Priced at $1,299 upon its release, the Power Mac G4 Mid 2003 instantly captured the attention of consumers with its blend of performance and affordability. However, Apple’s strategy of concurrently releasing the 1.25 GHz Power Mac G4 model alongside the groundbreaking Power Mac G5s added a layer of intrigue to the market dynamics.
