Granted, it's a little rough around the edges but this DIY PC manages to use two Noctua NH-P1 as CPU and GPU cooler. Featuring the Ryzen 5 5600X, the Radeon RX 6600 graphics card, and the tiny SiverStone NJ450 fanless power supply, temperatures never exceed 85°C. We'll ignore the unconventional mounting system, and by unconventional we mean zip ties.
