While you have 4U, how much power do you have allotted to that 4U? If you run a Q8400 with a 260w power supply for a 1U, you have a max load of 2.16A and probably an operational .9A-1.1A under normal load. Make sure you can run 4-5 Amps in your 4U. Many colo facilities allow 20 Amps per 44U so average consumption per U is just under .5A. andy @ interpromicro.com sells Supermicro equipment which run Debian without issues. Recent invoice 9/25/2009: Supermicro X7SBL-LN2, Q8400, 4gb RAM, 811T 1U dual hot-swap case, (no hard drives) Fedex 3day at $710. That motherboard does support AHCI in Debian allowing hotswap, sensors work, env/fan speed, etc.
