What is an ATX Case?

ATX stands for Advanced Technology eXtended, and it is a configuration specification for motherboards, which was developed by Intel in 1995. An ATX case is a protective case for your hardware so you can contain all the components of your computer in a safe enclosure.

They are usually designed to fit the ATX motherboard and all of its components so your computer can perform efficiently without being damaged. Most of the ATX-compatible cases accept Micro-ATX or Mini-ITX boards. A big ATX motherboard roughly measures 12”x 9”, which means there’s a lot of extra space available.

Micro-ATX vs. ATX Case - What’s the Difference?

There are two common form factors for desktop computers: Micro-ATX and ATX. Let’s go over the differences of these two before proceeding with the reviews:


Micro-ATX, as the name suggests, is smaller than the ATX, and hence, has a smaller case. ATX measures 305 mm x 244 mm, whilst the micro-ATX is more square-shaped, which means that it keeps the width of 244 mm, but has a length of 61 mm.


Expansion Ports

Micro-ATX has lesser expansion ports than the full-sized ATX motherboard. Micro-ATX boards have three expansion ports, with four at maximum, whilst ATX motherboards have five expansion slots. However, some manufacturers compensate for the lack of expansion ports with additional features such as sound, graphics, or network capabilities.

Drive Bays

a micro-ATX form factor has fewer drive bays than the full-sized ATX board. This is not a big deal if your computer has only one or two hard drives but can be a problem if you have a lot of optical drives on hand and want to implement RAID. If you want more room to accommodate any future expansions, a micro-ATX board is not a suitable option. Micro-ATX can fit inside the ATX case, but not vice versa.

How to Choose a Micro-ATX Case

Before choosing a micro-ATX case, here are a few main considerations to keep in your mind so you know exactly what you’re looking for:


Micro-ATX cases come in a lot of different designs, colors, and prices. You must decide the budget you are willing to spend on the case and rule out all of the options that come above the budget. If you’re willing to stretch the budget, depending on the model or features, then that is up to you, but cases can range anywhere between $50 and $150.


You need to look for the kind of case that appeals to your aesthetics. The cases come in many different sizes, colors, materials, as well as designs. There are some cases that come with LED lights, while others are sleeker and simpler. You need to find the one that suits you.

Cable Cuts

Look for a case that comes with cut-outs in the tray of the motherboard, as this will allow you to fix your cabling from the back of the case. Some budget cases have simple cut-outs for the cables, while some mid-range or higher range cases come with rubber grommets so the setup looks tidier.
