Most ICs are rated to operate down to 0°C, which is 32°F.  Below that, 
it's a toss-up.  Many years ago I designed a circuit with an op-amp that
was rated (I discovered after the fact) at 0°C.  At -15°C it stopped 
working!  I had to replace it with a device with inferior specs, but 
that was rated to -40°C.

What may save your bacon is the fact that the computer generates 
internal heat, and may get warm enough to keep everything happy, 
particularly if the fan(s) have thermostatic control.
