I was being conservative by saying 8 feet. It's actually about 4 - 5 feet max. I just wanted to make sure it would be OK and that the signal would not suffer. My arcade is going into my computer room/office/arcade

So the arcade unit would be sitting right next to my computer desk. I would probably get an extension for the control panel, and sound card too. No biggie. I was mainly concerned with the video portion.
