I would also add that if you have printers which connect to your network cabling you can set them up as Hosts in server manager, the server box can physically be anywhere then.
I disagree with disconnecting one drive, perhaps you don't have protection from bus failure, but you do have protection from hard disk surface failure, which seems somewhat more prevalent.
Ideally you should have each drive as a master on seperate buses, surely your lovely new P4 box has 2 buses.
I have my sme box under the table the printers are on, which plug directly into the server, right next to the UPS, and it is mostly controlled remotely from a workstation, very rarely do I connect directly to the box, you can leave the keyboard disconnected if you want.
