My cabinet is only 5 ft. tall. It's perfect size for an adult to sit at (it is my full-time computer as well for internet, word processing, etc.), and the monitor is at the perfect height. It's also nice for the nephews who love to play it as well. I would like to build a full sized one when I get a little more room, and I'll use my 25" TV for that one. Sitting at an arcade machine (though much more comfortable) just doesn't have the same "feel" that standing at one does.
