MOTHERBOARDSIntel Motherboard D975X BX2 Intel Bad Axe 2 (
5.5 bitcoins shipped in US.)
I originally called these mystery motherboards because it was not too clear exactly what the real "name" of this motherboard is, I believe I have found a spec sheet of sorts here:

Socket 775 (Accepts Core 2 duo, Core 2 Quad, Pentium Dual Core)
4x DDR2 667 and 800 mhz speed
4 Sata Ports
3 PCI-express full length card slots
2 PCI slots
From what I can read crossfire is possible between the top pcie either @ x16 and x1, or x8 and x8, and no matter what the third slot is x4 speed.
What I can tell you from personal experience is that I put three 5770 cards on the board with no risers for one mining machine, and I have one with a core 2 quad q6700 8gb of ram (4x2gb) and windows 7--I also plugged a usb3 pcie mini card into the third pcie "video" slot and it works, I guess people do this all the time but it was a first for me, lol!
I also read that these are a "stripped down" version of another board with a sata raid controller. I wouldn't doubt it it is hard to find info on it, but they work great! I should also have either a 2ghz or 2.1 ghz core 2 duo, or pentium dual core along with a coverplate for the i/o on the back of the motherboard for each available.
Infinity Dark P965 (
9 bitcoins shipped in US, also a socket 775 but fsb is 1333 capable with 2 full pcie and 2 short, they look like x1 to me )
1 ram plastic lock down thing is missing unfortunately from the infinity board but it hasn't given me any problems I have been able to properly seat ram without it...
CPUsCore 2 duo 2ghz
Core 2 duo 2.4ghz
Pentium Dual Core 1.8 ghz
RAMSome DDR2, will check
12 or so 667 ecc ddr2 modules
6 or so 1gb 800 mhz ddr2
Various 512mb modules
4 256mb of 533 (lol)
So thats what I've got! I bought all the same type motherboards together from someone locally who upgraded a whole bunch of workstations and apart from my checking one or two out for specs, and an odd sale here or there they not been touched since I acquired them. The other couple motherboards are mainly from desktops that I wanted the cases for or that I was planning on mining with and haven't yet. Feel free to post or pm with questions about the stuff listed here. I *don't* know exactly what I want for each so please feel free make an offer on what you can use. I'd be interested in bitcoin, local wa transactions possibly, or even trades for other pc parts. I plan on continuing to mine so if you are changing up your gameplan I might be interested in gpus (or ?) that you are not.
**edits** Changed things as it seemed prudent to do so, also added non-negotiable motherboard prices in bitcoins.
