yeah, it isnt super flexible..but for connecting to a PC for a mame cabinet, it doesnt get much better than this. my friend's cabinet (more of a control panel and stand for the monitor at the moment) looks awesome. you need some distance between you and the monitor since it is so large..but it would be great for a showcase style mame cabinet. if you are one of those purists who have to run every game in its native resolution, then this may not work for your..but we have played hundreds of games on this thing, with mame set to output everything at 800x600, and it looks absolutely fantastic. it looks way better than a TV.
when he first got it, we hooked up a dreamcast with a VGA adapter, and it looked awesome. worked will with the lightgun games as well. i just wish i had the room for a cabinet that big
