I'm talking about GPU mining for litecoin to be specific. This is a garage that is not watertight so has a degree of humid air.  From my brief readings on this subject temperature will not really be an issue as the computer will more or less heat itself. As long as it is on permanently condensation will not be a serious concern.  That leaves humidity which will rust the metal components over time and the biggest problem, dust. Anything I'm missing here? Anyone running pcs or laptops without issue in their garage?
