Re: Any thoughts on when to change a miner? Did some calculation for 0.02cents/kwh.
If your not living at one of the poles 
you'll get a lot of heat from the miners in the summer and you want to dissipate this.
So you have to include some cooling or ventilation method in your calculation, otherwise your miners will have a lot of downtime.

Come to think of it, the people living at the poles (antartica) seems to be unaware of bitcoins.
Antartica is a good place to site a mining farm, you spend less on ventilation
