The best computer cases for 2020

A custom-built PC gives you the chance to make all the specs exactly what you want, and the case is your chance to show off your personal style. Manufacturers continue to innovate with new materials and features, giving you more choice than ever when it comes to housing your build.

From cutting-edge designs that will attract attention to cases built for simplicity and durability, we’ve narrowed down the best the computer cases you should consider.

Cooler Master Cosmos C700P

The combination of durable brackets, mesh panels, and a thorough cable cover system gives this Cooler Master case the edge over almost all the alternatives. The design can be conventional, inverse, or personalized, depending on exactly what hardware you want to include. Even the cable system has three different covers to choose based on your goals and what type of storage you use.

While RGB lighting and controls are included, you can always augment it with a colorful memory kit, if you wish. The built-in, slightly tinted, tempered glass side window allows everyone to see your fancy lighting setup illuminating from within. The two flat radiator brackets, meanwhile, allow for liquid cooling systems on the top, front, or bottom (or more than one location), with room for up to a 420mm radiator per bracket.

The I/O panel includes USB-C and USB-A ports as well as controls for fans and lighting. If you’re measuring your space, this all comes in at around 12.05 by 25.16 by 25.63 inches. Overall, if you want the best combination of style and performance in a case, this is an excellent place to start.

Fractal Design Define R5

Fractal Design Define R5

With a sleek appearance and impressive built-in features — not to mention a low price — the Define R5 from Fractal Design is a great choice for just about any system builder. It’s not as flashy as some of its contemporaries but its wide configuration options make it a popular choice.

This case supports up to seven 140mm fans (two included) and provides dampening covers for the unused fan slots. It also supports an impressive amount of radiator options for water cooling.

Other notable features include slide-out trays for both internal hard drives, side-mounted SSD slots, dust filters for the front and bottom fans, and a quick-release system for the side panel. The only full-metal piece is the aluminum front access door.

The Define R5 ranges in price from $85 to $150 based on color (black, white, or titanium) and optional case window. The newer model — the Define R6 — adds vertical expansion slots and a USB-C port (10Gbps) for at least $20 bucks more.

Cooler Master Masterbox Q300L

If you’re on a tight budget but don’t want to sacrifice features for savings, then Cooler Master’s Masterbox Q300L is one of our firm favorites. Frequently showcased in our budget PC build guides, the Q300L is a mATX case with a gorgeous, compact aesthetic.

The Q300L doesn’t support full-size motherboards, but there’s enough space for full-size graphics cards, water-cooling radiators, full-size ATX power supplies, and plenty of fans to keep things cool. It also comes with magnetic dust filters and an I/O front panel you can place in six different configurations.

Overall, it’s an astoundingly effective case at a bargain price making it fiercely competitive with similar cases. The sub-$50 price seems almost impossible considering it uses steel, not low-cost plastic and aluminum.

Corsair Carbide Series 275R

There is something to say for affordable computer cases. You will have plenty of room left in your budget to get all the components you want for your build. 

This Corsair case is the right choice for you if you’re looking for a combination of aesthetics and affordability. The tempered glass panel case lets you show off the various aspects of your build, and the modern design and smooth lines give your computer a unique look.

This model includes built-in cable routing, steel drive trays that can hold both 3.5-inch and 2.5-inch components. The case features seven expansion slots you can use to customize it. The dimensions of the case are 18.1 by 8.3 by 17.9 inches.

This case includes two fans, though there is room for as many as six. You can also choose a 360mm front radiator, a 240mm top radiator, and a 120mm rear radiator to give your setup lots of cooling options. This case is an entry-level product that delivers a unique look. We think you will have plenty of space for your build, thanks to its roomy design.
