A Practical Approach To Shushing Your PC

An anonymous reader points to this wacky but effective-looking home-brewed answer to computer noise, consisting of a wooden case stuffed with ventilation shafts which follow a number of 180-degree turns, and implementing several ideas found at 12ghosts.de (in German). From the description on the site: "By traveling through the shafts, the noise is weakened gradually on its way through the sections. On the front the case has a door for accessing drives, the cables come out of a kind of "mouse hole" at the rear panel. A fan inside pulls an air flow through the wooden box."
