Behold, the Duct Tape Server
, which is not so much a case mod as it is a case creation. A team of lunatic duct tape devotees constructed a case for a Pentium 4 server entirely out of four rolls of duct tape -- there are no other structural materials or components! Follow the video and photo directions, and you can have a DTS of your own. The motto is simple: "Where there's a roll, there's a way!"
