A tech enthusiast has documented the creation of a custom, compact AMD-based FreeBSD desktop, demonstrating a DIY approach to building a small form-factor PC with older-generation hardware. The builder repurposed an AMD Ryzen 4750GE CPU from a previous failed project to avoid the high costs associated with newer DDR5 and AM5 platform components. This 35W TDP processor provides 8 cores and 16 threads on the mature AM4 socket, offering a practical balance of performance and power efficiency.
The new system is housed in a Silverstone SG13 Mini-ITX case, which measures just 10.8 liters in volume. This represents a tiny 5% increase in size compared to the previous build's SG05 case, yet it was necessary to accommodate updated components. The builder prioritized a minimal footprint, selecting the case after an extensive search for a chassis that was both exceptionally small and feature-complete.
Performance-wise, the rebuilt desktop delivers a significant upgrade. The CPU provides approximately 25% faster processing speeds than the previous system. The graphics department sees even more substantial gains, with performance improvements ranging from 40% to 60% depending on the specific workload. Storage and memory performance remain similar, as the build continues to use the same AM4 platform with DDR4 RAM and NVMe/SSD storage.
The assembly process, completed over a quarter after acquiring the parts, became a hands-on project involving the builder's son. A major challenge emerged during GPU installation: the designated graphics card, nicknamed "Challenger," physically would not fit into the tight confines of the SG13 case. This required creative problem-solving and modification.
To resolve the fitment issue, the builder first meticulously cut about 1cm from the plastic fan shroud to align it with the card's PCB. When that proved insufficient, a more drastic measure was taken: the metal expansion slot bracket itself was removed and trimmed. These modifications were successful, allowing the Challenger GPU to finally be mounted to the motherboard.
The final assembly included installing RAM sticks, a SATA SSD, and a Thermaltake Toughpower Grand 750W power supply with detachable cables, which helped with cable management in the cramped space. The project showcases the viability of building capable, compact systems using cost-effective, previous-generation hardware and the ingenuity required to overcome physical constraints in small form-factor builds. The completed computer, aptly named "Challenger," is now ready for use as a FreeBSD desktop.
