After talking with some of the very helpful people on the forum, I have mainly gone against everything they have said (

) and come up with this idea:
A portable cab that is basically a monitor (Small, 13-15") in a box, but angled upwards. You basically place whatever computer tower you want on the back, where a kind of tray is, and then you plug it in to the extending wires... The front is customizable to have whatever control panel you want, as you just place it on and fix it on some how, and put the wire through the hole. I am personally going to use one gamecube arcade stick connected through a usb adapter to the computer, and have a space for an extra one...
I guess it's basically a bartop, and I like it because of the versatility and small size...
Check out the diagram below...
