ve purchased an E-ATX motherboard, as support varies between cases.

Recommended Clearance?
In order to choose the cases in this roundup, we’ve picked options that offer around 50-100mm of clearance over the biggest RTX 4080 GPU. This should be more than enough room for airflow, and to fit other large components.

What Wattage Power Supply Do I Need for the RTX 4080?
On NVIDIA’s website, they recommend 750W as a minimum. This is a very baseline number, but your total wattage will depend on the other components you’re using. We recommend picking a power supply that offers around 100W more than the minimum just to ensure you have upgrading room, and enough overhead when boosting.

Can I Install the RTX 4080 in a Mini-ITX Case?
In short – yes. But this entirely depends on the case you’ve chosen, and how much clearance you have. We wouldn’t necessarily recommend a Mini-iTX chassis for the 4080, as the more compact cases can restrict airflow if you don’t have enough breathing room.
