OP, I don't have the time to explain everything, but so long as you are confident your operation won't go down, the only thing that may have a problem with temperature delta is the PSU.  The heat generated from the miners will be more than enough to keep condensation off, though... So I'd say go for it, just have a spare Psu in case...  But I have all of my miners outsideand I've never had a problem, two of them reside on my balcony, in fact.
