All good except RAM.

You want RAM to be 6000MHz but with the lowest timings possible, CL32 or less (CL30 recommended).
No point going over 6000MHz on Zen 4 based systems as some parts inside a CPU cannot run at 1:1 with higher RAM speeds.
Have a look here:
AMD's Ryzen 7000 Zen 4 CPUs appear to have DDR5-6000 as their sweet spot, allowing for a 1:1 IFC ratio. A 1:1 ratio indicates that the memory operates at the same frequency as the memory controller o...

I found a few examples of the "perfect" RAM for that system.
I hope it helps.
