How cold is too cold?

[Crowbar]

If you're using the machine each day I would be concerned. The components are being heated up each time you use it and then cooling quite a bit at night. That means the components are expanding and contracting every day, much more than they would if the computer were indoors. Pieces will wear out faster, thermal contact could be compromised, electrical contacts could be interrupted.

If it's being used frequently I would just leave it on 24/7.

Why i said to look up "chip creep" what's the metal expanding/contracting untill proper contacts are not held/made.
