Man...I'm SO going to get this and replace my current Linux server. I have a 64-bit PCI SCSI controller card in my current box that's sitting in a 32-bit slot...I'll finally have it where it should be. Bad news is that they charge tax, raising this another $20 or so for me, but, still, $290 for this thing is incredible.
EDIT: With the PCI issues everyone is talking about - I need to use this server as a router, meaning I'll be adding a NIC in for the extra port. I take it I can't just drop in a regular D-Link/Linksys/etc. NIC? Or is this not as much of an issue as with the sound cards?
