I have been following from the sideline for a bit and now thought I would jump in.

I have very cheap electricity, so ROI would be a bit shorter and thought I would start with a 6 GPU rig. I watched a BBT episode (https://www.bitsbetrippin.io/pages/episode78) and checked the stock situation at the computer store and they had everything at home for the RX580 setup.

RX580 PowerColor Red Devil Golden Sample 8GB
ASUS Z270 PRIME A
Intel i3 6100
Corsair Vengeance LPX 3200 8GB DDR4
Sandisk 16gb 3.0
EVGA Supernova 1600 T2
7x Risers - v006 (amazon)

Anything to change?

When looking at whattomine it gives me an expected earning of ~$20/day. Is that doable with that setup?

Thanks a bunch!
