I've selected most of the parts for a new gaming PC and would appreciate feedback before ordering. I'll probably buy from Amazon US and ship to Qatar, since ordering from the UK appears considerably more expensive. The current parts list includes a Ryzen X3D processor, a high-end graphics card, and an 850W power supply. I'm mainly trying to choose between a quality air cooler and an AIO, along with a compatible case that has good airflow and supports the radiator if I go with liquid cooling.
My remaining budget is roughly $300–$500, although spending closer to $300 would be preferable. I like glass "fish tank" cases, but I don't want an unusually wide design with the power supply hidden behind the motherboard area. I'm prioritizing CPU cooling performance, reasonable noise levels, and value. I'm especially interested in cases that can mount an AIO radiator at the top or rear. Since shipping a case to Qatar may be expensive, I'd appreciate several options in different price ranges and sizes so I can check local availability.

For the parts already selected, the 7800X3D is worth considering if it is substantially cheaper; it is only a little slower than the 9800X3D in many games. The motherboard looks reasonable, though a Gigabyte B850 Gaming X could potentially save some money. RAM with the same capacity, speed, and timings will perform similarly regardless of brand, and the Samsung 990 Pro is excellent but not essential. A less expensive drive such as the Crucial P510 may offer better value.
The Ryzen 9800X3D doesn’t need an AIO for normal gaming. A Thermalright Phantom Spirit 120 SE is inexpensive and performs close to the top of the air-cooling market. An AIO is mainly worth choosing for the appearance, or if the PC will regularly be running in a very hot room above about 30°C. If you use a dual-tower air cooler, low-profile or non-RGB memory is safer because tall RGB heat spreaders can interfere with the front fan. The clearance can be tight, although the front fan can sometimes be raised slightly if the case has enough width.
An 850W PSU is a sensible target, but don’t choose purely by wattage or brand. Check the exact model’s reviews, protections, efficiency, warranty, and whether it includes the proper modern GPU power connector. Some inexpensive units have poor internals and can be dangerous, while quieter, high-quality models may cost less than heavily marketed premium options. The RX 9070 XT also offers performance close to the RTX 5070 Ti for much less money, unless you specifically need CUDA or prefer Nvidia’s DLSS features.
Choose the case based on radiator support, GPU length, cooler height, and airflow rather than brand alone. A well-ventilated glass case with a mesh front or side intake and a top-mounted 240mm or 360mm radiator would suit your preferences. Check the exact dimensions carefully, since some attractive fish-tank cases have restricted airflow or are much wider than they look. If you use an air cooler, make sure the case supports its height and leave room around the memory slots.

That makes sense. I like the cleaner look of an AIO, but if a good air cooler is much better value, I’ll compare the total case and cooler cost before deciding.
