i5 and a 1060 with quality parts or a i7 and 1060 with decent parts

Solution
you've not got a PSU on the i5 build.
The water cooler is probably worse than the aircooler on the other build.
The WD black is by no means an inferior drive
the 1x16GB stick is a problem.
There's no need for the expensive mobo.

Frankly too much of a pain in the rear to compare them any further.

try asking the question, from this shop what should I get for 1600.
