I ordered a system with a single SCSI drive much as Don described. I just got a call from some dude at Dell who says that I need to add a SCSI controller! Since Dell's online configurator program let me select the SCSI drive, I thought the system had built-in SCSI support on the motherboard. Seems not. Dell wants $299 for a SCSI controller! (WTF!) If this is true, I think I'll go with IDE. Or cancel the whole thing -- I'm not sure.
