That's what I thought. But I have seen a pic of someone mounting their bottle on it's side in a little kegerator. Seems like they had the regulator on top.
I have a dual regulator setup. I can run one line through the drain hole in the fridge without issue, but if I run two lines, I will have to enlarge the hole, or figure out some other way to run it.
I need a keezer. I can't even put six kegs and a CO2 bottle in my kegerator!
