Choosing the Right Case for Your RTX 4090?
Form Factor
The all-new RTX 4090 isn’t your average-looking graphic card that you could put inside any ordinary chassis. This implies that you have to be very specific in terms of your case choice. This is where the form factor game comes into play, to help you identify the correct chassis for your anticipated RTX 4090 build.
The chassis can be bought in different form factors, mainly the ATX, mATX, and mini-ITX. As far as the enormous RTX 4090 is concerned, you can’t go with mini-ITX or mATX cases. This is solely due to the GPU’s size and not related to anything else.
An ATX chassis would be the ideal choice for the RTX 4090. Moreover, having a bigger one also opens the door to a wider range of component compatibility. You can throw in 360 or even 420 mm AIO in selected cases.
GPU Clearance
GPU clearance is one of the crucial things to consider when deciding on a new PC chassis. The sudden leap in graphical power required the cards to be bigger which can be seen in the form of the RTX 4090 - a gigantic card that surpasses its competition out there in terms of dimensions.
To tackle incompatibility issues, opting for an ATX-size chassis is the only feasible solution, and that too from a reputable brand. Occasionally, even the ATX chassis, or as it is commonly referred to as the ATX mid-tower case, is not capable of fully supporting such large-sized components.
So, you better look for such limitations or go with a full-tower ATX chassis, that without a doubt can support any component you throw at it. However, do keep in mind that those cases are quite heavy if that’s something concerning for you.
Airflow
Another important factor of PC chassis is its airflow, which many seem to ignore just to get their desired PC cases. However, we have kept this one in mind and selected only those chassis that do not compromise the system’s airflow. Manufacturers have introduced various workarounds to make both airflow and aesthetics work together.
Just like, some chassis offer an open-air design that only iterates more airflow and less heat. Meanwhile, some make reasonable changes in the good old mid-tower design to optimize the airflow as much as possible for the beefy components.
Lastly, make sure that the chassis you’re going with has airflow in one way or another, otherwise, be ready to read some high-temperature readings on the screen. Airflow highly affects the functionality and life of components, so bear that in mind.
Cable Management
Building an expensive build, and want to make it look like one? Well, in that case, cable management plays a decent part in rendering the build to actually look clean and premium. It’s a mandatory feature, especially for expensive chassis.
They are well-designed with a good amount of cable routing channels and cut-outs with rubber grommets for the cables to slide in easily. Moreover, the expensive iterations of PC cases also include Velcro straps that come in handy to stop the cables from becoming a mess.
Storage Drive Capacity
2.5” and 3.5” storage drives, be it an SSD or HDD, are still one of the most common and widely used means of storing important data. They are not going anywhere, at least for a few more years to come. So, why not get a chassis that gives you a fair amount of storage drive capacity?
The PC cases usually offer 2–3 slots for housing the storage drives, more commonly two for 3.5” HDDs and one for 2.5” Solid State Drive. Luckily, though, the numbers have gone up significantly even in the NVMe era. Which is a good thing for folks with loads of drives lying around.
Build Quality
Now, this is something that one never should compromise on because of the hefty premium that they are being charged. Some manufacturers forget or simply don’t bother to focus on the build of their products, however, they do label an absurd price on it.
Therefore, make sure to check the chassis’ build quality in person or confirm it through reputable review sources. Besides that, the one reviewed here does not compromise on this aspect of a chassis and will offer a top-of-the-line experience in terms of features, build quality, and ease of installation.
Final Words
We hope that this comprehensive guide for the best-rated PC cases has provided you with valuable insights and recommendations that helped you to make an informed decision to select the best PC case for your RTX 4090. Many factors such as cooling, compatibility, size, aesthetics, build quality, and other additional features were thoroughly discussed to allow you to find the case that perfectly complements your RTX 4090.
