/diy/ - Do It Yourself

TLDR are college size fridges of any use for small scale homebrew?
I've been using Mr Beer 2 gallon keg to make up batches of beer in S FL. One of the issues I have is ferment temp. The coolest place in the house is the kitchen / inside, and it's around 78F at lowest during most of the year, which is a little high for what most recipes call for.
I've got a college size fridge that either needs put to use or donated, and wondering if that would be useful to drop the ferment temp down... whether it's worth the hassle. I've got PID controller and can force the fridge to maintain whatever temp I want. I'm mostly making IPAs, stouts, and wheat beers, and maybe it's not really needed unless I start making lagers / pils.
