Nostalgia Electric Kegerator - Where to drill hole for CO2?

[pvpeacock]

I have a Nostalgia Electric KRS2100 kegerator. I swapped out the single tower for a dual tap tower and installed Perlick faucets. I have been using the 2.5 lb. CO2 tank which came with the kegerator and sits inside. However, I now have access to 20 lb CO2 tanks at work which won't fit inside the kegerator. I have not been able to find a schematics on where to drill a hole for the CO2 lines or how to determine where NOT to drill. Any information or tips on drilling a hole in my kegerator would be appreciated.
