A couple of S9s would have fit on that 10 guage cable, with free power you could have roied the mining gears as well as pay rent or some of it, unfortunately it is unlikely that you are ever going to have such a free power source anymore.

Myself on the other hand still have access to good amount of free power, i make sure I fully utilize it before a new government comes in and decide to charge a lot for power, i don't see that happening anytime soon but I am always prepared for such a thing to happen , and that is one of the reasons why I always buy gears that have a maximum of 6 months Roi in the worst case, tho the average is 3-5 months and thankfully I have already roied more than 80% of all gears I ever bought, except for some unfortunate D3 that I had to throw away at about 70% roi.
