I'm planning a new PC with an RTX 5070 12GB, Ryzen 9 9900X, 32GB of DDR5 memory, a 2TB NVMe SSD, an MSI B850-S DDR5 motherboard, a be quiet! Dark Rock 5 cooler, a Seasonic Focus GX-750 750W Gold power supply, and a Lian Li O11 Dynamic Mini V2 Flow case. Does anything look mismatched or unnecessarily expensive? I'm especially interested in whether the CPU, cooler, and power supply should be changed, but pricing and availability may also affect the choices.

I’d consider stepping up to an 850W power supply. A quality 750W unit should handle this configuration, but 850W gives you more headroom for future graphics-card upgrades and usually doesn’t cost much more. I wouldn’t jump all the way to 1000W unless you have a specific high-end upgrade planned.
The Dark Rock 5 is a capable cooler, but it may be relatively expensive compared with other air coolers that perform similarly. If you’re mainly gaming, a Ryzen 5 9600X with a B650-class board and a good budget air cooler could be a much more cost-effective setup.
The Ryzen 9 9900X may be more CPU than you need, especially if this is primarily a gaming system. A Ryzen 5 9600X or Ryzen 7 9700X can deliver similar gaming performance for less in many situations. The 9900X makes more sense if you’ll also be doing heavier multicore work, such as rendering or video production.
The parts look broadly compatible, but the best recommendation depends heavily on your use case, country, prices, and total budget. If the 9900X is heavily discounted, it can be worthwhile; otherwise, putting the savings toward a faster GPU, more storage, or an 850W PSU may provide more practical value.
