Building a new high-end gaming PC, how does this build look?

Hi, I'm working on putting together a high-end gaming PC and I've got a build going on here and I'd really appreciate any feedback/recommendations for the build

Here's the link to it:

I'm trying to be able to play any game out now and any future game for at least the next several years at 4K with at least 60FPS and with good performance

I FEEL like this is a pretty good build but ultimately I'm far from an expert in building PCs. I'm not sure if I've got a good selection of parts here and how well everything works together and how compatible everything is. Should I go with this particular MSI motherboard? Is 32GB of RAM enough? Am I good to go with gen 4 SSDs over gen 5 and is the Samsung 990 Pro a good choice? And do I need a separate SSD as the boot/OS drive and then a dedicated SSD for games? That's why this build has 2 of them: the 1TB for the OS and the 2 TB for games. Is there any harm in going with a PNY GPU over another brand? Is the case I chose a good one with enough room to fit everything and has plenty of airflow without needing to add additional fans? So many questions that I don't know the answers to! I just want to make sure that I have a good, well-functioning, compatible build going here before I start any spending

What do y'all think about this one?
