1st Build in 10yrs

Gaming: COD, Rainbow 6, CSGO, D3, everything and anything new!! Sooo the current market is rough right now so I bought everything and anything whether I needed it or not then returned what I don't use or need. However, it's been 10yrs since my last build Ryzen is all new to me and when I initially walked in to purchase parts I went in with a casual head of "ladadada building a new PC what to get what to get" not knowing it's the 5600x release and everyone is buying everything sooo I went into panic mode of "what do I get uhh excuse me sir. u got any recommendations on what to go for? Or Soo what u grabbing today? Or "wow man today is crazy what build u building?" Obviously to not sound like a noob and I kind of went off that. However, now that I've built, seen everything, and we'll informed here are the things I'd do differently.
Ryzen 7 5800x
EVGA 3080
360 cappelix
5000D Airflow or lian li lo xl
QL FANS
Corsair rgb ram
Don't get me wrong I'm more than satisfied with my build 1000% speaking if I could go back in time then this is more the route I'd go.
