We’ve covered a lot of the oil cooled PCs, and here’s another- cooled with Sunflower oil. What we did was take some unused hardware, lying around, built an acrylic case put the hardware in and filled it with sunflower oil… lots of oil ;) Then powered the machine up and it actually didn’t fry (did someone say french fries?), instead it worked perfectly fine and in some terms a lot better then when it was air cooled.
