I almost got insanely jealous, as that is a nice 70GH/s setup! Then I realized that picture represents almost $400,000 worth of hardware, and I changed my mind. 
$400K? What went up 10x overnight ... BTC or the price of blades?Seriously though these blades are good in the sense that people can continue to build jerry-rigged setups using ASICs. Can wait to see these put into milk crates.
