What case, motherboard, PSU, and cooler should I choose for an RX 9070 XT build?

Look for a case with three or more preinstalled fans, such as a Corsair 3500X-style airflow case, then select the motherboard and PSU independently. A B850 or quality B650 motherboard with Wi-Fi should work well. Also, 32GB of DDR5-6000 with low latency is a better target for a modern gaming build than 16GB.

The choice between an air cooler and an AIO isn’t mainly about climate. Room temperature affects both types of cooler, and a good dual-tower air cooler will handle these CPUs reliably without pump noise or liquid-related failure concerns. A 240mm AIO can perform similarly, but it isn’t automatically better.

Your monitor resolution matters. The RX 9070 XT makes the most sense for 1440p high-refresh gaming or 4K entry-level gaming. If you only play at 1080p, you could spend less on the graphics card, but with a $2,200 budget the 9070 XT is reasonable if the goal is higher frame rates and longer-term use.

Cases can include fans, but the motherboard and power supply are normally purchased separately. Power supplies bundled with cases are uncommon and are often low quality, so it’s safer to choose an 850W, 80+ Gold, fully modular unit separately. For cooling, a Thermalright Phantom Spirit or another good dual-tower air cooler is plenty for either CPU; an AIO is mostly for appearance unless you specifically prefer liquid cooling.

At this budget, the RX 9070 XT paired with a 9800X3D can fit comfortably, but make sure the rest of the parts aren’t overpriced. A sample build could use the 9800X3D, 32GB DDR5-6000 CL30, a 1TB NVMe SSD, an airflow-focused case, and an 850W Gold PSU. The 7800X3D is still a strong option if it costs substantially less.
