The best PC cases are there for more than just showcasing the epic RGB lighting on your internals. While many computer chassis come in awesome designs meant to show off your components and their RGB lighting or flaunt your gaming PC’s prowess, they’re first and foremost meant to shelter and protect those internals. 

PC cases are designed to keep dust and debris away as well as ensure that your processor, graphics card, and motherboard are getting more than enough ventilation to keep them cool and working optimally. So, when you’re building your own PC, regardless of whether it’s for your new work-from-home setup or for gaming, choosing the perfect PC case is just as vital as choosing the right components for your needs.

We found the best PC cases 2021 has to offer, ones that offer excellent ventilation, a great design, and even additional empty bays for future-proofing. Check out our list and the included price comparison tool so you can find the best prices available.

Mobo compatibility: ATX

I/O: (1x) USB 3.1 Type C, (2x) USB 3.0, (1x) Audio in/out
Reasons to buy
+Incredibly stylish and open design+Great out-of-the-box airflow
Reasons to avoid
-Attaching and removing most removable internal pieces is frustrating

A hulking glass beast is what you’re getting with the Corsair iCue RGB 5000X whose offerings include good cooling – thanks in large part to its mesh coverings around the top and bottom panels, a lot of space for efficient building, and three Corsair RGB fans. And, it delivers all those while looking incredibly sleek, albeit massive. It might be a bit pricey for some folks, but for those whose top priorities include airflow and space, it’s worth the price.

2. Fractal Design Meshify-C

The best mid-tower PC case

Specifications
Form factor: Mid-tower
Dimensions: 395 x 212 x 440mm (L x W x H; 15.6 x 8.3 x 17.3)
PSU support: ATX
I/O: 2 x USB 3.0, 1 x HD audio in/out, power button, reset button
Includes: 2 x Dynamic X2 GP-12
Reasons to buy
+Freshly designed in multiple ways+Reasonable price
Reasons to avoid
-USB 3.0 cable is too short Front-PSU dust filter is hard to remove

It is extremely rare to see any PC case that even vaguely resembles the Fractal Design Meshify-C. Given that the front of the case is entirely made of a mesh material sectioned off into an array of polygonal shapes, the Meshify-C has a unique style – without compromising on function. With two fans pre-installed, cooling is (forgive us) a breeze, even if the Meshify-C is held back by a number of obstacles.

3. Nanoxia Deep Silence 4

The best Micro ATX PC case

Specifications
Form factor: Small form factor
Dimensions: 380 x 200 x 480mm (W x H x D; 15 x 7.9 x 18.9 inches)
PSU support: ATX
I/O: 2 x USB 3.0, 1 x USB 2.0, HD audio in/out, power button, reset button, two-channel fan control
Includes: 2 x 120mm fans, 2 x modular HDD cages for up to five hard drives
Reasons to buy
+Low-noise+Onboard dual-zone fan controls
Reasons to avoid
- Not many extras 

As its name suggests, the Nanoxia Deep Silence 4 has the sole purpose of being quiet as a mouse. This silence-focused case is a well-balanced Micro ATX chassis that’s affordably priced, without sacrificing room for expansion. That’s right you can fit even the biggest, most powerful graphics cards in the Nanoxia Deep Silence 4. The fact that you will never hear it go above 30 decibels is just icing on the very taciturn cake.

4. NZXT H200i

The best Mini-ITX case

Includes: 1 x Aer F120 Case Version top fan, 1 x Aer F120 Case Version rear fan
Reasons to buy
+Built-in Smart Device RGB control+Adaptive noise reduction
Reasons to avoid
-Slightly pricey

Every single day mini-ITX gets more popular, and closer to toppling Micro ATX. And, it makes sense – why not spring for a small computer that can get just as much work done as a full tower? NZXT’s new H-series case line manages to integrate a ton of the same features as its Micro ATX and mid-tower equivalents, with mesmerizing, built-in and smart device-controlled RGB lighting and an adaptive noise sensor that sees improvement only by way of the Grid+ V3 fan controller.

5. Phanteks Evolv Shift X

The best home theater PC case

Specifications
Form factor: Small form factor
Dimensions: 170 x 650 x 274mm (W x H x D; 6.7 x 26.1 x 10.8 inches)
Mobo compatibility: Mini-ITX
PSU support: SFX, SFX-L, ATX (160mm max)

Includes: 2 x 140mm fan, 1 x power supply cover, 1 x pump bracket, 2 x SSD bracket, 1 x PCIe x16 Riser cable, 1 x 8-pin CPU extension cable
Reasons to buy
+Plenty of room for beefy components+One-of-a-kind aesthetic
Reasons to avoid
- Massive for Mini-ITX

When you first look at the Phanteks Evolv Shift X, it looks more like a sound bar than one of the best PC cases, but this helps it vanish into any living area or studio setup. It’s flexible to the point that it looks natural placed under a TV as it does on a desk, next to one of the best gaming monitors. It may only be compatible with a Mini-ITX motherboard, but the Phanteks Evolv Shift X offers tons of space for components and liquid cooling loops. If this case is  a little large for your preference, you can get the smaller Phanteks Evolv Shift for easier management.

