This thing is meant for a living room media center. A prebuilt PC with discrete GPU is a much bigger profile (and probably cost). You could say, fine, go buy a small Mini PC. But a system with the current best AMD Strix 890m GPU not only is expensive at $700-1000, but would only have half the performance of the Steam Box if its conjectured performance is similar to an RX 7600.
