People are still feeding their gear with AC? Save on PS inefficiency, and feed direct 12/5vDC to the servers. Save space, save power, save cooling.
What does that do to customer equipment choices? I've got a quarter acre of boxes that I know want 12/5vDC inside the case, but that's not an easily available option from the vendor - most of the time the only option is autoswitching 120-240DC with your choice of power cables. (If anybody has a good TCO analysis for doing this with Dell/Sun/IBM/Apple servers, I'm willing to listen...)
