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.

Aquarium Module V2

The aquarium module contains all the parts necessary to mount your computer hardware in the aquarium. It would be the equivalent of the computer chassis. This system is capable of dissipating the heat without a radiator with only very low end systems.


This item is no longer in production. Please see our V4 kit!

Includes: 

Modded 6 gal. aquarium tank

The aquarium needs some brackets removed and trimmed before it can fit a motherboard tray.

Custom motherboard tray V2

We have designed an acrylic motherboard tray for this exact purpose. Each one is waterjet cut, and includes an aluminum IO panel, motherboard standoffs, and all necessary screws.

Power/HDD LEDs

Since the oil is clear, you can attach LEDs directly onto the motherboard headers!

Power switch

Mounts to the top of the acrylic motherboard panel.

Power socket

Mounted to the top panel, this power socket is important in preventing wicking. Includes a modded extension cord to bottom of tank.

Right angle power cord

To connect underneath the plastic hood, the aquarium computer requires a right-angle power cord.




Includes all mod work needed (cutting, soldering, drilling, etc), and assembly. This work is quite extensive, and is not done if you purchase each component separately from our parts store.


Does NOT Include (but you might want): 

Cold Cathode 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.

Submerged Mounting bracket

Allows items such as SSD hard drives, water pumps, and just about anything else to be mounted submerged in the oil. Includes all necessary screws.

SATA/Power Pass Through

To run non-SSD hard drives outside the oil, this adapter is necessary if you do not have eSATA on your motherboard. It also provides molex power to the fans on the radiator.
