I built two rigs at end of May, sold one about a week ago for 1k more than I paid for the parts to build it.  And I got to mine with it for 5 weeks.  I am about $350 from breakeven on the whole mining investment.  Very happy I sold the one rig!  Difficulty is crazy.  However, I would like to see the price of ETH drop more in the short term.  Weed out the weak hands and give me the opportunity to buy more!
