Help me finish my planned PC build!

I'm planning to build a new PC by the end of the month, and I need some help finishing the rest of it.

Use case for this build would primarily be gaming, with some frequent photo and video editing.

These are the parts I'm already settled on (and already in the process of getting them)

CPU: Ryzen 7 7800X3D

GPU: AsRock Phantom RX 6800XT

Storage: Silicon Power XS70 2TB | Silicon Power UD90 4TB

Case: Fractal Design Fractal North Mesh

Cooler: Deep Cool AK620

I need help with getting the right PSU, motherboard, 32GB RAM combination. Additional case fans are also welcome, if they would help with my system overall. Budget for the remaining parts would be around $600.

I'd prefer parts with no RGB if it's even possible these days, since the side panel isn't see through anyway.

As for future-proofing, I'd probably start with adding more RAM sticks, and a GPU maybe 5 years down the line.
