Cold liquor storage

Hey all! I got really into cocktail making this year, and now I find myself with a plethora or things that require refrigeration. I don’t want a wine cooler, since the bottles are sometimes irregularly shaped. I’m talking mostly vermouths, limoncello, coffee liquors, etc…I’ve been checking out things like 2.5-4.4 cu ft mini fridges on Macbid, but have a hard time gauging what an ideal size would be. Does anyone here use anything specifically for chilled spirits that is space conscious? Thanks!
