In fact, many professionals now rely on highly demanding software, which is why they also tend to build their computers from scratch. The first step of that process is buying the best micro ATX case you can afford.

What Is a Micro ATX Case?

As we already explained, a micro ATX case is a case which supports micro ATX motherboards. Most of the time, the people who are interested in micro ATX cases are gamers. That is because many video games, especially the newest releases, require exceptionally strong computers with incredible performance values in order to run smoothly.

Passionate gamers dislike being limited by what typical computer stores have to offer. Most of these pre-made configurations are way too expensive for their value. Therefore, many gamers prefer to build their own PCs from scratch, starting with a computer case.

The group that used to be mainly gamers now includes designers, video producers, and all other kinds of professionals. Now, although setting up your own PC can generally turn out to be cheaper than buying a pre-made one, the final price depends on the buyer’s choices. Generally, the goal is to find well-functioning parts which are not overpriced. That is why it’s important to get the best micro ATX case your money can afford.

The models presented in this guide offer a good ratio of quality and price. However, everyone should know how to assess the particular features in order to buy exactly what they need.

What to Look For in Micro ATX Cases

Here are all the things you should take into consideration if you want to pick the best gaming case for you.

Available space

The best mATX case offers you plenty of empty space on the inside. The amount of free space defines not only the number of parts you can install but also the type. This criterion is the first thing to check for when buying a case. Most users already know what kind of PC they want to set up, so they seek cases which match these builds. Other than the HDDs, SSDs, graphics cards and other essential units, do not forget about coolers, cables, and various secondary parts.

Options for cooling

Most people build their own PCs because they need a powerful, high-performance machine. Naturally, such a PC will tend to heat up very quickly. That is why it’s absolutely necessary to pay attention to cooling options. The best mATX case will allow you to install water cooling systems. Other than fans and coolers, an important cooling system is the airflow. Now, that aspect depends only on the shape of the case, which is why it’s best to choose carefully.

LED lighting

Not all mATX cases have LED lighting. The ones that do are somewhat better for it. While this is not a crucial part of a good PC, having LED lights is both practical and aesthetically pleasing. Users building their own PCs will appreciate being able to closely examine the interior of the case with proper lighting.


The most functional micro ATX cases are often the smallest micro ATX cases too. Every user wants a case which is as small as possible so that it doesn’t take up a lot of space. At the same time, a case should have enough room on the inside to house all the components. If designed properly, a micro ATX slim case can still host many different parts.

Cable Management

The better micro ATX case is likely to have a way to handle excessive cables. Again, those who buy pre-made computers don’t really have to think about this issue. However, users building their own systems usually like to achieve a simple, clean layout. Keep an eye out for features dedicated to managing cables in various models you come across.


Most gamers prefer function over form. However, those willing to invest a lot of money into building a PC can expect great looks in return. Fortunately, the best mATX case is often the best-looking one.

Wrapping up

While a micro ATX case is not the most important part of a PC made from scratch, it certainly is an important starting point. These cases are not cheap, and it is essential to get the model that matches your ideas. We believe that the Corsair Carbide Series SPEC-M2 has everything a micro ATX case should have. However, gamers on a budget can find many other effective and reliable cases. Hopefully, our guide has provided you with a good starting point for your search. Good luck!
