A modder known as TheJiral on Reddit has created a fanless, retro-futuristic mini PC featuring a substantial heatsink and an external SSD enclosure powered via two USB 4 ports. Central to this build is the ASRock Industrial Box-7640U Mini PC, initially equipped with a smaller fanless cooler. The heatsink has been upgraded to a Wakefield-Vette PADLED-13080, sourced from DigiKey. The original case has been replaced with a 3D printed one, incorporating side vents and threaded inserts instead of self-tapping screws. Although the specific 3D printer used is unknown, it appears to be an FDM (Fused Deposition Modeling) type, likely one of the top models available.

Performance-wise, the build is based on the ASRock Box-7640U, which utilizes the low-power Ryzen 5 7640U CPU. This processor is designed for laptops and is less powerful than the Ryzen 7 7840U but still offers strong integrated GPU performance with its 8 RDNA3 Compute Units, compared to the 12 RDNA3 CUs of the 7840U. The Radeon 760M iGPU in the Ryzen 5 7640U ensures decent graphical capabilities. TheJiral claims that their chosen cooler can handle the Ryzen 5 7640U at 28 Watts near full utilization effectively. They also experimented with an overclock option on the ASRock motherboard, enabling a 45 Watt TDP performance mode. However, this caused the system to overheat during CPU stress tests, indicating that overclocking is not feasible with this fanless setup. Adding fans could potentially make overclocking possible, but it might compromise the aesthetic design.

Additional details about the build are available in the original Reddit thread, although specific information about the custom shell's creation and inspiration is not provided. Given TheJiral's recent 3D printing project themed around Settlers of Catan, it is plausible that the retro-futuristic mini PC components were produced using a similar method.
