Valve's Steam Machine is upgradable, but not where it's wanted most

Valve's Steam Machine is designed to be upgradable, but the upgrade options are limited, particularly in terms of the GPU. The system features a custom GPU board that is not easily replaceable, making it challenging for users to upgrade this crucial component. While other parts like the CPU and RAM can be upgraded, the lack of GPU upgradability may hinder the system's longevity and performance potential. This limitation could impact the appeal of the Steam Machine for users looking for a more customizable gaming experience.
