Looking to build a slick new gaming PC? As you’re looking through the components you need, you might be forgetting a crucial part: the case. The case sets limits on the parts you can combine and can affect how your build looks, runs, and stays cool. So finding a great PC case is critical.
Let’s break down the best white PC cases across all three form factors: ATX, mATX and mini-ITX.

What Kinds of PC Cases Are There?
There are three primary types of PC form factors (the size or physical arrangement for a computer). These sizes can indicate what size of motherboard you can use, where certain internal components might rest, and what ports are available for both components and attachments. Speaking of motherboards, if you’re looking to make a white PC build then you’ll want to get a white motherboard as well for continuity.
ATX
Standard ATX PC cases will have enough space for motherboards sized at around 12” x 9.6”. The biggest difference between micro-ATX (also called mATX) motherboards is an extra couple of inches of height. This gives standard ATX motherboards more PCIe lanes, so they can run multiple GPU cards or use multiple PCIe devices.
Aside from being able to fit ATX-sized motherboards, these cases also usually come with more fans (or spots where you can fit fans and cooling units) and more aesthetic ports. So you can add more lights and whatnot to your case for added personalization. ATX cases (also called mid cases) come with more 5.25” drive bays, usually between two and five. You’ll get more expansion slots on average, too.
Basically, ATX-sized PC cases are better if you want to fully deck out a gaming PC or if you’re interested in upgrading your build as time goes on. There’s no doubt that the highest power and top-tier gaming PC needs an ATX case.
Micro-ATX
Micro-ATX cases are suitable for mATX or below-sized motherboards. These are also called mini towers. They’re a little more affordable than ATX cases and are better if you’re on a budget. This is why many people looking to build a budget gaming PC go with an mATX tower instead of a full ATX tower.
There are additional benefits, like the fact that mATX towers can still take a good number of components and have plenty of slots for expansions. You’ll usually get a couple of 5.25” drive bays, a handful of expansion slots, and the ability to fit one or two graphics cards. They’ll also have room for between two and four fans on average.
With these, you can still build a decent gaming rig using one of these towers without spending nearly as much cash. Many of them even include lighting ports for aesthetic fun.
Mini-ITX
Mini-ITX cases are the absolute smallest you can get, and they’re only suitable for mini-ITX motherboards. As you might expect, you don’t have nearly as many ports or slots for components. Most only come with a single 5.25” drive bay, and you might not get any 2.5-inch drive bays. Still, you should have at least one or two expansion slots and room for a single graphics card. Be sure to check out fan slots, as some mini-ITX towers only have one fan, which can make cooling your components difficult.
These do have a few benefits, however. They’re much more portable and can save you a lot of space if you don’t have tons of room for a rig. If you aren’t interested in high-powered gaming capabilities, you can use this tower to build a home theater PC or something for your kids.
One last note: ATX-sized PC cases can fit any type of motherboard. So you can always combine a larger case with a smaller motherboard even if you can only afford an mATX or so-sized one. This allows you to upgrade to a larger motherboard later if you want to build your PC up over time.

It features a tempered glass frame so you can see the interior from more angles than most other gaming chassis allow. Not only does it allow you to show off your rig to anyone who stops by, but it’ll also help you see when it’s time for a good cleaning session (particularly if your rig is down low where dirt and dust accumulate over time).
The tempered glass window is pretty strong and can reduce noise from the components, too. It features three placement layouts for various components. This allows you to customize how the rig is set up according to your preferences. You can even set up your graphics cards vertically with a special bracket.
