Yes, I would recommend EVGA GeForce GTX 1060 6GB's and it would work well with your i5's and SSD's so you can save some money and also I am so impressed on your plan that you will scavenge some parts of the machine so you can have some spare for that. Good Luck on your setup!!
EVGA offers a $299.99 unit that's a full size card with 2 fans or the EVGA (SC) which is only $274.99. The clock speeds and other things are identical, but I feel that the larger card with two fans is preferred. Is that correct?
Yes, Most GPU miners today use dual fans for excellent cooling while benchmarking as it gives the cards to work more efficient than single fans for mining, also triple-fanned graphic cards are overkill and bulky so dual-fanned cards are exceptional and efficient at the most.
