Best case for RTX 5090

The Nvidia GeForce RTX 5090 is the latest and most powerful GPU we’ve ever seen. If you're going to be eyeing up a third-party card, then it could also be the biggest ever too. This means that if you’re looking to make the upgrade, it’s not just a question of getting a new PSU, it might not even fit in your case, and if it does, it might be a tighter fit than you’d like.

So, why not refresh your entire setup with a case that’s up to the task. Luckily, CORSAIR makes many such cases, so we’re going to give you our fave options right now.

Amazingly, Nvidia has managed a minor miracle with its own take on the RTX 5090, managing to squeeze all that power into a card that's just two slots wide. It's impressive, make no mistake. It really isn't a bad looking card either.

The likes of Asus, MSI, Gigabyte, and the like are going to want to push this card a little harder though, and then means producing a graphics card that can take up to 3.5-slots and dwarf plenty of cases. So with that in mind, let's get going with our recommendations.

The biggest, most overkill GPU will pair nicely with the biggest, most overkill case, and that case is no one other than the CORSAIR 9000D RGB AIRFLOW.

The fitment concern of the biggest RTX 5090s entirely disappears in a case like this. So do the cooling concerns, the question of future upgradability, or swapping to a water-cooled build. Basically, the 9000D no limits. Just make sure you’ve got space for it.

• Max GPU Length: 400mm
• Max CPU Cooler Height: 180mm
• Case Length: 698mm
• Case Width: 307mm
• Case Height: 698mm
• Fan options (Front): 8x 120mm / 3x 140mm / 2x 200mm
• Fan options (Top): 8x 120mm / 3x 140mm / 2x 200mm
• Fan options (Side): 3x120mm
• Fan options (Rear): 2x 120mm / 1x 140mm

Additionally, it’s designed to house two entire PC builds inside, so those looking for separate streaming and gaming PCs can combine two distinct systems into a single case.

Those who are not in need of such capacities might opt for the more pedestrian, and therefore more affordable, but still plenty capable CORSAIR 5000D. This is a mid-tower case on the larger side and this additional size does have some strong benefits.

• Max GPU Length: 420mm
• Max CPU Cooler Height: 170mm
• Case Length: 520mm
• Case Width: 245mm
• Case Height: 521mm
• Fan options (Front): 3x 120mm / 2x 140mm
• Fan options (Top): 3x 120mm / 2x 140mm
• Fan options (Side): 3x 120mm
• Fan options (Rear): 1x 120mm

Firstly, it’s large enough to house a 5090 and as compared to some other mid-tower cases, it can accommodate a 360mm AIO up top, in the front, or down the side to the right of the motherboard tray. A 360mm AIO is the correct option for the overly spicy CPUs that have become the norm today, and three potential mounting locations mean you have more options depending on your other components.

If you’re keen on the look and functionality of the 5000D, but you need more room to work with, the 7000D is an excellent choice. It’s taller and longer than the 5000D, which gives you more options for AIOs, and there’s more space inside, so it makes live easier for those looking to get into custom cooling.

• Max GPU Length: 450mm
• Max CPU Cooler Height: 190mm
• Case Length: 550mm
• Case Width: 248mm
• Case Height: 600mm
• Fan options (Front): 3x 120mm / 3x 140mm
• Fan options (Top): 3x 120mm / 3x 140mm
• Fan options (Side): 4x 120mm (Requires removal of cable cover)
• Fan options (Rear): 1x 120mm / 1x 140mm

We also see compatibility with GPUs up to 450mm, which is enough to handily accommodate the biggest of RTX 5090s, or any GPU from the 50-series. If you’re looking for a large case that’s easy to work in, and is a prime candidate for watercooling, the 7000D is what you’re after.

If you’ve grown used to traditionally shaped PC Cases, then swapping to a dual-chamber design is a welcome breath of fresh air. The 6500D is CORSAIR’s newest offering in this category and it’s worth considering for the RTX 5090 for a few reasons.

• Max GPU Length: 400mm
• Max CPU Cooler Height: 190mm
• Case Length: 698mm
• Case Width: 307mm
• Case Height: 698mm
• Fan options (Front): 3x 120mm / 2x 140mm
• Fan options (Top): 3x 120mm / 3x 140mm
• Fan options (Side): 3x120mm
• Fan options (Rear): 1x 120mm; 1x 140mm

Chief of which is the cooling layout. With the PSU secreted behind the motherboard tray, you can mount fans to the floor of the case, this creates maximum airflow straight up into the GPU. This leaves the front and side intakes prime real estate for an AIO cooler, or just more intake fans if you’re old school and prefer an air cooler for your CPU.

Note that you’ll lose the ability to mount fans in the front if you opt for the 6500X, as the fan mounts are replaced a glass panel.
