A computer case plays a significant role in the operation of a PC because all the components reside inside it and can face tough thermal conditions if the case is not up for the job. There are multitudes of cases available on the market these days, most of which are gaming cases. A gaming case is no different from non-gaming cases, except for the design, as it targets gamers and thus uses gaming-oriented color themes and styles. This article will check the best case for RTX 4090, so have a seat.

Many form factors of cases are available these days, although three are the most common. The mini-ITX SFF cases are the smallest available on the market, and they are designed for users looking for a portable system or at least a system with a small footprint. The mid-tower cases are the most common cases on the market, and these are usually cheaper than the mini-ITX and full-tower cases, although they could be better in terms of features and performance. The full-tower cases are the largest and come with the most advanced features such as ThunderBolt port, capability to host large-sized radiators, etc.

NVIDIA GeForce RTX 4090 is the fastest gaming graphics card and one of the most expensive. NVIDIA has gone all out in this generation, and the result is this massive bulky unit with 16384 shader processing units, 512 texture mapping units, and 192 render output units. The base clock of the graphics card is 2235 MHz, and the boost clock is set at 2520 MHz, which is even higher than the RTX 4080.

The graphics card’s memory is also quite impressive, with a 384-bit memory bus width leading to an effective memory clock rate of 21.2 Gbps. The overall memory bandwidth is rated at 1018 GB/s, roughly the same as the RTX 3090 Ti. The power consumption of the RTX 4090 is also the same as the RTX 3090 Ti, at 450 watts.

Now, for a case that can host a behemoth like RTX 4090, you have to ensure many things. First, you must ensure that the graphics card can physically fit inside the case you are considering buying. This goes for both the length of the graphics card as well as the height of the graphics card.

The 8 Best Case for RTX 4090 Reviews

Reasons to Buy

  • Neat cable management.
  • Flexible in terms of expansion.
  • Professional looking.

Reasons Not to Buy

  • Massive size and weight.
  • A bit overkill.
  • Expensive.

Corsair released the iCUE 7000X at an MSRP of $299, a few standard deviations above the typical PC case price. The case has a very solid and professional look and can house most modern motherboards, such as the Mini-ITX, Micro-ATX, ATX, and E-ATX. As graceful looking as it is, it is a little too heavy due to its above-average dimensions and the massive radiators (in case of liquid cooling).

The assembling is user-friendly because the internals can easily be accessed as the side panels can be latched open and pulled outwards like a door if you want to go full hands-on with the inner components in a trouble-free manner, the option of completely separating the panels from the case by removing the screw atop the hinge that connects the panels to the casing.

Thanks to the multiple fans, the airflow is excellent in this case. By default, there is one 140mm fan on the rear side and two on the front side, with multiple extra slots on the top for additional fans. The peak fan speed is 1250 RPM, which means the noise levels are very low during non-intensive usage. The dust filters on the front and top side ensure the internals remain clean and cool for flawless operation.

The upgradability of components is the main highlight of this case due to its massive volume and slots. You can, for instance, mount 6 HDDs and 3 SSDs under the PSU. With typical HDD storage sizes already larger than 1TB and SSDs fast catching up, the amount of memory that can be added to this system is only limited by your imagination.

So, is this the best case for RTX 4090? If you are buying an RTX 4090, chances are you are not on a budget in the first place, and your workloads are, thus, not very ordinary. If so, with the vast array of expansion options and excellent cooling this case provides, it is likely that you would need to buy another case in a short time if you go with it.


I am going to start the list with a casing that belongs to a well-known brand in the PC community. Lian Li is a veteran in catering to the PC community’s needs, and it thrives in delivering high-profile casings with plenty of airflow and space to host your components, no matter the form factor.

The Lian Li O11 Dynamic XL is an upgrade to the Lian Li O11 Dynamic, which is built from Aluminum and has a tempered glass front and side panel. The latter is a mid-tower chassis, and due to a lot of demand from the community for a bigger chassis of the same design. Lian Li listened to their loyal fan base and gave us a Case bigger in size with the same features and more space.

Since it’s a big chassis, it has supporting motherboards with large form factors such as ATX and E-ATX. It’s a modular case with a removable rear panel held by thumbscrews. It has very good airflow and the temperatures stay down, with the temperature range between 49 to 67 degrees and factoring in the ambient temperature.

The dimensions of the case are 471(D)x285(W)x513(H)mm, making it quite spacious and large for hosting the PC components. It has a CPU clearance of 167mm, 8 expansion slots, and can host up to 13 fans in the casing for maximum airflow. Furthermore, you can add 360mm, 280, and 240mm radiators with ease as well. The case has been designed in collaboration with the German Overclocker DER8AUER, who made the O11D product lineup famous due to his positive endorsement.

The GPU length is 446mm, which is perfectly capable of handling a large GPU such as the RTX 4090, which is a behemoth of a GPU, considering it’s one of the top-end GPUs by Nvidia at this point. To top things off, it even comes with multiple dust filters, and it is available in three colors, Black, White, and Silver, making for a very aesthetically pleasing PC should you go for it.


