Here is my HP xw8000. Big twin #Xeon socket 604 3Ghz processors, fairly strange 32bit architecture, #PCI-X slots. Takes up to 32GB RAM but only 64bit OSes will see more than 4GB of it, built in #ultra320 #SCSI controller, gigabit NIC, #AGP Video. Currently home to an #OS/2 #Warp 4.52 installation. Managed to get 8GB RAM.
