Best PC Case in 2025

Last updated:

Finding the best PC case for a new build is arguably the most important step in the process of building a gaming PC. It determines what kind of motherboard you can use, how big a GPU you can install, and how large a CPU cooler you can fit.

Additionally, it defines how the finished product will look and, depending on the size, where the PC will live at the end of it all. So, after giving you the best options from the considerable broad range of CORSAIR PC cases, we’ll go over some things to keep in mind, regardless of which brand you’re considering.

Best Mid-Tower Case: CORSAIR FRAME 4000D

The FRAME 4000D provides an open and easy building process courtesy of its innovative modularity and accessible size. Despite the sensible dimensions, it can fit a full 360mm AIO up top and can quite easily house almost any modern GPU. Additionally, the modular design allows for future customization, via alternate parts from CORSAIR, or 3D-printed creations of your own.

Best Fishbowl-Style Case: CORSAIR 3500X

Those who value a tidy aesthetic will likely be drawn to the panoramic computing vista provided by the 3500X. With the side and front panels entirely made of clear tempered glass, this is a case for those who take pride in their building skills. A nice benefit here is that both panels pop off, making for perhaps the easiest building process CORSAIR has provided to date.

Best Dual-Chamber Case: CORSAIR 6500X

The CORSAIR 6500 is a dual-chamber case. This means the chassis is split in two lengthways, moving the storage and power supply directly behind the motherboard tray, which creates some advantages. It greatly simplifies cable management and provides more options for cooling, which appeals to the performance-oriented.

Now that the bottom of the case doesn’t have to house a PSU, you can go wild with fans. Additionally, with the motherboard tray pushed forward, an All-in-One CPU Cooler can be positioned in the side intake, so the radiator doesn’t eat into the functional space above the motherboard.

Best Budget PC Case: CORSAIR 3000D

If you prefer to allocate less of your budget on your case, and pump it all into the core components, then the CORSAIR 3000D is the right choice for you. It lacks some of the premium features of the other cases in this list, but it’s optimized for airflow and value, which is what really counts when it comes down to it.

Best Large Mid-Tower Case: CORSAIR FRAME 5000D

The CORSAIR FRAME 5000D takes everything we debuted with the FRAME 4000D and makes it a little bigger, a little more capable, and adds a few nice touches, like expanded front I/O, space for 3x 140mm fans (and therefore a 420mm AIO up top), and a subtle RGB strip below the aforementioned I/O panel.

Best SFF Case: CORSAIR 2500X

Despite the ever-growing size of GPUs, Small Form Factor (SFF) cases are, paradoxically, increasing in popularity. And the 2500X is a great choice. Retaining the dual-chamber layout of the 6500, this case compresses it down to a compact size for those who like a small case, and don't mind, or indeed embrace the additional efforts required to build in an SFF case.

PSU Compatibility SFX or ATX

As with the 6500X, there are far too many variants of this case to list, but you can get it with a glass front panel or a perforated airflow front panel, in black or white, with RX120 RGB fans, or without. And the 2500 cases have the same options in terms of aftermarket materials for the panels.

What to Consider When Buying a New PC Case

So, with our favorite CORSAIR cases out of the way, let’s take a moment to talk about what you should consider when browsing for a new case, regardless of which brand you’re looking at.

Size

To be clear, when we say "size", we’re specifically referring to the exterior dimensions of the case. If you keep your computer on your desk like you should, then the size, especially the width, is of utmost importance. Getting a new case and building a full system in it, only to find out it doesn’t fit where you need it to is heartbreaking stuff.

GPU Clearance

It’s funny, because this wasn’t always an issue. Indeed, just a few short years ago you could be pretty damned cavalier when it came to picking a case regardless of your GPU because the cards just weren’t that big.

This is no longer true, and it’s now surprisingly easy for even a regular mid-tower ATX case to be too small for some graphics cards. We make sure to validate the maximum GPU length on all our cases so you can be sure before buying. Remember to check the length of your GPU against the specs of the case you’re looking at.

Fan and Radiator Capacity

When it comes to cooling, more is better. This is not to say that you need to max out the case right off the bat, but it needs to have enough space for a decent number of fans. At minimum, you should look for at least two intake fans and two exhaust fans. All the cases on this page are capable of fitting more than that, but that’s a baseline you’d want to hit.

Additionally, where fans can fit, radiators can fit too. Usually. This is not a hard and fast rule, as a radiator, in addition to the necessary fans to run air through it, can combine to be thick enough to interfere with nearby components.

If you’re opting for an AIO (all-in-one) cooler instead of an air cooler, we recommend a 240mm AIO as a minimum, but a 360mm unit will perform noticeably better. So, look for a case with 3x 120mm fan mounts all next to each other. If you can find this in your case, chances are a 360mm AIO will fit there just fine.

Design

We aren’t going to waste time getting prescriptive with this one, because it’s definitionally subjective. However, be aware that you’ll have this case in your office, bedroom, study, etc. for a long time. So even if you like the look of any given case in a vacuum, take a moment to consider if it works for the environment you’re going to put it in.

Price

Again, this is difficult to write about with any sense of authority, because it’s your money and therefore your concern and your concern alone. So, instead of talking in terms of Dollars, Pounds, Euros, or Dirhams, we suggest thinking about it as a percentage of your total build budget.

There is no real upper limit to how much a PC case can cost these days, but if the price of the case constitutes more than about 15–20% of the overall cost you’ve allocated to building a new PC, then take a step back and think. Perhaps that share of the budget could stand to be reduced so that another component or components could be upgraded?

Try the CORSAIR PC Builder

If you've already decided on your dream PC case, but have doubts about the complex and frankly tedious process of verifying compatibility with everything, check out the CORSAIR PC Builder tool.

This allows you to create your PC build step by step and checks compatibility for you. It's not just limited to CORSAIR parts either, so you can try it out even if you've got some non-CORSAIR stuff in your list.
