Hey, very useful answer, but im currently in part of Asia where electricity is super cheap.
Current hardware i have in stock, so i'm removing dust and giving it better purpose.
Rig/Case is more for home users, where they can have their own setups for really cheap money and make few hundreds a month if they make enough of them.
Im still busy with cgminer :) It's killing me to find nice pool or decide where to start testing :)
