That looks nice for your first build. I was browsing the comments but it was yet to be brought up, so here it goes.

Whenever you can, and if your PSU has available slot, try and use another PCIE cable going from your power supply to your RX 7700 XT. A single cable powering it might be fine for now but it can be taxing to the cable once you overclock or really pushing the GPU to the limit.

Nonetheless, great job dude.
