Let me know, I am making my cab a dual xbox 360/mame cab. Have a KVM that switches the sound and video, externally mounted the dvd so the xbox is completely hidden Considering all the great arcade style games coming out, fighters, nba jam, lego star wars... its like having an old school cab and a new school one.
At the rate of my progress, I figure I will be finished right around the time a book three will come out, and it will be timely too, because they will probably be on the xb0x-1080 and 360's will be like 10 bucks on ebay...
