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.

Thanks (and to nwatson), but the ISP in this case is pretty loose about the 4U & power. In fact, my "4U" is just a table top right now because my Xserve case didn't fit. They don't seem to care at all about the power issue.
