I'd probably go $1,600 on that one, mainly because of the added SCSI and RAM. Actually, I'd probably go more myself, but I'm telling you that if you have to go $1,600 to get that one, it's worth it.

$1,450, maybe $1,500. You'll want to stick more RAM in there, but that can be had cheap at Crucial.

Buy that and then add more RAM (2x512MB) and you will be a happy camper.
