Got this running while board was down. Lets you pxe boot into Linux with Boinc running. Works real good. For those of us that want just a bunch of servers without monitors or lots or hard disks this is the way to go. The biggest problem I had was getting my NFS setup, but now I can just put a bunch of motherboards on boxes, like I saw in Dr Pop's pics and boot. Just need a CPU, motherboard, memory and PSU to make a crunching machine.
