whatever design i go with, i plan on using it for more than just MAME (you can see my xbox 360 in the picture). the showcase cabinets worry me, because the sucker is just ridiculously heavy and i can see it easily tipping over. i live in Alaska so earthquakes are quite common here. the low center of gravity cabinets like X-Men and Gauntlet are probably better, unless someone knows of a plan for a very stable showcase design.
