While this new 3500X ARGB Mid-Tower PC case isn't shipping yet (backordered until the end of July 2024), it looks to be a winner based on my experience with Corsair products. Looking for a new case that supports the iCUE infrastructure? This one might be the ticket for your new AMD 9000 series CPU build. And I might note that it includes three ARGB fans and supports the back-connect motherboards, at least those from MSI.
As Albert Einstein said, "I could have done so much more with a Big Al's Computer!".
