Just wanted to share with you guys, since I put in the last GPU in today.  Have been mining since 2013 but mostly ASIC's, some GPU's.  Sold off most of the stuff in 2015, then early 2016 decided to get back in (my garage was cold).  Started with 2x380s and 2x390s (sold the 5870s lol).  Eventually sold the 380s+390s+280x in the height of the summer folly. With profits and bitcoin price rise, bought everything else gradually.  So all you see is paid off (plus some more), + all work and accessories (240v+pdu's), electrician work, fans, etc.  Power costs are about 5-6c usd.  Most are 470s/570s, some 480/580s, 1070s, maybe 10 1080tis and 2 1080s, total : 59 GPUs in the house (56 in the garage).

Started from this:



to this:




In approx 14 months.  I'm pretty happy, since I never had any real money to invest.  Electric is 100A only...so yeah im maxed out pretty much, total is about 45amps.
