[Patrick Becker] had an ancient PC on his hands with a blown PSU. He converted this into a stylish home for his Betta splendens.

The aquarium itself is fashioned from a piece for construction glass block with the top cut off. This allows for a window that looks through the tank and shows off the motherboard on the other side. He patched into the AC connector so that the original power cord can be used to control the pump. A lighted pump button was added to the front panel and a fancy bezel fitted to the viewing portal in the side of the case. He finished off the project with a PVC pipe for air and food. His blue screen of death now features water and a real fish.
