OK that's different, I thought you might have gone for the mobo recommended a couple weeks ago in the hardware forum. I can't tell much about the barebone without seeing or knowing what's in there. Unless it's something special, you must have both the main 24-pin power connector and the 4-pin (sometimes 8-pin) CPU power connector attached to the board. And then the small connectors/wires for LEDs and switches in the case. I suppose you've meanwhile found the SATA ports on the mobo for connecting the hard drive though?
