I'd pay a little less for RGB ram, a little less for a mobo, maybe swap to a 2700X for a quieter CPU cooler with more cores, pick a bit pricier case.
But that GPU seems so misplaced here. You can easily put in a 2060 Super or a RX 5700 XT into a $900 budget build. I'd recommend something like a 500GB NVMe and upgrade with larger storage later, than buying a last gen GPU
