Thanks guys
Actually that hole was cut for a 17" widescreen. The holes cut for the monitor edges are look wavy like bacon. I kinda eye balled the width to accommodate two adult players. This design might be better suited for a single player set up.
I didn't like the way the widescreen looked, so I bought a 19inch LCD 5:4 monitor. By the time I am done with this, the monitor bezel will be lower, and probably won't be made out of plywood. Or at least it will be covered by plexi.
I finally filled the extra holes on the cp. I'll end up painting that black for now, may cover it with artwork sometime later.
