It probably doesn't run at 100W, although I'd be quite curious to know whether someone actually measured the consumption, since I have the HP version of this.
The reason why I don't expect it to draw as much is because I have an 8-core xeon with 2x10k RPM + 4*7200 RPM drives, a dedicated raid card, integrated BMC, and it reports ~100W power draw when booting up. When sitting around doing nothing but with the drives spinning, it reports a draw of about 80W.
edit: The BMC alone draws 11W, judging by the reported power consumption when the server is off, but plugged in.
