I think the coolest thing about this page is that in German an Oilcomputer is an lrechner, which sounds very Checkpoint Charlie spy mission. "Sir! The lrechner is ready! We must attack!"
The creator of the lrechner, Markus Leonhardt, basically dunked his entire PC into a fish tank of grease. It keeps the entire thing cool and doesn't short out but I would absolutely hate to have to reach in there to plug in a USB key or whatever. Luckily, he thought of that as well and ran all the outputs through the glass and into the open. Plus, if it gets hot enough, you can fry fish!
