Alright, I'll do my best at answering all the questions:
That's a 19" Flat Screen CRT monitor. I didn't realize that was big for a cocktail, lol.
Since it's powered by a 1ghz HP Pavilion, it doesn't generate much heat in there at all. Even so, I have a clear fan blowing air out a grill on the side. You can sort of see it on the bottom right of the 2nd picture.
Melarky: I was actually the person that replied to your thread telling you what I did. I have the horizontal and vertical player 1 controls hooked up to the same ports on my IPAC2 keyboard emulator, and the same goes for the player 2 controls. I set MaLa so when I move the player 1 controls, the screen flips and displays vertical games. When I move the player 2 controls, the screen flips and displays horizontal games. It was the easiest workaround I could think of. The only annoying part is having to explain it to guests. Aside from that, it works great.
I used tempered Graylite 14 glass, which seems perfect. I couldn't imagine having it any darker than that. The guy at the glass place rounded and smoothed the edges for me. It was SUPPOSED to be pretty expensive, but the guy misquoted me, charging me the UNtempered price for my tempered glass. So it only ended up costing me $75, but I imagine it generally costs a lot more. I wouldn't get anything other than tempered glass though, as untempered (I think they call it annealed) is really fragile.
I only have 4 buttons on each of my end control panels, and 6 on the horizontal ones. I haven't played any games yet that use more than 3 buttons, so I like what I have.
Thanks for everyone's compliments; I'd be happy to answer any more questions as well.
