Just heard back from SFards. Doesn't look like they are doing any demo or evaluation units at this time, unfortunately. They are doing MOQ 100 for the initial sales run due to limited quantity, and have not yet established shipping date or price.
Maybe this has already been addressed... I have yet to get as far as your post at the moment, Xian01.
I expect these rigs to be no less than $500.00 USD each [including shipping]. That would be $50,000 minimum someone would have to invest on rigs they are not certain will achieve what is advertised. Then they would have to possibly purchase PSU's and PCI-e cords if they do not have them already. I would be pissed off if I'm told a wattage at a certain hash rate, only to find out the hash rate and power per watts was off by 20% to the negative for us (not as efficient and not as fast as advertised).
I want to believe in SFards and have confidence in them. The best way to begin "trust" is with demo units to hero or legendary members in my opinion. I have no experience with their warranty and customer support. The list goes on...
They are asking buyers to have a lot of faith in them. Especially, buyers who have no experience with them. I'm not saying these things to be negative about SFards by no means!!!!!! I'm simply trying to help SFards understand our point of view.
