External CO2 Tank with Beverage-Air BM23 Kegerator

Does anyone know if there is a safe place to pass a CO2 line through a BM23 kegerator? I'm considering moving up to a 20lb CO2 tank instead of the 5lb in the kegerator.

 

There should be a drain hole somewhere in the back of the fridge that works for passing lines/hoses through

 

I have the same refrigerator. I think there might be a way to put a tube in through the back. If you take the skinny vertical panel off on the right side, where some electricals run you might be able to slip in a co2 line there. It comes off with a few screws but has refrig. lines (if i remember right) also so be careful. If you figure this out, let me know I am interested.

 

Did anybody ever try this? I have the same question...

 

i have one, and when i got it the hose was already going out the back wall, on the lower right-ish side.

 

Lower right side seems to be the place but with as much as these things go for new I wouldn't go punching holes in one.
