Great Wall introduced the Archimedes KM18 case on July 7, 2024, offering a budget-friendly option for builders who need a sturdy chassis without spending much. This release matters because it provides a low-cost entry point for Mini-ITX and Micro-ATX builds that still require robust cooling and component support. Buyers looking for an affordable base for a compact or mid-sized PC should take note of this new addition to the market.
