I will link this thread in my new post. I am just unwilling to sell it as individual parts anymore.
I can put a purchaser in contact with the old buyer as to my credibility.

The old buyer had them installed at a corporate office's server room.
I cannot release names to everyone without their consent I hope you understand.

Also those prices were for all the cards in bulk, i can arrange bulk discounts still.

I think you may have missed that those prices are my cost, 75btc is around 1000,

1:1.5 to 1:1.8 dollar to hash ratio, depending on the clocks.
