When we think of Mini-ITX motherboards, we usually think of VIAs EPIA range. However, as of recently Intel has introduced Atom, a very impressive low power CPU. Its power usage has plummeted and its performance per watt has increased, but compared to Nano it still can't handle the full load that a true CPU can. So until now it's been a bit of a compromise on the CPU power if you want a small form PC.
ZOTAC, one of the relatively new names here at TweakTown has come to the rescue by introducing form and functionality with their new Mini-ITX motherboard based around the nForce 610i chipset; supporting an LGA775 Core 2 series CPU.
