New computer, music and games

Every day I notice more and more that my old computer (meanwhile over 10 years old, still with DDR3) is making more and more “straight leg”.
So I would like to get a new computer.
Unfortunately I’m a little off topic now and would like to ask you for advice, below I’m linking to my Geizhals wishlist.

What do I do with my computer?
I produce music with an Ableton DAW as a hobby, as I need more power for larger projects.
I also like to play some computer games, which admittedly have become less so.
I currently have two 27″ 1080p 60hz monitors that I would like to replace in the future, but anyway 1440p 144hz at least. I find 4K interesting, but I don’t know if I’ll use it.
I like wide screens with a resolution of 1440p.

I would then like to play current games on high settings and max 144Hz if possible, but at least I want to get 60fps.

I can assemble the PC myself, no problem.
I can’t really set my budget. The computer should have enough power for my needs, but it shouldn’t be unnecessarily large.

My current thoughts: https://geizhals.de?cat=WL-3089480&hloc=at&hloc=de&nocookie=1

Maybe quite large.
I still have a 500GB M2 SSD from my old PC, which I still use for the OS and drivers.
I absolutely need WiFi on my motherboard ☺️

I don’t want to buy AMD hardware.

I will be very happy to receive feedback.

Have a nice Sunday!
