I'd love to see whatever they're coming out with be a direct drop in / swap for the current systems. As in unscrew the old boards, swap the heatsinks to the new boards, and screw in the new ones.
would be nice, though i expect the housing doesnt cost much to produce, maybe just some shipping expense.
anyway to get a better power consumption from these? 1.2w/GH is becoming too much power usage for where i live, and I'd be happy to lose 25% of my hashrate in exchange for <1w/gh
