Here in the Netherlands power costs €0,25 which is $0,32 per KWH...
But you if you got a company you can get a tax 'cut' so the power costs €0,20/$0,25
Still way to expensive.
Nice tutorial, I'm planning on building a rig with 38 GPU's.. now with 7 AMD R9 390s.. and they gulp up allot of power so this is helpfull :)!@maninjapan1989