6. Fractal Design Define R5

The best silent PC case

Specifications
Form factor: Mid-tower
Dimensions: 232 x 451 x 521mm (W x H x D; 232 x 451 x 521 inches)
PSU support: ATX
I/O: 2 x USB 3.0, 2 x USB 2.0, audio in/out, power button with LED, HDD activity LED, reset button
Includes: 2 x Fractal Design Dynamic GP14 140mm fans, velcro straps
Reasons to buy
+User-friendly (and handsome) design+ Affordable price
Reasons to avoid
- Definitely not tool-less

Fractal Design wins again with the Define R5, yet another mid-tower case with a gorgeous aesthetic. The metallic and blue LED-lit face of this case is simple, yet elegant, and is accompanied by noise dampening materials throughout its interior. In spite of the detachable ModuVent panels and drive trays not being toolessly accessible, it’s incredibly easy to build a system inside of the Fractal Design Define R5, plus it’s not as expense as you’d expect from a PC case with such a pretentious name, either.

7. Cooler Master H500P Mesh

Includes: 2x 200 x 25mm RGB fan, 1x 140 x 25mm fan
Reasons to buy
+Great airflow+Gorgeous RGB lighting
Reasons to avoid
-Not as big as other full towers

Cooler Master is kind of known for, well, cooling things – and the Cooler Master H500P Mesh is evidence of how it got there. This beautiful RGB-packed case has plenty of room for airflow, even accommodating up to 360mm radiators on the top and front for when you really want to take your cooling to the next level. Add on top of that the RGB lighting and tempered glass side panel and you have the potential to build something beautiful with this case. Go for it.

8. Corsair Carbide Series SPEC-04 Tempered Glass

The best budget PC case

Specifications
Form factor: Mid-tower
Dimensions: 492 x 201 x 433mm (L x W x H; 19.4 x 7.9 x 17 inches)
PSU support: ATX
I/O: 1 x USB 3.0, 1 x USB 2.0, 1 x headphone port, 1 x microphone port, power on button, reset button
Includes: 1 x 120mm LED front fan
Reasons to buy
+ Attractive price + Very aesthetic 
Reasons to avoid
- Only includes 1 case fan 

If you’re looking to save a few bucks, while still getting one of the best PC cases, look no further than the Corsair Carbide Series SPEC-04 Tempered Glass. Not only does it have plenty of space for airflow, it also has a deceptively large amount of space for future expansion, meaning that even at this low price point, you won’t have to worry about fitting a full-sized graphics card. And, when you’re done building, the tempered glass side panel will allow you to show off your handiwork.

9. Antec Cube

The best PC cube case

Specifications
Form factor: Small form factor
Dimensions: 365 x 250 x 460mm (H x W x D; 14.4 x 9.8 x 18.1 inches)
PSU support: ATX
I/O: 2 x USB 3.0, I/O button, audio in/out
Includes: 1 x 120mm rear exhaust fan mount
Reasons to buy
+Ample space for power and cooling+Integrated fan controller
Reasons to avoid
-Wildly expensive-Less than satisfactory performance

The Antec Cube is without a doubt the best PC case for you Razer fans out there. While Razer hasn’t made its own desktop PC (not yet, anyway), you can build a Mini-ITX gaming PC, pretending it’s a razer product. You see, Antec partnered with Razer to bring its signature green-infused flare to the Cube, a small form-factor chassis. Complete with a deceptively high amount of space for future expansion, the Antec Cube is also compact enough to travel with.

10. Thermaltake Core W200

For a fully kitted-out setup, and then some

Specifications
Form factor: Super Tower
Dimensions: 677 x 475 x 678 mm (26.7 x 18.7 x 26.7 inch)
PSU support: Standard PS2 PSU x 2 (optional)
I/O: USB 3.0 x 8, HD Audio x 2
Includes: Transparent Window, 10 expansion slots
Reasons to buy
+Can house a ton of stuff+Very customizable
Reasons to avoid
-Not cheap

The Thermaltake Core W200 might not be the cheapest, but it may just be what you need if you need a piece of kit with all the necessary (and some perhaps frivolous) trimmings while still having more than enough room to expand in the future. This super tower has room for more than twenty drive trays and up to ten expansion slots – more than enough to technically have two PCs in it. And, if that doesn’t seem versatile enough for you, it also has a dismantlable modular design boasting removable drive racks and freely interchangeable SSD/HDD cage sections. All that comes at a (steep) price, but it’s well worth it if it’s exactly what you need.

What is the best airflow PC case?

If you only care about keeping your PC components cool without investing in pricey and complicated liquid cooling setups, the Cooler Master H500P Mesh should be at the top of your list. Plenty of open space, and more room for fans than many other mid-tower PC cases, and it looks good to boot. 

What is the most overkill PC case

In the world of PC gaming, we all love going above and beyond what anyone could reasonably need in a gaming rig, and that all starts with the PC case. Cases like the Corsair Obsidian 1000D, which can fit two whole PC builds are exactly what to look out for when looking for an overkill PC case.

Which case is best for a gaming PC?

Honestly, pretty much any case on this list is going to be an excellent pick for a gaming PC. But you should consider what you're going for with your build, whether you want a ton of RGB flair like the Corsair iCue RGB 5000X, a lot of airflow like the Cooler Master H500P Mesh or something small and portable like the Antec Cube.

The best part of picking a PC case, like with anything in PC gaming is that you have so many choices that will be absolutely amazing.
