I'm planning my first desktop PC for gaming, university work, and streaming. My budget is under €4,000, and my current parts list comes to roughly €3,500. I'm considering 64GB (2×32GB) DDR5-6000 CL30 EXPO memory, a Ryzen 7 7800X3D or 9800X3D, an RTX 5080 16GB, a Thermalright Peerless Assassin air cooler, an AM5 B850 motherboard with Wi-Fi and Bluetooth, a 2TB PCIe 4.0 NVMe SSD, an 850–1000W ATX 3.0/3.1 power supply, and an airflow-focused case such as the Lian Li LANCOOL 216 or be quiet! Shadow Base 800 DX. I'm located in Germany and would appreciate advice on compatibility, the amount of RAM I actually need, SSD heatsinks, air versus liquid cooling, whether larger or triple-fan coolers are worthwhile, and whether a Gold or Platinum power supply makes more sense.

For the case, the LANCOOL 216 is a strong airflow-focused option and its large front fans should work well. Add dust filters and clean them regularly, especially with cat hair around. Two additional low-speed bottom intake fans can help feed cool air to the graphics card, but they are optional. Pick a monitor based on your budget: 1440p is a good balance for high-refresh gaming, while 4K makes more sense if you want maximum image quality and are comfortable spending more on the display.
Gold versus Platinum mainly describes efficiency, not build quality. The real-world difference is small, so a well-reviewed Gold unit is usually the better value unless your PC runs at high load constantly or electricity is particularly expensive. Prioritize a reputable model with modern GPU power connectors and appropriate protections. Also choose a reliable TLC-based NVMe SSD for the operating-system drive rather than focusing only on the advertised sequential speed.
The Ryzen 7 9800X3D is the stronger choice if the price difference is acceptable, while the 7800X3D can offer better value. An RTX 5080 is suitable for high-refresh 1440p or 4K gaming and streaming, but compare its German pricing with alternatives because the extra cost may not match the performance increase over a slightly cheaper graphics card. Your 850W supply is likely sufficient if it is a high-quality ATX 3.0 or 3.1 model; 1000W is fine if the price difference is small, but it is not mandatory.
For gaming, 32GB of DDR5-6000 is generally enough. 64GB is reasonable if you do heavy video editing, run virtual machines, use demanding creative software, or want plenty of headroom for streaming and multitasking, but it will not automatically make games faster. DDR5-6000 is a good target for AM5, although extremely tight timings are not essential with an X3D CPU. A dual-tower cooler is already plenty; a triple-fan design usually refers to the graphics card, where it can help with noise and temperatures but does not necessarily improve performance.
The parts should be compatible, but check the exact motherboard model and confirm that it supports the chosen CPU with the available BIOS. The motherboard’s built-in M.2 heatsink is normally sufficient, so you do not need to buy an SSD with its own heatsink. A Peerless Assassin-class dual-tower air cooler is more than adequate for either X3D processor and will usually be quieter and simpler than an AIO liquid cooler. Liquid cooling would mainly be a choice for appearance or case-clearance reasons, not because this CPU requires it.
I was mainly thinking that more fans or a liquid cooler might prevent the high temperatures I’m used to seeing on my old gaming laptop. I’m still unsure whether 32GB or 64GB would be more sensible.
