I've got a small home office with only a few computers that I'd like to back-up automatically. Windows Home Server looks to be a promising solution. The few pre-packaged models I've seen are quote small and consume very little power which is a big plus for me since I'd like to leave it running all the time for photos and music. I've already got a local DC to unify the logins and manage updates, but I'd like to retire it since it sucks a lot of power and home electricity rates are significantly higher than commercial rates.
So the question is, can I run a Windows Home Server as a DC?
