About to start building a keezer

Kegging

I have a couple questions about a keezer I’m about to build.

  1. I have limited space for this thing and one of them is the garage. Now I am getting a 20lb. CO2 tank and I know it will not fit in the freezer. So, would it be okay to sit outside in the garage when the temp can get to below 0 here in Minnesota?
  2. I also need a CO2 regulator and I have pinlock kegs and I keep on seeing ones that say for “corny kegs” Is there a difference, and if so what do I need?
    Thanks in advance.

2 that one will be fine. You have pin-lock style corny kegs. There are also ball-lock style corny kegs. Both use the same regulator, just a different gas-in connection.
