Gigabyte Fish Tank
Immersion-cooled desktops are head-turning in their own right. They typically use mineral oil or a synthetic non-conductive liquid to surround the components and cool them. Here, Gigabyte took the design a step further, adding water with live fish on top of the coolant layer, and artfully arranging the graphics card to serve as a kind of artificial reef. Note: Nothing's separating the water and coolant, just the fact that the liquids don't mix.
