the above is pretty accurate.


 adding a single 350kh gridseed is about 170-180 usd.

10 = 3500kh  cost is 1700 - 1800 and you can add one at a time. add 135 to power them.


and yes I  added in psu for the 16 units     8 of these  is 80 bucks

16 = 5250kh cost would be 2700 - 2880  + 135 = 2850- 3015   for the more hash power as the new blade. about 5600

the blade = 2999.

so  it need to be under 16 5 chip units not more or equal.

 ie 2300 usd tops  and that is still a high price.
