I built my mame cab a couple years ago. I went a little differently than most with a 55" 4k TV in portrait mode. My goal was to have a "virtual cab" so that the art work changes per game. I also did lighted buttons, but I filled in the center with black resin so that you aren't blinded by the light. It creates a nice effect that helps plays figure out which controls to use without burning your retinas out..
