What if I built a small (3x3x5) well insulated box. Would an AC get it cold enough? How many BTUs needed?

You can't get it to freezing with a window a/c, but you can get it to 34 degrees (not sure that would be good enough for your use) with one of these controlling a window a/c.
I have two of them (generations 4 and 5 models), on two separate window a/c units, that I use to bring two different rooms down to very low temperatures (just the way I like it); have owned them for many years, and they have been trouble free and a real life-changer for me. They are expensive, though.
If you go to the company's website, it is packed with info about building coolers, sizing a/c units, quality unit recommendations, how to install and operate the device, etc.
