Theres so many factors and how much you can do yourself also helps. I bought a game for the cabinet, mechs, switches and wiring harness to use with a proc. You will end up buying tools along the way. I bought a tig welder and a 3d printer in the process. Its alot of fun and will take ALOT of time. How crazy you go will determine the overall costs, but Mbecker is dead on his price estimates listed.
