Via Motherboards
These little motherboards come in two versions, the 533 Mhz fan-less Via Eden ESP 5000 processor version and the 800 Mhz Via C3-E processor version. The boards are exactly the same otherwise.
You can see the small footprint of the Mini-ITX form factor is 1/2 the size
of the traditional motherboard.
