I have not ordered a Neptune myself because I feel they need to reduce the power consumption more.
Neptunes won't run in most American households unless you're running it off two circuits. As tempting as it was to purchase one, the harsh reality of "this just won't run in my home" made it a no-buy
IMHO It won't be long before a miner costs 20k, and is dedicated 220v
like the 14nm 3-D FinFen tec... hope KNC/AllChip has started that!
