Acquired an iBook G4 yesterday. It's in pretty good condition. The battery is probably in need of replacement, but good luck on that.
But the hard drive is still OK ... although I am seriously considering getting a 512GB M.2 NGFF SATA drive and sticking it in there ... there's adapter sleds that work.
Might be a bit overkill, especially for a system with 1.5GB RAM max, and 1.33GHz speed.
But who am I to balk in the face of absurdity and not do it?
I look at it this way ... the upgrade will be good for my iPod (orig 2nd Gen) which I plan on hooking up to the system instead of crappy flaky Windows FireWire support. Once upgraded, and I also get the battery replaced in the iPod, I'll be super happy to have a 2005 era setup again :3
