Best cases for RTX 4080 in 2024

Space, airflow and performance all count, but which cases make the list?
Last Updated on January 11, 2024
Asus ROG Strix Helios

Productivity, creativity, gaming. Those are the things that come to mind when we think of GPUs. And when it comes to the best of the best for performance, the RTX 40-series is the way to go. But they’re big, which is why we’ve produced this list of the best cases for the RTX 4080.

Building a rig with the 4080 in mind becomes simple when you accept the fact that these are really big GPUs. With the release of the RTX 4090 size came as a surprise, but by this point, we should already be prepared for the dimensions of Nvidia’s ADA cards.

As a side note. If you’re looking for a case for your brand new RTX 4080 you must keep in mind that you’ll need a powerful PSU too. Although power efficient, these are also power-hungry cards and standard power units won’t suffice the GPU’s needs. So your case will also need space for a bigger and more capable PSU.

How we picked the best cases for RTX 4080

We begin by analyzing a large set of cases and narrowing down our options, so our recommendations are ideal for a sizeable graphics card and leave sufficient space for airflow.

Additionally, we ensure that we’ve picked cases that looked good but are as economical as possible so that you can get the best value too. But in all there’s a list of five areas that we kept in mind when selecting the best cases for the RTX 4080:

● Performance
● Design (temper glass side or not)
● Price
● Configuration

  • Superb aesthetics
  • A lot of space for cooling
  • Interchangeable drive bays
  • Not cheap

Lian Li is a household name in the computer case world. We couldn’t list the best cases for the RTX 4080 without referencing the company, and for a good reason. The Lian Li O11 Dynamic XL is the best Liam Li case right now. After reaching incredible sales with the older version of the Dynamic, the brand decided to make it bigger and better; and it managed to do so. This case is made of an aluminum plate with tempered glass on the front and side, and is available in white, silver, and a Razer edition.

This case can serve any standard ATX, mini ITX, or micro ATX motherboard, as it features built-in motherboard support. The dimensions are 23.75 inches by 15 inches by 23.3 inches, and it is modular so you can customize it as much or as little as you please.

Another beneficial feature of this case is that it is capable of handling a second 120 mm fan and can accommodate a thick radiator at the bottom of the system even when installing dual graphics cards or vertical. That’s perfect for housing an RTX 4080 because it means you can optimize for airflow and cooling to ensure your card can work at its best. 

Space is a key issue for Nvidia’s card, and the video card space reaches a length of 446 mm, permitting it to hold the 304 mm of the RTX 4080 without issue.

  • Good price
  • Awesome design
  • Extremely modular
  • Dust magnet

It’s hard to come across a case that really seeks to make itself completely varied to the outward market trends of the chassis world, yet Thermaltake proves time again it can rise to the occasion. The firm’s Core P3 Pro takes on a rather interesting design language, leveraging the potential for wall mounting, as well as an open-air design that makes it look almost unfinished.

That’s just how this PC case sets itself apart from the rest among the best cases for the RTX 4080. The product is extremely robust, with a highly modular design that fits mini-ITX, micro-ATX, and ATX boards. The open-air design likewise allows users to customize their rig literally to their heart’s content, meaning a 4080 – or even three 4080s – will fit just fine.

  • Maximum PSU Length: 220 mm
  • Powerful fans
  • Great stock thermal performance
  • Fans can be noisy

The Asus ROG Strix Helios is a beautifully designed case designed with aluminum, alloy, and tempered glass. If you’re looking for a case that looks great with many elements, you’ll appreciate the ROG Strix Helios.

The RGB lighting on the front panel glass is made to leave an impression, but this case does more than look good. This case has pre-installed black fans (3 x 140 mm), a Removable dust filter, and a Special PCI slot bezel. Plus, there’s an additional SSD bay, cable ties, and a warranty card included.

As for why it’s on our best cases for RTX 4080 list, it will comfortably house the 4080 too – or any big GPU: this case has dimensions of 250 x 565 x 591 mm dimensions.

For the cooling system, as a good E-ATX case, the ROG Strix Helios can house multiple fan sizes alongside the rear and on top. So there’s enough options for airflow management to keep your system cool too. 

  • Optimized for high airflow
  • Includes 2x CORSAIR 120mm AirGuide fans
  • Cable management is not its strongest feature

The Corsair 5000D Airflow is a case dedicated to maintaining a cool inside temperature for the components housed inside. The design of the casing allows air to flow as freely as it can; hence the name.

Moreover, what makes the 5000D Airflow a worthy recommendation is the amazing price-to-performance ratio. It showcases a solid and subtle design, basing all of its benefits on performance. And yet, the case can be found for well under $200. However, one consideration is that cable management in this case isn’t the asiest.

Still, this is a good unit that will accommodate multiple drives. The CPU clearance is 170mm, allowing for a good array of coolers, and the GPU clearance is 400mm, which ensures that your RTX 4080 will fit easily.

The 5000D is available in white and black with a side tempered-glass panel. If you’re a fan of minimalism in design this is likely a good option for you.

Features and considerations

The first thing to consider before buying a case for the RTX 4080 is the dimensions of the GPU. In a direct comparison with the previous iteration, we can see that this is a big GPU.

RTX 4080 specs:

  • Length: 304 mm
  • Width: 137 mm
  • Slots: 3-slot (61 mm)

RTX 3080 Specs:

  • Length: 285mm
  • Width: 112mm
  • Slots: 2-slot

A GPU this size will need a big motherboard. So we can start leaving behind the micro-ATX boards. You’ll likely have a standard ATX or even an E-ATX any of the cases will be great. Just keep that in mind to choose the size of your case.

Once you’ve balanced the size out, the next feature to consider is heat dissipation; a bigger case will provide more space for cooling systems, thus a better overall performance from the rig. So, if you’re planning to do some overclocking, high-end gaming, or top-notch content creation you’d be better off with a bigger form factor such as an E-ATX.

And that’s all of the best cases for the behemoth that is the RTX 4080. Your case should not only speak volumes of the many awesome components hidden within its bowels but also speak to you on an aesthetic level. Maybe you want something with a ton of breathing room, or you’re fine with a cramped rig interior. It’s your creation, after all!

How big of a case do I need for 4080?

We recommend at least the following PC case dimensions for the 4080: 201 x 435 x 435 mm. This will ensure you have space to fit the 4080, have a decent amount of airflow, and work around it for cable management and access to other components and elements of your build.

How big is the 4080?

The 4080 (Founders Edition) has a length of 304 mm, a width of 137mm, and takes up three slots (61 mm). That’s pretty big. While it’s smaller than the RTX 4090, that base size will increase for partner cards, which aren’t as chic and slimmed down due to cooler and construction add-ons.

Our Verdict

In our view, the Liam Li O11 Dynamic XL is the best case for a big GPU like the RTX 4080. It is spacious, well-ventilated, and has excellent cable management features.

So, if you are looking for a high-quality case that will allow your RTX 4080 to perform at its best, the Liam Li O11 Dynamic XL is the case for you. If budget is more important, opt for the Kolink Observatory. Or, if you simply must have a ROG case, the Asus ROG Strix Helios is a solid option too.
