Heya. New here. Need some advices for building a PC.

So, I've done quite a lot of research, still doing so, but some things are overwhelming my mind and making it hard to decide. First time building a PC, my budget will be 2000€, and I made the decision of using the following parts so far:

-Ryzen 7 7800X3D -RX 9070 XT -FOIFKIN M2 Case

It's not 100% fix decisions, because, well, I'd love some second opinions since these were recommendations from a fella who built PCs longer than me. I was wondering if I should spend some extra cash and go for Nvidia or not? Should I go straight for 1000W PSU or is that overkill? My main goal is mainly gaming at 1080p, and a pc that will last me at least a decade if not more. I already have a gaming laptop, which is already showing signs of failing after 1 year (judge me if you must, I know it was a terrible investment now). Should I use AIO or stick to Air Cooling? I've seen both and both seem cool, I kinda lean towards AIO cuz it looks rather nice, but I'd rather use something that is silent and cools my CPU and GPU just fine. My aim for Gaming is High graphics, not Ultra, at 144 FPS or higher. Peripherals are not necessary at the moment, I have those three sorted already. Any advice or tips are very welcome. I thank every single person for their time and advices in advance! Cheers.
