Most of the wiring stuffed away in the cable boxes. My old (10+ years) Dell Optiplex 360 Computer with an old Nvidia GT 240 GFX card. This old thing now runs the arcade show. It is by no means a fast PC but it does the job. I can always replace it with a new mini computer if I should need more speed or the old one gets too warm inside the cabinet. I have connected some external USB ports to be able to control the machine with a keyboard outside the arcade cabinet.