Next up on the list is the Phanteks Eclipse P500A D-RGB, which strikes a fine balance between airflow performance, looks, and aesthetic value. It’s a steel chassis, and Phanteks offers it in the premium casing category.

The casing comes with a 1mm Ultra, fine performance mesh on the front panel, optimizing airflow and effectively filtering dust. It’s a mid-tower casing, and like all other casings featured on the list, it has interior space to host motherboards from all form factor ranges, from EATX to MITX. Due to its spacious interior, there is ample storage space as it allows you to host 13 SSDs and 10 HDDs, which is quite a lot if you ask me.

Since it has ample space for airflow and for hosting components, you can hook in a radiator up to 420mm, thus giving you extensive water-cooling options. For maximum and optimal airflow in the casing, you can hook in 7 fans, including the radiator at the front, the top, and a single fan at the rear.

The case’s dimensions are 240mm x 510mm x 505mm, which means that it has more than enough space for all your PC components and future upgrades. With a CPU clearance of 190 mm, it can run a large custom water loop or a large radiator to keep the temps down. With a GPU clearance of 435mm, the casing has ample space for hosting a large GPU like the RTX 4090.

The side panel is tinted tempered glass, with 7 PCIe horizontal slots and 3 vertical PCIe slots. It’s a solid casing that perfectly combines quality and performance. It is designed for people looking for something that isn’t mainstream but has all the high-end features that a good casing has, such as a spacious interior, ample airflow, and multiple expansion slots, making it one of the best cases for RTX 4090.


The ROG series product lineup has such a large and diverse product lineup that they are always popping up in our reviews due to their quality. The product lineup contains every PC component used by the PC community, from peripherals to GPUs. Asus has exponentially expanded the ROG series, and they are praised among the PC community, especially hardcore gamers and enthusiasts.

The ROG Strix Helios GX601 is a premium and high-end mid-tower casing with all the high-end features you would need to build a top-of-the-line PC. The integrated front panel lighting in black gives it a unique outlook separating it from the competition. The casing has an aluminum frame and three 4mm tempered glass panels.

It’s a beefy casing with 250 x 565 x 591mm dimensions. It’s an EATX form factor compatible casing, which means you can host all motherboards. There is a built-in cable management system with a multifunction cover for a sleek and clean PC look. The interior has ample space for hooking in extensive water-cooling setups, ensuring the temps stay down.

There are multiple USB ports on the front panel, and even a Type C port is also there. The Helios has the ROG logo on the front, which screams that this casing belongs to the ROG product series. The front panel can feature 4 120mm fans with rotatory speeds of up to 1400RPM. The RGB featured at the front can be synced with an Asus board using the Aura Sync software. There is also the presence of audio jacks on the front where you can hook in your headphones.

Since it’s a big case, it can hold up to nine storage drives within, and due to the GPU clearance being 450mm, it has more than enough room for hosting a large and top-end GPU like the RTX 4090. The casing has all the features you would need in a high-end casing, combined with the space, its expansion slots, internal features, and outlook, and it is indeed one of the best cases for RTX 4090.


Next is the full tower casing from the Cooler Master product lineup, the Cosmos C700M, which is a direct successor to the C700P. Over the years, Cooler Master has worked on refining the casing design, and with every new iteration, they have made it better in every way, which is why it has become a fan favorite.

The Cosmos C700M is one of the biggest casings you can get for your high-end PC. The casing is a perfect mixture of classic and modern designs. In the previous generation, the side panel was heavily tinted, but the tint has been reduced for better visibility inside.

The casing is a full tower case and has a steel frame. The dimensions of the case are 650 x 306 x 651mm, which means it can support motherboards of all form factors such as EATX, ATX, MITX, etc. You can hook up to 420mm AIO water-cooled radiators at the front or top. There is a lot of space!

If you are a sucker for RGB, then this case has you covered. It has RGB strips from the back of the top panel and goes to the bottom in a continuous line. Moreover, these RGB strips can be addressed on the individual level. The front panel can be removed using the metallic contacts present. There is plenty of ventilation, and the optimum airflow due to the case’s design helps keep the temps down and run your PC at extreme conditions with maximum stability.

The casing has 8 expansion slots and around 9 drive bays to host your storage. Due to the interior space present in the casing, the CPU cooler clearance is 198mm, and the GPU clearance is 490mm, which can easily host a large GPU with space to spare.

The only downside is that since it’s a large casing with a lot of space, it also comes with a large price tag. But the features and utility that the case brings to the table make it one of the best cases for RTX 4090, and while it’s a hefty investment, it will be a solid one.


Reasons to Buy

  • Reasonable price.
  • Highly Spacious.
  • Good Cable Management.

Reasons Not to Buy

  • Plastic-build feels cheap.

