What types of damage could the machine takes if they are placed outside in the scandinavian winter.
whit roof . no walls ?
any overclock pocibilities?
Let's say s5 machines sp20s ?
this is the idea.
The Blow will be outside and the intake will be pulled from downside.
PLacing the Miners on the balconi the intake should not bring any moisture from the downside.
Weather is pretty dry were i live.
The little box will be weather prooff so no water or snow will be getting inside.

First of all, i love your Paint skills.

The idea is good but make sure to protect your miners against any form of liquid (rain, snow, frost etc.). Cooling won't be your problem and if your energy cost are low to very low,
Why not give it a try
