All About The Mini-ITX

Back to Glossary

What is a Mini-ITX?

Developed in 2001 by VIA Technologies, Mini-ITX is a small motherboard configuration. The motherboard measures at only 6.75 inches by 6.75 inches. It was originally popular for home theater computer systems because their fanless design ran silently without distracting from cinematic viewing. With low power consumption and a compact size, mini-ITX are made to fit in devices such as automobiles, network devices, and small robots. They are also often used in commercial and embedded PCs. Mini-ITX have just one slot for a graphics card and two slots for RAM.

Advantages of Mini-ITX

One of the main advantages of the mini-ITX is its compact size—3 mini-ITX is about the size of 1 standard mid-tower. Not only do they save space, mini-ITX are also lighter. They are generally cheaper in price and there is a large variety to choose from. It is easy to find rugged and fanless designs. High demand for the mini-ITX means longer lifecycle without having to replace.

Disadvantages of Mini-ITX

While the size is one of the mini-ITX’s greatest advantages, it is also the cause of many of its disadvantages. Because of the compact size of mini-ITX, not all graphics cards will fit. There is more heat from the components having to run in a smaller space. Due to the limited slots available, there is less room for expansion than a traditional tower computer. The smaller space may be especially hard for someone with larger hands to work in, and cable management is a must.
