We don't heat our whole house...just the living room and kitchen when it's really cold and a little electric heater in the room with the incoming water pipes and washer.
I have a spare computer in the back room that will get below freezing when the temperature drops into the teens towards the end of the week...maybe as low as 5 degrees F one of those mornings so I expect that room to be well below freezing.
I don't plan to move it or even use it during that time...just wondering if cold will hurt anything?
It's shut down and unplugged.

I had a laptop that got into the 20s many times in my service truck. It would make me wait while it warmed up in the mornings but worked many many years.
I think freezing with moisture would be a problem. Moisture without freezing would be a problem.
