Beware. The dual Xeon 1U (2.4 Ghz) I saw measured ran 125W *idle*. Run a few processes of burnMMX and burnP6 on it and the power used will double. 250W for each 1U. The electricians I've talked to don't realized the size of the possible change and seem willing to plan based on measurements of the "current load" without knowing if the machines are idle or loaded. > > There's marginally more heat coming from the hard disk and power > > supply, but it's minimal. The air output temperature will also increase. I measured a change from about 80 F to 99 F (input was about 72 F).
