I've had good luck with options from SuperMicro and the configure-it-yourself stuff at TigerDirect/GlobalComputer (forget what brand they sell it under). Also, you'll often find a huge price difference between a 2U unit and a 1U unit of the same specs (2U being cheaper...). Might be worthwhile to spend a little more on a 2U unit (mostly for more RAM) and get more bang for your buck and run VMWare on it. That way it could have a couple of different recovery images on it, or possibly room in the chassis for mirrored drives or something.
