Empty as in not even a power supply? No control panel?
You will almost certainly spend more acquiring the parts than the game is worth. If you are okay with that (I for example wanted a fully restored one) then no big deal... I paid less than $200 for mine with power supply, new base and new t-molding included. Marquee light was there as was coin door and mechs too.
If you are just getting stripped empty cab... $0 to $50 may be high to be honest.
