Best Case for RTX 4090

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, 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, the capability to host large radiators, etc., and the capacity to house the most powerful motherboards available.

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. These specs can pull out some great performance, and pairing a crisp-looking high refresh rate monitor with it is wise.

The graphics card’s memory is also 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 which demands a beefy and reliable Power Supply to be installed.

Nvidia RTX 4090 Graphics Cards	GPU Dimension	Recommended Case Clearance
Nvidia GeForce RTX 4090 Founders Edition	304mm/137mm	340mm+
MSI GeForce RTX 4090 GAMING X TRIO	337mm/140mm	400mm+
ASUS ROG STRIX RTX 4090 GAMING OC	358mm/137mm	400mm+
Gigabyte GeForce RTX 4090 GAMING OC	340mm/150mm	400mm+

You have to ensure many things for a case that can host a behemoth like RTX 4090. First, you must ensure that the graphics card can 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.

Best Case for RTX 4090 Reviews

Corsair released the iCUE 7000X at an MSRP of $299, a few standard deviations above the typical PC case price. The case has a 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 not very ordinary. If so, with the vast array of expansion options and excellent cooling this case provides, you would likely need to buy another case quickly if you go with it.

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 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 quietly, so much so that they almost forget that any fans are 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 this is the best case for most users to meet their requirements while leaving space for more without any dents on their finances.

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 plenty of maritime space to install all the components easily. Unlike the other PC cases we reviewed, the side glass panels have plastic edges for safety and use a screwing mechanism to lock into place. This scheme is outdated but not too big of a deal.

By default, the case has 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 use the additional HDD cages. 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 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.

Next is the full tower casing from the Cooler Master product lineup, the Cosmos C700M, 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, 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.

Next up on the list is another casing 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, which 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 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 has many features; it’s a pure price-to-value product you can use to hook in an RTX 4090.

How to Choose PC Case for RTX 4090

Form Factor 

One of the key things to consider beforehand is the knowledge of that specific product; in this case, the form factor is one of them. In the commercial market, there are 3 known sizes, one of which is ATX, then microATX, and mini-ITX. 

These are the widely used sizes even in motherboards; hence, chassis is also available in those sizes to accommodate motherboards of different sizes. The mini-ITX chassis is for tiny PC builds that can only accommodate mini-ITX motherboards. microATX chassis can house mini and micro, both motherboards and then comes the biggest of them all; ATX can house all three types of motherboards and much more.

Clearance for GPU

Graphics Card is one of the core components of a gaming or productivity PC build and hence, requires a sufficient amount of space in the case to fit and work. Nowadays, graphics cards have become much more powerful, which asks for a spacious chassis. So, before getting yourself the new shiny chunky graphics card, ensure your PC case has enough room.

You can either measure the space available manually or search the web about the measurements of your chassis and what size of the graphics card it can hold. Almost every ATX chassis has enough room to accommodate any graphics available.

Airflow of the Chassis

Airflow is the most crucial thing to consider while finalizing a case for your next or existing PC build. Your components’ overall performance and health can get affected if the airflow inside of your chassis is not optimal. Nowadays, chassis come with various methods of cooling. 

Some chassis have mesh front, which improves the cooling significantly, and most chassis also come with a top meshed fan mounting system for maximum airflow. You can place 2-3 fans at the front for intake and the top and rear for exhaust. This is the most used and traditional way of making your chassis’ airflow optimal for the components inside.

Cable Management

A premium case costs a lot, and hence people expect a lot in return, too, one of which is the ease of managing cables. However, this feature is wider than premium offerings as the manufacturers have started providing layouts for cable management. Some even provide accessories like velcro straps to tie up all the cables in one place. 

This is one of the points to consider so you don’t end up with a mess of cables at the back because of the lack of velcro straps or available space and layout for the cables. 

Room for Storage Drives

The tech is advancing, and so is the size of storage devices, and it has now come to a point where you don’t even need space in the chassis to place it because you can now direct install it on the motherboard. However, those M.2 NVMe drives are expensive, so most people still go for the good old 2.5” and 3.5” SSDs and HDDs.

And to accommodate those old drives, you need space in your chassis; most manufacturers provide at least 3-4 slots for placing these old drives, which is more than enough for the majority. However, many people out there still need more than 3-4 slots and must get a chassis that can accommodate drives according to their demands.

Conclusion

With the article ending, it sure needs a conclusion to make it a bit easier for everyone’s reading. I’ve compiled some of the finest-looking and most practical chassis for your next build in this article. Each of them comes at a different price point and offers inventive features. 

Starting with an under 200$ budget chassis, you can choose from a variety of cases here, one of which is the NZXT H7 Flow, and then comes Corsair 5000D, Phanteks  Eclipse P500A, and Phanteks Enthoo Pro, which are priced at 130$, 175$, 163$, and 150$ respectively. These chassis have high-grade build quality, airflow, and aesthetics. 

Moving forward to a higher budget, say, between 200 to 300$, you can choose from some of the premium offerings like Lian Li O11 Dynamic XL ROG Certified for 220$, which is a spacious dual chamber styled enclosure and has been built finely. Then comes the Asus ROG Strix Helios GX601 RGB Mid-Tower, heaven for RGB and ROG series lovers, as the ROG branding and RGB LEDs are all over the case. And in the end, we suggest the CORSAIR iCUE 7000X RGB, a full tower case to accommodate bigger and chunky components like the RTX 4090 and Full ATX motherboards.

Not to mention, for the high-end ultimate chassis lovers, there’s an offering from Cooler Master, which is its Cooler Master Cosmos C700M E-ATX that comes bundled with a GPU riser kit and curved glass panel all over it for an extra bit of premium feel. This brief conclusion would assist you quite a bit in terms of going with the right chassis for your next build.
