Mini Motherboards

[GhettoPeanut]

I've recently become a fan of building systems, pretty much i have the time and the money.

I've been thinking of building an ultra small system, and was wondering if anyone has done this, and what they chose for a mini motherboard

these guys seem to have a monopoly on the market
