Update: I've done this for over two years and haven't had any issues at all. It is fine.
I use the RPi to measure the temperature of homebrew beer. I currently just brew in my closet, but I would like to buy a chest-freezer/refridgerator which would combat the heat during the summer (temperature is arguably the most important variable to control for in brewing).
It would be much easier for me if I could place the RPi inside of the chest freezer, which I would set at 55-60*F. Can a RPi withstand this temperature without degrading more than it would otherwise?
I do realize that over the winter my apartment went much lower than 60*F; however, this wasn't a 24/7/365 constant, but only during night times.
