These are all rev 3 units, all hash at 832 MH/s or higher.
Will ship 3 day continental US.
10 BTC per single, if someone takes all 20 I will apply a discount.
Thanks!
It sounds very interesting, but I do not think that such a hash rate is worth 10 BTC. Perhaps it is worth 1 BTC, but even that is not clear, with the ASICs raising difficulty.
