Mac Media Center (Unofficial) Edition
This is certainly nowhere near to the handsome "media centers" we have seen and might even give some Apple designers nightmares, just because Media Mac as it's called by John Calhoun (the brain behind this contraption) is powered by an old 12-inch Powerbook and some other salvaged but beautiful Apple hardware and yet looks like Frankenstein.
To John's credit however, it does supposedly play MP3s, DVDs, TV and does iChat too. And regardless of the look, we do think it's a nice idea. But, maybe next time he could just get a Mac Mini!
