12 Best Micro ATX Case In 2021

Several Micro ATX Cases are available in the market, but choosing one the best and the most compatible can lead you to research. But, today at Detective Gaming, we have extensively researched and gathered the best micro atx case that you can buy for your build.

Micro ATX can be of different sizes and for different needs. But, every micro atx case has a specific dimension of supporting 9.6 x 9.6 Inches (244 x 244 mm) micro atx motherboards, so whenever you buy a micro atx case, those will be supported dimensions.

These Micro ATX cases come in various sizes and types. When you think about assembling a PC, you don’t only consider the motherboard but also the components going into the motherboard. These cases will hold the PSU, Motherboard, GPU, SSD’s, HDD’s, etc.

With all the perfect assembly, you will also have to give a thought towards ventilation and looks. Most of these micro atx cases will support more than one fan. But the size of the fans supported can be different. Most of the cases do come with fans, so you don’t have to churn more towards buying new ones.

Few of these micro atx CPU cases support RGB. But until then, let’s have a look at the list of micro atx tower –

Best Micro ATX Case 2020

Most of the budget micro atx cases come in between $50-$100. Although there can be more expensive or mid-range cases available, you can buy the best-looking RGB micro atx case under or near about $100.

Cases don’t have to cost much and come with the decent build quality. Brands like Cooler Master, Thermaltake, Corsair all manufacture CPU cases.

We have compiled the list of 12 best micro atx case –

1. Cooler Master MasterBox Q300L Micro-ATX Tower 

The first micro atx tower that we would recommend would be Cooler Master MasterBox Q300L. It does not only have the best build quality but is the minimalistic looking m-atx case. It is the lightest PC tower in the segment weighing just 0.4 Kg.

There are two removable magnetic dust filters up top and in front, which are great additions for keeping the PC cooler. Cooler Master MasterBox Q300L is transparent on both sides, and internals is exposed visually.

A single fan is included in the box. Sadly that isn’t any RBG or color fan. But, I hope you replace it will newer fans. Although there is plenty of airflow within the case, it also supports 5 x 120mm or 140mm fans. Sadly, you cannot add fans at the top, but it should not be a problem considering there is a fascinating amount of cooling done by the fans.

If we talk about the space, there is plenty; your PSU stays at the bottom and should not be a problem with your normal PSU. Although it is a micro atx case, it can support normal atx PSU.

If you are looking budget micro atx case, Cooler Master MasterBox Q300L is the one to go for.

Oh, and it can go both ways, vertical and horizontal.

Cooler Master MasterBox MB320L is the next case I would suggest for your micro atx build. As it comes from the same company, it has majorly improved design and better fans. There are 2 fans included in the box, whereas both are installed in the front and ARGB (Alpha, Red, Green, Blue).

The dual 120mm ARGB fans can be connected to the motherboard allowing you to customize and control the lighting-color system.

The front panel is transparent so that you can look at the gorgeous fan lighting, and there are vents at the side for airflow. Also, this micro atx computer case supports fans at the top; to do that, there is a mesh at the top for more than sufficient ventilation.

Cooler Master MB320L supports mini & micro atx motherboards, so you won’t have any problem selecting any. This micro atx tower supports most of the PSU & GPU and would not give any space problems. In fact, you can build a liquid-cooled CPU in the same case.
