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...)
