Mineral Oil Submerged Computer

I am a sucker for interesting mods. http://www.pugetsystems.com/submerged.php

We built this system because with all the oil cooled projects out there, no one built a system that looked good and functioned well! After seeing all the other projects, we had a lot of ideas of how we could do it better and more easily. Many projects used vegetable oil, which would go rancid after a short time. The mineral oil does not have this problem, and is completely clear. We also wanted to use an appropriate enclosure — the Toms Hardware system used a clear acrylic case, and they had to painstakingly seal each rear connector to keep the oil from leaking.
