1 a Wii inside an xbox 360 ( the original white one)
since the wii is smaller than a xbox internals use the extra space for a pop out charging station for 2 controlers
also keep in mind a neat place for if someone has soft modded there wii, a place for a portable HDD
2 a wii in a puzzel box
same concept
3 a wii in a snes
like the ones on youtube but more hidden
same concept
