I have this motherboard, with CPU (couldn't tell you what CPU from memory): http://reviews.cnet.com/motherboards/abit-nf7-s2g-motherboard/4505-3049_7-30... Could likely find some RAM to go with it. Socket A so not high spec, but might be a good replacement for a failed board.
I also have at least one Fujitsu Siemens Econel server with dead motherboard (PSU and CPU fine, I believe). Good solid metal cases with loads of drive bays etc, but not worth repairing. Should take standard motherboards if you can find one that the CPU fits relative to where the PSU is.
