SC450NX board in an Intel chassis. Its so clean because it appears to have been a hot spare. Not a hint of dust anywhere inside. Behind the covers over the two remaining 5.25" bays are 2 9.1GB drives connected to the onboard SCSI controller. 4 of the 6 hot swap bays are occupied by 18.1 GB drives connected to a PCI RAID controller. The CPU installed is a PIII Xeon 550/2MB. All of the voltage regulator modules are installed though, so I suppose I could run 4 procs if I wanted. If you look closely only two DIMMs are installed. That is what is keeping me from running it right now. I'm gonna pick up some RAM on ebay soon and see what (if anything) is installed on it. I know its rather old, but still should be a fun project. Not sure what I'm gonna have it do yet though.
