although you can now run all components on one cpu server, it's still best to scrounge the extra machine to keep the file server and cpu server separate, and to run a limited set of services on the file server. i don't see why it can't be the auth server as well. i put the file servers on a cheap UPS as well, to reduce anxiety about scrambled or lost data in venti archives (although on wednesday morning i bumped into someone else in a shared machine room who was crouched down changing some batteries that had gone bad on their UPS).
