ROG -STRIX-RX570-4G-GAMING  13 x $280.39 = $3,651
Hash Rate NeoScrypt is about 8,000 kH/s
TDP 150W (90% is 135W)

Asus GTX 1070  8 x $433 = $3,464
Hash Rate NeoScrypt is about 8,000 kH/s
TDP 150W (90% is 135W)

5 LESS cards will result in the same hashing power for $190 LESS!

You will also save 675 watts and have more room to add on later!

That 1800W power supply is NOT rated for 120V US power.....  It might work, might not!  You need about 1300 watts at 100% or 1180 watts at 90% card power.  
Two of these will suffice for $120/ea - https://www.newegg.com/Product/Product.aspx?Item=N82E16817151188
