eBay, Craigslist, etc.
For the case search "pvm porta brace case" or "pvm field case"
You will need BNC RGBHV cable which likely has a VGA connector on one end.
To use with a JAMMA connector/ arcade board you can either hack the cable or use a VGA breakout.
The 5" also needs a BNC T-adapter to combine the H and V sync.
