I'm planning to build my first PC and would appreciate feedback on whether these parts work well together and whether there are any better-value alternatives:
- CPU: Ryzen 7 7800X3D
- GPU: Radeon RX 9070 XT
- Motherboard: Gigabyte B850 Aorus Elite WiFi 7
- CPU cooler: Thermalright Phantom Spirit 120 SE
- Memory: 32GB (2×16GB) Silicon Power DDR5-6000 CL30
- Storage: Crucial P310 1TB PCIe 4.0 NVMe SSD
- Power supply: MSI MAG A850GL 850W
- Case: Lian Li Lancool 207
Are there any compatibility, cooling, airflow, or pricing concerns I should address before buying everything?

The Lancool 207 is a good case, but make sure you add a rear exhaust fan. Even an inexpensive quality 120mm fan should improve airflow and temperatures noticeably.
The parts are generally compatible and make for a strong gaming build. The 7800X3D, RX 9070 XT, 32GB of DDR5-6000 CL30, and 850W power supply are all sensible choices. The Phantom Spirit is also more than capable of cooling the CPU.
Depending on local prices, you could consider a less expensive B850 board unless you specifically need the Aorus Elite’s extra features. The savings could go toward a newer Ryzen 7 9800X3D, if the price difference is reasonable. I’d also compare the Crucial P310 with drives such as the Patriot P400 Lite or WD SN5100, since they may offer better value.
Just to clarify, your memory kit is 2×16GB, so you already have 32GB total. That’s enough for current gaming and won’t normally be a bottleneck. You don’t need to upgrade unless you’ll also be doing heavy productivity work or running lots of applications at once.
