Restoring Apple’s Final iMac G3: The Snow Edition Deep Dive

In this episode of CircuitSphere, we dive into one of Apple’s most underrated and rare vintage Macs — the iMac G3/500 Snow from 2001. This was the final version of the original iMac design before Apple transitioned to the flat-panel iMac G4. We’ll take you through a full teardown and rebuild using parts from two different machines, restoring this classic to its former glory. Watch as we upgrade the CPU, max out the RAM, replace the failing optical drive, and install a modern SSD for a major performance boost. Using SphereScale v2 benchmarks (Geekbench, Xbench, and Cinebench 2003), we evaluate how much of a difference these upgrades really make. You’ll see before-and-after scores and how this machine stacks up to other PowerPC Macs from the era. Plus, I fire up Oregon Trail II and Civilization II, putting this G3 to the test with some nostalgic Mac gaming. Spoiler: there’s chaos, wagon theft, barbarian uprisings, and some hilariously poor strategy choices. Whether you’re a vintage Mac collector, a retro gaming enthusiast, or just here for the teardown ASMR — this video has something for you.
