The Screen Savers have a story on their website about the building of a single box 2600/PS2/GameCube/Xbox/PC/ NES player. But this is not a mame ? box. The builder, Yoshi, dismantled, cut,chopped and belt-sanded the consoles to make them all fit in the same Lian-76 case. I can only imagine how hot this case might get. There is a photo album here. It looks like you'd still need a video switcher to take advantage of this completely. A cool mod for this would be to pack in a wintv card for each console or something.
