It needs to have cooling. Fans fliters.
Moderate climate is good.
Safe from theft.
Good internet.
5 cent power or less.is really good.
220-240 volt power.
My 2 cents ... With such conditions, only Ukraine comes to my mind ... with the only difference in electricity costs 6 cents / kilowatt. In the rest, everything is as you indicated ... quite a civilized country, stable Internet, electricity supply and a very favorable climate. And if the owner of the mining equipment is ready to move to a new country, then he will be very surprised at the affordable prices for food and housing for a comfortable life.

So I need to fire up a pc so that loading an image is easy to do.