The Phanteks Enthoo Pro is one giant chassis. It is a highly spacious, Full tower ATX case that provides good cable management and can fit motherboards of any available form factors in the market these days. The front side is a plastic build, which feels a little cheap, but we can’t complain about it considering all the other goodies it comes with at its $130 MSRP.

Its massive size means that there is plenty of navigational space to install all the components with ease. The side glass panels have plastic edges for safety and use a screwing mechanism to lock into place, unlike the other PC cases we reviewed. This is a little outdated scheme, but not too big of a deal.

By default, the case comes with two stock fans, 1x200mm on the front side and 1x140mm fan on the rear side. The many slots around its sides, coupled with HDD cages that can double as fan slots, means that you can easily mount up to 10x120mm cooling fans. Liquid cooling is also supported, where you can install up to 420mm radiators.

The minimum clearance for the graphics card is 347mm if you also put the additional HDD cages to use. This is still more than enough space to add the RTX 4090. The large tower volume and space for many fans means that temperatures aren’t going to be an issue, and the GPU can be safely pushed to its limits, making it one of the best cases for RTX 4090.

It also comes with 6x3.5” bays and 7x2.5” bays for adding HDDs and SSDs, respectively. With even single HDDs having capacities of tens of terabytes, using this tower, your PC can easily act as a home server for your website, considering the amount of storage space it can hold at any one time.

So, who should buy this PC? Most people are more concerned with aesthetics than practicality and value for their money. It is affordable enough for a budget build and expandable enough to house even the most powerful hardware while maintaining adequate cooling.


Reasons to Buy

  • Very little fan noise.
  • Decent looking.
  • Good cable management.
  • Affordable price.

Reasons Not to Buy

  • No reset button.

The NZXT H7 Flow retails at a very reasonable price of $130. It is a decent-looking, mid-tower ATX Chassis suitable for both budget and high-end builds. It has a lot of space for housing large motherboard sizes, although it is recommended that they be kept below 10.6”.

The PC building exercise is also smooth and trouble-free. The side-mounted glass panels can easily be latched off and snapped back into their place. There is a cable shroud present, too, for neatly managing cables.

The default fans are sized at 120mm, but larger fans can be added. For instance, the top panel has slots for housing three additional 120mm fans or two 140mm fans. There is also enough space to add a 360mm radiator to enhance cooling performance. The fans run very quietly, so much so that they almost forget that there are any fans present in the first place.

The vents on the case are designed in the shape of perforations. There are dust filters behind each vent too. These filters keep the internals clean and reduce noise levels. However, it comes at the cost of slightly higher CPU temperatures, but nothing alarming.

The case provides respectable options for storage expansion with its two 3.5” bays and four 2.5” bays for additional hard disk drives and SSDs, respectively. Two sleds for housing SSDs are already mounted inside the chassis, while the remaining two come inside the box.

The maximum GPU length the case allows is 400mm, which is large enough even vertically to mount the ~300mm long RTX 4090 with still 100mm to spare. The impressive cooling provided by the extensive inside with space for radiators and multiple fans means the card can be maxed to its limits without any risk of thermal throttling.

So, what’s our verdict? Well, this is one of the few items we have ever reviewed that don’t have any significant cons. We believe that this is the best case for most users to meet their requirements while leaving some space for more without any dents on their finances.


Next up on the list is another casing that is also manufactured by a company that caters to the PC community with its versatile product lineup. I am talking about Corsair, which has made a name for itself by delivering products tailored to the community’s feedback.

If you are looking for a mid-tower casing that gives a clean look, hides your cables, and gives you extra space for airflow and cable management, then you should go for the Corsair 5000D casing. It also has ample soundproofing, so it will muffle the noise when running it in extreme conditions. It even has a mesh dust filter at the front to offer protection from dust.

The dimensions of the casings are 245mm x 520mm x 520mm. This means that there is plenty of space for expansions in hardware, and more importantly, there is ample space for hooking in the air-cooled or liquid-cooled loops (240mm or 360mm), which will keep the temps down.

For maximizing airflow, Corsair has included two Airguide 120mm fans containing vortex vanes for directed airflow, thus further optimizing the air currents in the casing, ensuring that the hotter running components get exposed to more air than others.

The casing supports motherboard form factors of EATX, ATX, and Mini ITX, meaning that you can hook in any motherboard regardless of size. However, that’s not recommended; the Corsair 5000D has the space to host a motherboard of any size.

Multiple SSD storage options are also present, allowing you to expand later on or have multiple SSDs from the start if you have the budget. The clean look of your PC comes from a lack of cables, and for that, Corsair has given a single hidden channel present behind the motherboard, which is 25mm in size, and it hides behind a hinged steel door, where you can push your cables into thus hiding them from sight.

To top things off, the casing comes with vertical PCIe slots and a screw mount, which you can use and hook in your GPU vertically to show off. Overall, it’s one of the cheapest casings out there and comes with many features; it’s a pure price-to-value product that you can use to hook in an RTX 4090.
