Made some worthwhile adjustments.
- That WiFi card is overpriced, not sure why it was listed in OP. You don't need that kind of insanity to get good WiFi speed + reach.
- Motherboard with 4 RAM slots for easy upgrade room to 16GB later.
- Better SSD for same price.
- RX 580 8GB selling for only a fraction more than the 1060 3GB, considering they're marginally faster than a 1060 6GB depending on the game, well worth it.
- More reliable PSU.
- Subjectively better case.

Still awaiting response from OP though. What kind of budget are you even open to and what are you doing with the build? Looks like a budget Gaming build from original post, so build was modified accordingly. Hope this helps!
