Geek Alert! The PC Aquarium
The AquariumPC is a fully operational computer system designed inside a liquid-filled 5 gallon aquarium for the ultimate in silent, cool computing. Yes; The Intel/AMD CPU, motherboard, Nvidia/ATI videocard, memory, and power supply are completely submerged! And yes, you can turn on this computer to surf the internet, crunch your tax numbers, or play a game of minesweeper .
Hofer pulls of the seemingly impossible feat by filling the AquariumPC's "aquarium enclosure" with pharmaceutical grade mineral oil, chosen for the following properties:
- High heat conductivity
- No electrical conductivity
- Odorless and colorless
- Low viscosity
These characteristics allow the electronics to function normally without fear of short-circuiting, all while the mineral oil provides cooling that Hofer claims is "much more reliable than fan or liquid cooling systems." An air pump provides convective circulation of the solution in order to transfer heat out of the aquarium. The only part that is not submerged is the hard drive, whose moving parts would not properly function because the density of the oil interferes with its mechanical parts. However, we don't see why you couldn't use a solid state hard drive in the AquariumPC.
The bottom of the AquariumPC is even lined with gravel for the full aquarium effect. No; You can't keep fish in the mineral oil.
Prices range from $500-600 for a fully assembled computer ... not bad considering you'll be the only guy on your block with a PC aquarium; It's a guaranteed conversation piece. Here is a video of the AquariumPC in action.
