What is Mini ITX?
Mini-ITX is a small form factor for PCs that generally does not require as much power as other form factors. Other small form factors are TFX and Flex ATX PSUs, which may act as replacements for pre-built systems and proprietary cases from manufacturers, such as Dell and HP, as well as some of the more unique power supplies we stock in this category. These are all smaller than ATX and are often used in compact desktop PCs and HTPCs.
Why should I get Mini-ITX?
Because Mini-ITX is such a small form factor, it's ideal for building compact systems for use in your living, bedroom, or elsewhere that you want people to notice the display instead of your PC tower. At the same time you may not have a choice NOT to go with an ITX power supply - if you have a case and it's mITX, you have to go with this form factor.
