Sealing The Plexiglas Case

Strip Out The Fans, Add 8 Gallons of Cooking Oil

We struck gold by finding a transparent case to show off our DIY oil PC masterwork.

The underlying thought behind this project was to design a system that cooled the components by total submersion in a liquid-filled case. The lab engineers immediately set two conditions: The system should run silently and only choice hardware should be used. We also sought out an attractive container or case. Using an aquarium was excluded from the very beginning - cables and connections couldn't be cleanly brought from the inside to the outside. The system had to look good, too. In the end, we decided on a transparent PC case made of Plexiglas, which however meant an immense labor expense. All contact surfaces of the individual edges had to be glued and made airtight. The sealing of boreholes and openings on the individual slabs meant additional effort. Step by step, first special glue and then silicone were used. The latter particularly needs time to cure, making the use of a dryer recommended.

All screw joints in the case have to be loosened, followed by wetting with special glue.

To seal the openings, we got Plexiglas slabs that we cut accordingly. If you expect the oil smell to be a problem, then you should plan for a top cover right away. However, the heat exchange between the oil liquid and the environment will then be altered.

All parts of the case must have airtight contacts.
