Seems like this is difficult for people to understand.
It's not a bartop. It's not a cabaret. It's a sit-down cabinet, akin to the Japanese "candy" cabinets, the white gel-coated fiberglass ones that requires you to be sitting on a chair to comfortably play.
I have seen those in person, you would need to be about 8' tall to play one of those on a bar.
The Playchoice bartop was a complete and total failure, that is why there are so few of them. No one wanted to pay money to play with dinky baby joysticks on a teeny screen.
I have also seen bartop Golden Tees and bartop Arkanoids. Also failures.
While most of the "bartops" people are building today either seem to to fall into one of two categories.
#1. Full sized cabinet with the bottom half missing.
#2. A netbook with a gamepad would have been better.
