I want to use something a lot less flexable to cover my monitor. I am thinking about tempered glass. I haven't worked too much with it or have any experience with it...

1. What thickness would you recommend for the front glass?

2. Is it easy/possible to cut 1 1/8" round holes it? I am considering putting some buttons up front.

3. Is it easy/possible to cut rectangle holes in it? I am considering a rolldown coin mech.

4. How would you hold the front glass in?
As you may have guessed, I am going for extremely compact countertop size.
