I want to build an outside bitcoin mining box that will have a roof and vents for Antminer s7, but will condensation be a problem? what about in the winter will it be too cold for it? I live in Canada. In the summer would it be too hot? Rain won't be the issue I will come up with a pretty good box design. What if it shuts down for what ever reason will it be okay?
As long as the rigs are mining, i think its okay. But if snow get in there, not so much. If you shut it down, i dont think you should boot it at -40C, no. Typically the best is to dump the heat out. If it was a proper heated shed, then sure why not, you could use the miner's output to keep the shed at a ok tempt and just vent what you need to keep the temps to something like 10C.
