We also like this case because while it’s great for beginners, it can be customized into a high end PC.

The Corsair Obsidian series 1000D is a behemoth of a PC case. Considered a super tower at 27.3 inches you’re going to get a lot of room to add many components to your gaming PC. How much room exactly? You can install up to 18 fans, 4 massive radiator cooling systems, 5 2.5″ hard drives, 6 3.5″ hard drives, and 6 USB ports. The 1000D is so big you can comfortably house two complete PC builds within it for a seamless streaming and gaming experience. If having two computers doesn’t catch your fancy, you will still have the freedom to add as many graphics cards as you could possibly need along with as much memory you could need.

With tempered glass all around the case, you can have a real field day when it comes to creating customized lighting. In fact, the case comes with a built in lighting control. Of course, with such a behemoth, price is going to be higher. The Obsidian 1000D goes for about $500 making it by far the most expensive micro ATX case. We only recommend it for people who are serious about creating a very high end PC or have a desire to create two builds within the same casing.

How to Buy the Best Micro ATX Case

When it comes to buying any PC case, there are several factors you need to be aware of before making your purchase. Being impulsive can lead to you having parts unable to fit neatly inside your case, delaying you from finally powering on your system. Buying the other components of your PC should be done in tandem with your case so that you make sure everything will eventually fit. Here are the most important factors:

Size and Space

When it comes to buying a Micro ATX Case the most important factor is size. You are buying a micro atx case specifically because you need a case to hold your micro atx mother board. You need to make sure however that your other components are going to also fit within the case. Before buying make sure you know the size of your video cards, cooling system and power supply.

Cooling System

The cooling system is another aspect that can’t be ignored when you are on a quest for a top micro ATX case. If you have built a PC before, then you probably have a good idea of how much cooling you need for the type of gaming you do. If you’re new to building a computer, then you need to take a moment to assess what it is you want out of your system. If you are planning on overclocking and running everything hot, then you’re going to need cooling. All of the cases we rank above are capable of housing liquid cooling systems but not all of them will be able to provide enough cooling for serious overclocking.

Cable Management

One more thing you should consider is the cable management system. A good cable management system helps you keep all your component cable in the right place which leads to a clean build. The cases we curated above all have good cable management for the most part. Not every case you may come across however will have the internal design conducive to good cable management. If you select one of those cases, you will need to be more diligent in your planning while building the PC.

Extension Bays

The number of extension bays are important when it comes to memory and accessorizing your build. While a more minor issue and one that mainly concerning hard core gamers, you should always be cognizant of the number of extension bays. Most cases will come with 2, 2.5″ or 3.5″ bays which can store two hard drives (usually an HDD and SDD). Some more intense cases however will have multiple bays to hold multiple drives as well as temperature readouts and fan controllers.


Good cases will provide good noise insulation. The cases we recommend above are all decent to great for noise however that will not be the case for every fan. Aluminum and metal will generally insulate best. The number of fans you run as well will be ultimately be determinate in how quiet your system is.
