For me power is reasonable inexpensive and I have access to ample capacity.  I was a little surprised at how much per circuit it cost me to build it though.  Unfortunately the building I am in has 480/276V so have to transform it to 3ph 208v.

I like now that I can buy the M3 with PayPal, much easier than BTC/BCH.  Unfortunately our exchanges in Canada are not that reliable right now for sending or receiving fiat.  I did just get verified on Kraken though and it seems to be working well.
