I want a new PC in the foreseeable future, so here I am asking for advice

Here's some basic info about my current build
-Processor: i7-7700
-RAM: 32 GB DDR4 (originally they were 16GB, but one module died and I had to buy new ram modules)
-Graphic Card: RTX 3060 (originally it was the GTX 1060 3GB but it died too)
-Motherboard: Asus Z270H
-Case: Zalman Z11 plus. I hate it, it's ugly, I did not chose it (they didn't had in stock the one I bought and gave me that one instead) and cleaning it is a pain in the ass

I'm planning in changing teams, leaving Nvidia, Intel and Windows behind for AMD and Linux

I can't afford a high end PC, but it will be a gaming PC, so let's stay in the middle (more or less in line of what my current build was 6-7 years ago)

The thing is Idk much about AMD (I've been inside the Nvidia bubble for too long), are they going to launch new hardware (procesors and graphic cards) soon? should I wait? will the wait be worth? (yeah, sorry. those are the eternal questions, I know never is the right moment to upgrade)

I DON'T have any interest in most AAA graphic intensive games (like GTA VI) there are some exceptions, (like the next Monster Hunter) but I rarelly play AAA games (In general I'm more into a A or AA games) so here it is possible to cut some corners a little

Ok, those questions were a little bit generic and I can investigate on my own, you can ignore them, but I have some questions a little bit more specific

I have a PCIe 3.0 NVME M.2 SSD and a Samsumg EVO 870 EVO (Sata 2.5'') I'll like to reuse in the new build. would it be possible? are new motherboads (with PCIe 5 or 6) backwards compatible? (asking about the M.2 SSD that uses PCIe 3.0 mainly, the other one is a normal Sata SSD) I plan to buy a newer (and faster) M.2 SSD too, but the extra storage is always welcome even if it's slower

About the case I just want a simple case, easy to clean and as silent as possible (so the bigger the fans the better) with plenty of room inside so it's easy to work with it when I need to do some maintenance like cleaning or replacing something, I don't need RGB nor a glass window nor all the fancy stuff so what do you recommend?

Another dilemma I have is the screen, it's so old it it only has a DVI port!! (SyncMaster BX2335) but still works, is full HD and its size is 23'' I don't have room for a much bigger screen so idk if 1440p or 4k screens are worth, tbh.
