Just bought a new motherboard to stick in my server.
It's a Gigabyte GA-GC230D with an integrated Intel Atom processor.
The thing is tiny ! The yellow slot is a standard DDR memory slot. I have put a pen and a quid coin in the picture to demonstrate how small this thing is.
Anyway main reason for buying it is to reduce the power usage and heat from my server and save a few pennies in electricity and let me leave it on longer.
Will post up details of it installed later.
