What I mean by that, is do you use a PC inside the table/display that is within the display box/table, a self contained unit. Or is it that you just connect the cables and use an external PC.

I am planning* to either shove a PC into the display box or the guts of one at least and have the unit self contained. If I can get the money to spare that is, otherwise is a Connection board setup so I can just plug in main pc or a laptop.

*You know what happens to plans when they meet reality.
