Nothing is cooler than seeing a custom pc set-up, except when seeing that the pc runs while in liquid. These guys provide a how-to on creating a pc submerged in mineral oil. They chose to take on this task because the other demonstrations out there did not function as well or look as cool. Not only are custom pcs normally visually stunning but they are also relatively cheap to build once you have the know-how. Updates were also provided to follow just how this custom case performed several months afterwards.
