Air cooling, water cooling, phase-change cooling... all of them are already too familiar and even boring. So why not to think of something new to experiment with, how about a computer fully (or almost fully) immersed in a vegetable oil. Does it sound crazy to you, well it is a bit strange and you may call it even a weird idea, but it really works. See the Sunflower Oil cooled PC (stage 1) in action...
