Trust me, thats not an issue, hasn't been since 2000 (2000 = NT5.0, XP = NT5.1, 2003 = NT5.2, Vista/2008 = NT6.0 just fyi), I administrator a server with 16 physical drives.
Oh and thats like saying since Ubuntu is built on Linux, that it can't support a GUI, since the orginal "good" version of pure linux had no support for a gui .
Actaully, it didnt. ANd most admions I know, hate GUIs, coz, you really dont need anything more than a trident vid car ( 1 MB ):P And a really ugly text editir, Like Vi for example. ANd, than telnet in from another terminal.
