Yeah, I'm heading down that road slowly. I only started kegging this spring and have only the two kegs right now so its not an issue yet. The plan is definitely to move the CO2 outside and add 2 more kegs but I'm waiting until I get my 4-way secondary regulator and a 3rd keg. I'm actually I bit worried about getting the 4th keg in there, side by side they're going to be a real tight squeeze, tried it quick when I put it it all back together and they acted like they weren't going to fit. I think they will with a bit more force applied but since I don't need them to fit that way yet I held off.
As for the freezer, that holds all the Costco stuff and there's no way SHMBO is letting me take that. Plus its much smaller, probably only room for 2 unless I stacked vertically.
