Computer Submerged in Mineral Oil
I have so many lube and virus jokes, but none really would be appropriate for this. At any rate, it's a cool idea.

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. We wanted to put the ports on top to solve that problem the simple way. Other people have built systems in aquariums before, but they were always oversized and square. When we found the Eclipse System 6 Aquarium, we were excited to see an aquarium that was absolutely perfect in size -- you couldn't go any smaller. In addition, we had questions about performance and long term effects. Our initial tests, which we go over below, answer the questions about cooling performance. We'll post a follow up to this page in a few months to let you know how a system like this performs in the long term.
