The main LCD is 42", 27" LCD for the backglass. I'll be adding a 19" monitor for the dot matrix display (DMD) screen (the one with the score). I went cheap for the sound, a Logitec 50W sub/speaker setup for $99. There are a lot of examples out there of people who made one of these, and they play great. Search YouTube for "Visual Pinball" and you'll see ton's of examples.
