What is Mini ITX Form Factor?
I think I should start this review by explaining just what MiniITX form factor motherboards are. The form factor was originally proposed by VIA to be an ultra small form factor, smaller than the FlexATX and MicroATX form factors that were the smallest at the time. The original MiniITX boards were feature rich boards with a CPU soldered onto the board. This was cheap to produce as there was no discrete packaging cost for the integrated processor.
The specifications of the MiniITX form factor state that the board may not be bigger than 170mm x 170mm. As you can see this is tiny when compared to the normal ATX standard.
VIA also aimed to have very low heat output from the MiniITX so it would be more suitable in systems like the Hush. Some of the VIA EPIA series models are passively cooled but unfortunately these are the less powerful models. The higher powered boards require a small heatsink with a 40mm fan and these fans can often be quite noisy so Hush set out to combine the faster EPIA models with a passive cooling system.
