Can someone please give their opinion about my pcpartpicker list? - Feddit

I really only once built my own pc and that was years ago. Now i finally have a nice job and have around a budget of 2k € to buy a pc. Im from europe, so no american prices for me. https://de.pcpartpicker.com/list/Y7YFBj [https://de.pcpartpicker.com/list/Y7YFBj] A friend of mine said maybe another CPU would be better? The reason i chose a watercooler was to get it very quiet. Does that achieve that? Do they have other issues i should be aware of? I only will use this pc for gaming and watching movies. Nothing much more. I dont want a curved screen, but i dont even know if i need 165 Hz. I play shooters but only casually. Thanks for the input already :)
