The PC itself is a beast: An Intel Core i7-3770K clocked at 4.5GHz, with twin Radeon HD 7970 graphics cards. Like Schropp’s Lego workstation, the wind tunnel-cooled computer is used for grid computing — in specific, IBM’s World Community Grid, which researches possible cures for cancer and AIDS. But enough about the specs: What we really care about is that Schropp built a damn wind tunnel to cool his PC. Building the wind tunnel seems like it was fairly easy: Schropp built the basic shape out of MDF edged with aluminium, with a couple of pieces of polycarbonate forming the see-through window around the PC itself. Schropp then painted the whole thing, added some awesome buttons to the front of the case, put a standard box fan at the entrance to the tunnel (recessed a little, to reduce its noise output), and finally mounted his PC in the middle. The end result is a fantastic-looking case — and, almost as an added bonus, it’s also quite effective as a cooling solution."
