Are you guys pricing in the cost of the air conditioning required to cool the extra amount of heat your rigs are cotributing to your living space? Is there a rule of thumb to price this into one's calculations in wattage?
What airco? Just put the machines spread out over a few rooms and use them to heat the house... That's how I do it here... Not so much fun in July (as it was extremely hot here) but August was a pretty cool month and in September we'll have no need to swich on the heating system
Where I live, it's still hot enough outside to require running the A/C, so until it gets colder outside, any additional heat produced by my rig is an additional cost, because the A/C has to run that much more.
Anyway, the question was more general than that, I'd simply like to know a way to calculate this additional cost using a rule o thumb of some sort.
