What is an ATX Case, and What Does ATX Stand For?

ATX stands for Advanced Technology Extended. ATX is a motherboard specification that highlights some essential components of the motherboard, such as dimensions, connection ports, I/O ports, and power supply ports. A computer case is also known as computer chassis. It contains most parts of a computer or system unit. The term "ATX" means that a particular case is specifically designed to fit the components of an ATX motherboard. 

If you are using this type of motherboard, you should pick an ATX case. For gamers and computer users who need a small nook for their computers, choose one of the smallest ATX cases.

What Are ATX Case Sizes?

In technical terms, PC cases are usually referred to as three form factors: ATX, Micro-ATX, and Mini-ITX. Depending on the size and dimensions of the gadgets placed inside your system unit, an ATX case may be the right choice. A standard ATX case is 12 x 9.6 inches, and a Micro-ATX comes in at a size of 9.6 x 9.6 inches. Meanwhile, the Mini-ITX measures 6.7 inches square, in size. When choosing a case for your system, keep in mind that a case for a larger motherboard would be relatively more significant in size compared to an ATX case for a smaller motherboard.

Can an ATX Motherboard Fit in a Micro-ATX Case?

An ATX motherboard can easily fit in a micro-ATX case. The only downside of this will be that either your motherboard case will be too loose or too tight. So, it is better to have an idea about the fittings of your case and the dimensions of your motherboard.

What is the Difference Between ATX and Micro-ATX?

The main difference between ATX and micro-ATX is their form factor. In simpler words, their size. Generally, ATX has a rectangular board measuring around 305mm. On the other hand, micro-ATX comes in more of a square shape, roughly measuring up to 244mm. You must choose per your needs.

Is ATX Better Than Micro-ATX?

To answer your question shortly and honestly, micro-ATX is the best choice as far as cases are concerned. If you are looking for a compact PC, only then, go for the mini version. On the other hand, if you are looking for more PCI-e slots, then go with the ATX version. It all comes down to your needs and requirements. 

A Micro-ATX Motherboard Will Fit Into a Case That Follows What Minimum Standard?

One of the most important requirements is to make sure that the ports of the case that you are buying, along with synchronization with all the cables and wires that are important, can attach with your motherboard and system unit. If this is sorted out, the rest will fall into place.

What Size is ATX?

If you are asking about a general and mostly used ATX, then a normal ATX motherboard is twelve inches wide and approximately nine inches deep. But you might find variance in sizes to a certain extent, as well. It is advised to do thorough research before settling on one case or even motherboard. 

Which is Smaller, Micro-ATX or Mini-ITX?

Mini-ITX is both short in height and length when compared to micro-ATX. Choose the one that is best suited to your dimensions. Most medium to small-size cases will easily accommodate normal to small-size motherboards. This is also one of the advantages of these cases, in particular.
