Get rid of that USB wifi adapter and get a built in wifi card in the mobo. USB adapters are horribly unreliable and break often. You could get a pcie wifi card instead too.
I’d go down to a 5800x3d to save money on ram, mobo and the 7900x is a little overkill when you’re getting a 6750xt, you could stay in the 7000 series and go with the 7800x3d if you so desire. You could also upgrade to the 6800/6850xt or 7700 for a bit better gaming performance
I would also put more money into the keyboard, it doesn’t look mechanical though it is up to your personal preference entirely. I personally would go mechanical.
