There's a world of difference between cooling 2 or 3 GPUs and cooling 6.
What the hell do you not understand about this?
I understand it perfectly well, as you can see. My uneducated ass designed and built that case from scratch, and it keeps 6 in the 70s or less. Can't quite understand why you are so concerned about it? Op only asked about 2.Did he ever say re-purpose exclusively for mining or indicate that he only intends to mine on the machine? NO.
'I would buy a name brand 80 gold 750W supply instead though, and parallel another 650W supply for two more cards when you get them.'
Yeah, that's not a terrible idea but I would be interested in knowing how you reached the conclusion that the relative additional cost of a gold efficiency PSU is offset in by power savings, especially when the difference between silver (or even bronze!) can be minimal at best, depending on the relative efficiency ratings and operating conditions. Of course, there may be situations where there is no additional cost for a gold efficiency PSU. However, such situations are not a constant, nor would they even be a norm.
You seem to like drawing interesting conclusions supported mostly by opinion and you're unwilling to acknowledge your tendency, otherwise you would have engaged in this conversation like something other than a little immature kid.

I'm done after my last little edit. I simply said I COULD build a 6 gpu rig capable machine FOR LESS. LOGIC would indicate that a rig capable of running less cards, like two, WOULD BE CHEAPER STILL. OP found that out.
This random bit about 80 gold power supplies is hilarious. Really grasping for anything aint' ya?
New rig planned there only runs three cards there, dingus. Unless you want to grasp at the converter card straw you already missed?
