old threads never die...they just fade away...oops....I meant they fade back???
it depends ENTIRLY on your personal situation.
Inside just looks cleaner. But outside means more keg room inside.
My 1946 Westinghouse fridge is featured in the living room. 3 kegs and a 20# inside makes for a very nice display. A tank outside is just not an option.
My kezzer is under the sloped space under the stairs. It fits 4 on the floor and I have CO2 and nitro tanks outside, but hidden in the under stairs storage crawl space.
Have to agree with @OakIslandBrewery. I'd like to see that old Westinghouse myself. Vintage kegerator/keezers are to homebrew like hot rods/muscle cars are to gearheads.
