Welcome to a clean and simple OS. At home I run a supermicro dual 330 atom motherboard which I use as a combined cpu and auth serevr. I think this is a X7SPA-H-D525 though I honestly don't remember the part and don't want to open it up to look.
I have a raspberry pi as a terminal - this works wonderfully well booting in the time it takes me to move from the power switch on the wall to the keyboard. At work I have a single cpu/auth/terminal server which is a dull HP desktop box but it serves well enough. sheeva plugs also work well though I don't have one. -Steve
