It depends a LOT on what animals you want to keep.
A few years ago there was a Nano tank grow out contest. I picked warm water species and maintained the 10 gallon tank at 86F. It really thrived and I won the contest.
Someone above just stated they keep their tank at 74F so that sounds like a reasonable minimum. Again, it does depends on what you are keeping though.
