Mineral Oil Cooled PC

Project Ready DIY Kit for the PC Enthusiast

WARNING: Submerging your hardware in mineral oil will void your warranty. Do this project only at your own risk. Puget Systems is not liable for any hardware problems, or damage to your personal property. Mineral oil is very difficult, if not impossible to clean from your components once they are submerged.

Other items you may need:


Available from Puget Systems: 

Cold Cathode/LED Lights

The aquarium kit has been specifically designed to allow for the mounting of cold cathode lights to the top of the system, shining down into the oil. Mounting holes provide convenient attachment.

120mm Fans

Since there is a wide variation of 120mm fans to choose from, we do not include any with the kits, but rather allow you to order them separately to suit your tastes. The V2 radiator can accommodate four 120mm fans, and the V3/V4 radiator can accomodate nine 120mm fans.

120mm Fan Grills

Protect the fan blades, and give a nice visual touch to the radiator with chrome fan grills.

12V Molex DC Power Supply

Provide dedicated power to the radiator fans, allowing you to free up the power port on the aquarium kit to power hard drives.

Additional SATA/Power Pass Through

Allows a second hard drive to be run outside the oil (there is mounting on the V3 and V4 kit for both a 2.5 inch and a 3.5 inch hard drive).


Not Available from Puget Systems: 

Mineral Oil

Available at your local hardware store, farm supply store, or vet clinic. Mineral oil is used as a horse laxative, and as funny as it seems, that mineral oil will be medical grade, ensuring the highest purity. Expect to pay about $20 per gallon. We have also worked with STE Oil to get them to list a product specifically for this project, which you can order online.

Aquarium Rocks
Available at your local pet store, aquarium rocks come in various colors and types. These rocks can be a cheap way to really make your computer look like an aquarium! TIP: Wash your rocks before putting them in the aquarium! They are often covered in dust and other particles, which can cause your aquarium to look cloudy. Put them in a towel, and rinse them off in a sink, then spread them out and allow them time to thoroughly dry.

Bubble Bar, Tubing, Pump, and Flow Valve
Also available at your local pet stock, bubbles are an essential addon! We recommend a 6 inch bar, and recommend washing it as recommended for the rocks. The flow valve is necessary as we've found it very convenient to be able to control the flow of air. The valve also provides a convenient joint at which you can disconnect your air tubing if you need to work on or move the system.

Cleaning Supplies and Tools
Mineral oil is messy! Make sure you have the following items on hand: a funnel for cleaning filling the system, paper towels to clean up spills and clean your hands, and orange clean to help make cleanup easier.

USB / Network Storage
Since it is not feasible to keep optical drives or large amounts of storage on the aquarium system, we recommend a USB DVDRW for OS installation, and network attached storage for your files.
