Glad you cleared it up!
I hope you can see how it would look, since you're giving us your questions about this in piecemeal fashion. Asking about the monitor and "etc" isn't really going to help us help you.
The more information given in a post when asking questions, the better, as NOT giving information leaves you open for all kinds of replies, as you've seen.
When left to our own devices in guessing what people are looking for, much can be misinterpreted.
How about this for help: I bet they use MDF, and of the examples I've seen of that jukebox, one chose to paint it, one chose to laminate it. Particle board would work for this application, but plywood would probably be your best choice, and you could probably get away with 1/2" stuff too, for lighter weight.
When mounting it, I'd make sure to use a stud finder, and make sure it is securely mounted to a wall stud.
What else can we help with to make your jukebox?
