I moved my server into the garage from my office over the summer because of heat. It sits right next to the garage door in a new attached insulated garage. I'm in OR we've been getting in the 20's, not sure garage temp but it gets pretty cold. We'll probably see a peak low of about 15f in the winter. I'm a little worried that it may damage something. The case is a Phanteks enthoo with tempered glass so not keeping any cold out.
