I have the opportunity to pick up an old used TiBook with a dead HD for not too much. And I happen to have a spare notebook drive laying around, so I figured I'd turn it into a jukebox machine or something. Or maybe just sell it. Or whatever. Is the ram upgradeable? (I already have to open it up to replace the drive, so I can do the ram at the same time if necessary.) If so, how much will it take? I have two 1GB sticks from a G4 aluminum powerbook sitting around; will those work (even just one)? Is there a limit to HD size that I can put in (not the physical size)?
