Just my opinion, but I think it mostly effects our non-computerized components, such as backs, shoulders, knees.

Computers (in general) don't mind the cold. In fact it is better for them. Rooms for servers are always cooled to prevent overheating. One of the companies I have done work for, had a group of women that "needed" keys to the server room as they had hot flashes and needed the walk-in cooler.... Computers usually have trouble in the heat. Give them enough heat and their computer boards will have to be replaced as bits will melt and they won't work as designed.
The machine parts might have issues with the cold, but I doubt most of our homes could get cold enough to bother them.

My sewing/computer room is in the basement; it never goes above 70F in the summer and I have a space heater and heated throw to use in the winter when it often drops to below 60F. General household temperatures should not be detrimental to our machines but extreme outdoor conditions could be problematic.
