Hey everyone, (First post, yaayy!!) So, a little while ago, I came into possession of a 2002 Powermac G4 MDD (M8570) and until recently it's basically just been sitting around collecting dust so I figured it's about time to make something out of it. The machine works just fine, but it's only able to run up to OS X 10.5.8 which, as we all know is pretty outdated. However, I'm a college student which means I'm pretty much broke most of the time and therefore, I've gotten pretty good at salvaging parts from junk electronics and computers to fix other stuff - so what I'm wondering is this: Is it at all feasible to try salvaging functioning components from other Apple machines like iMacs, Mac Minis, or even MacBooks (that support more current OS versions - ideally macOS Sierra) that I can find/buy super cheap and somehow retrofit or modify to work inside the case of the G4? Basically, I'm not into gaming or super fancy case aesthetics - I just want a Mac-Only Desktop machine that communicates well with my other daily-use Apple products but has enough room inside to support the memory I need, the HD storage I'm looking for and the "aerodynamics"(?) to keep it all cool. If anyone has ever heard of or done such a project, I would greatly appreciate whatever help I can get!
