All hardware is new, not second hand.
Do you have the ability to produce any benchmarks for these cards so that we can know what kind of hashrate they have been receiving?
When you claim that this hardware is new and not second hand, do you mean that the cards have never been used or do you mean that you are the original owner? I'm somewhat interested in the cards, but you did not mention what price range you are interested in receiving. I have no idea what kind of hashrate, or algorithms these cards will be working with. You have provided no pictures and made no mention of escrow. There are a lot of red flags in this post and there are even more things that need to be clarified before this is to be taken seriously.
