Pico-ITX mainboard form factor is a complete x86 mainboard

It is a race to the bottom, in form factors, the laptop / handheld market is being encroached by commodity mainboards for the desktop and developer community. I am working on a Mini-ITX project right now. It could be so much smaller!

VIA Technologies, Inc.

The Pico-ITX form factor leverages VIA's focus on enhancing power efficiency, thermal management and feature integration at both the silicon and platform levels, and has been designed specifically to be powered by VIA's energy efficient processor platforms, such as the VIA C7 or fanless VIA Eden processor, and based around one of the new breed of VIA's system media processors, all-in-one digital media IGP chipsets such as the VX700, which combines core logic, multimedia, connectivity and storage technologies within a highly integrated single-chip package..
