There is no reason to get into a forum battle... as who wins? No one. Honestly forum battling just is not worth it. I will say what I did not agree with and leave it with that. OP mentioned "I want to build an outside bitcoin mining box that will have a roof and vents for Antminer s7". So I take this as a box not a super designed "heated shed" type device. You anwsered him with:
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.
So were talking about reading thread though re-reading this is 3rd comment so hard to get it mixed up. I still say putting a miner outside is not a good idea in a box as I don't see most having the build quality for outside air (rain/snow/heat/dust/etc). But I do stick with in no way does a rig currently mining mean it's ok.
You can go back and forth if you want. Mix and twist posts but I don't agree with your original idea and that is my opinion. But I will leave it here as I was not seeking a forum battle.
