I ran it for awhile too, on my laptop. I think that was back in my post-Vista try-all-the-other-options-out-there days, as I cannot remember what advantage it gave me that XP didn't have, but I do remember it being a pain to get set up for DirectX and other things that you generally wouldn't use on a server. Still, it did look cool to see my laptop displaying its "Windows Server 2003" screensaver in the library.
