Tired of console gaming - Going back to PC gaming after a decade. Please advice!

I've put up a part list that I'm going to start purchasing from next week until March 2025. This will kinda be my first high end PC build but with the help of a friend who has done a lot before. Kindly advice what else would I need to fully complete this build. Or if I can have a better part instead of the one I picked. For e.g. I've also added an additional hdd storage to store a lot of my old crap in it. is it too much?

P.s. big thanks to this community that helped learn a lot over the past few months on pc building.
