Can someone help me build a gaming pc for around 1200$

So I think I managed to squeeze the most out of a 1200 with tax budget.  I included a copy of windows and still managed a nvme boot drive with a good seagate mass storage drive.  If you don't need/want the copy of windows then I would suggest putting that 140 bucks into getting some better storage and perhaps go with a better x570 mobo instead of the B450 tomahawk board.  Nothing wrong with the B450 board its a staple of mid grade amd builds.  Now technically assuming a 15% sales tax the cost of all this comes to 1216 and change but I figured 20 bucks can be managed somewhere to cover that little extra cost.  Enjoy

There's lots of room for future updates with this set up, like a CPU, M.2, and more ram. But the bones are really good. The 2070 super is way better than the 2060 and the EVGA power supply will last for many years.
