Grounding a metal cabinet

I have a metal cabinet (Taito Egret 29") that is connected to power using a 3 wire cable with the ground pin (and wire) removed. When I turn the cabinet on and plug the video cable into the computer I see a rather large spark. After that I seem to be able to unconnect and reconnect the video without seeing the spark. I wasn't too concerned until last night when I had one hand on the computer case and touched the arcade before connecting the video cable. Woah.
Is it safe to change the power cord to a heavy duty 3 wire cable and attach the ground wire directly to the metal case?
