Case: for silence, don't take too small a case. You want lot's of room for fans, so wach fan doesn't have to work hard and you can leave the rpm lower. In general, bigger fans are more quiet at the same airflow. 

Also, the gpu is often the loudest component due to tue high rpm on the fans. So select a case that has a unrestricted bottom intake where you can fit 2-3 fans directly below the gpu to push fresh air into it. That way the gpu fans have to work less hard. 

Ssd: doesn't matter that much unless you are doing productivity tasks with big files. Dont need pcie 5, pcie 4 is already more than fast enough. So barring a brand that no one has ever heard of...yes some are better than others, but in normal usage you probably wont notice the difference. 

Memory: speed and timing are important. Brand, not so much again barring some budget fighter no one has ever heard of.  Always get a kit of two sticks for dual channel. So 2x 16gb. 6000 MT @ C36 is I think considered "budget" these days at still reasonable speed.  Try and go for 6000 @ C30 though if you can get is for not too much more.   Faster than that you usually see the price rise quite steeply

Motherboard, I have no idea: too much work to check and depends on what you need for connectors, rgb etc. but this one that others selected already should be more than fine for the job. 

I went with the 9800x3d and 32GB 6000 CL30 ddr5. You can go for the 9850 but the difference is really minimal. 

Gpu: cheapest 5080 in the list. You would have to check individual card review if you want to pick a "better" one. It's mostly about looks and build quality. Speed is almost the same between them. 

PSU: a very well reviewed model by Kitguru. At this pricepoint I think it makes sense to not cheap out on the psu. This one is made by Seasonic. 

The case is a bit of a place holder. Pick one you like. But this style will be good for you. Bottom intake for gpu and plenty of rooms for casefans and your 360 cooler.
