Actually I would use the Super Micro Case
Written on the original Movable Type site and recovered from the Internet Archive.
SuperMicro SC933T-R760 (cse-933t-r760b) Extended ATX Rack-Mountable Case - Find, Compare, and Buy at DealTime. It is $850-$1000 just for the case. But well worth it! has tripple redundant power supply, 15 HD backplane. But I digress. The idea I am persuing is not building the ULTIMATE RAID, but building CHEAP RAID out of PC parts. This is definitely NOT a PC part.
