$10 more for a slightly faster CPU with superior cooler. Ditch H212.
Go for ram that is a little cheaper and this ram has the benefit of being specifically designed for AMD.
The Samsung 860 500gb is a tiny bit cheaper than the MX500 500gb and the 2 drives are equivilant.
The Sapphire Pulse RX5700 will outperform the 1660 super by a fair margin. If you want to cut cost, you can go back to the 1660 super.
I added a better PSU that is only $5 more but 80+ gold and better quality.
I went with a name brand wifi adapter.
