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 and Cooling Modules 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. The cooling module pumps the mineral oil through an external radiator, which provides excellent cooling. We have verified adequate cooling with the most extreme hardware on the market at the time we built our test system (Intel QX9770 CPU, 8GB DDR3-1600 RAM, NVIDIA GTX280 video card).

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


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.

Quick disconnects

Mounts in a PCI bay, and allows the radiator to be easily removed for maintenance or transportation, and allows an oil filter to be installed in-line if desired.

Magicool Xtreme Quad 480 Radiator

Attached with quick disconnect tubing to the aquarium, this radiator can easily cool the most extreme setups we have used.

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.

Submerged Pump w/ 10mm barbs

To drive the oil through the radiator, a pump is submerged in the oil, for quiet operation.

Includes all tubing, adapters, mod work (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.

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 radiator can accommodate four 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.
