The extensive upgrade covers proprietary hurdles like replacing the stock PSU with a 500W HP unit (due to non-standard power connectors and lack of PCIe cables) and overcoming form factor limitations by installing an AIO liquid CPU cooler and custom-designed 3D-printed fan brackets for improved airflow. The final build features a powerful Radeon RX 6700 XT 12GB GPU, 32GB of DDR4 RAM, and an NVMe SSD, all while adhering to a strict rule: ensuring the PC remains physically undamaged and fully reversible to its original state. The video concludes with stress tests and gameplay benchmarks in titles like God of War Ragnarök to prove the concept's performance viability.
