Thanks for your thoughts, questions and input. About 2,000 dollars of the price is really for security/backup. Pricey, but you have to fell good about your back up. The t310 does have a hardware RAID controller. There won't be atape backup. Symantec actually has pretty easily configurable backup software...I certainly wouldn't use Symantec for antiviral/computer security. I'll let you know what I end up with. I'm also looking at wiring the exam rooms and putting stripped down, bare bones desktops in there. I tink Oct is the deadline for XP systems through Dell. That's another topic.
