I see no other suitable case for a Raspberry Pi mini computer than a Raspberry Pie. This is my original custom "Baked" Raspberry Pi case mod.
A case to house your Raspberry Pi model B in shape of a pie, preventing damage to the chip board and making it easier to transport. The case snaps together to keep the board nice and secure inside, with gaps for the two USB ports and the 10/100 Ethernet controller. The Raspberry Pi is a credit-card-sized single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools.
