Here's a case I've knocked up after someone on the forum mentioned a tardis case. It's made from a dalek bubble bath container. I've cut out in inside bottle to make room for the pi. The pi is mounted on a piece of wood shaped to fit into the dalek base and I've slotted the top to let the wires out. Best thing about the dalek case is the more wires sticking out the more Dr Who it looks.
