need help with computer part compatibility

Motherboard is too expensive for the i3 to be paired with it.

RAM is better off as 2 x 8GB, not 1 x 16GB.

No need for 3rd part CPU cooler, as the stock one is good enough for the 8100.

PSU has to be better. Go for 600W for future upgradability.

For $1900, this would be much better:

If you do not mind an unactivated Windows, and plan to stay at 1080p, the 1060 6GB will be better than the 1060 3Gb and you do not need to buy a Windows Copy:
