This case was off an old P2-350 Server from approx 1993. It is built like nothing I have seen apart from IBM AS400 servers. Solid machined aluminium, copper connectors, stainless steel fittings. A real work of art. I simly modified it for taking my Asus M4A785D-M Pro motherboard and PSU.
ps. The Drobo is a version2 800 Firewire, with 3TB of storage and the backup system for the website and all the files.
