Show me your beaver
I'm a fan of case mods, where you stuff a PC into something other than a beige box.
I've done two myself, one where I put a PC on two parallel pieces of Plexiglas, a failure because it's noisy as hell, and one where I wanted a rustic wooden box, but due to the motherboard size, ended up being a monstrosity of a bird house, a failure as well. Someday though!
Here someone uses a stuffed beaver for the case.
