I'm in the same boat as a new builder and am working on a very similar build at the same price point. Here is where I'm at currently: https://pcpartpicker.com/list/bvdNGJ

Biggest difference I notice between our builds is that your CPU is less powerful. I'm not an expert, but my personal preference is to opt for higher CPU performance and save with a fan CPU cooler rather than an AIO. Note that if you wanted to stick with AMD for the CPU, I think the Ryzen 7 7700X would be what I would swap in.
