Hello all, long time lurker, first time poster... Last year, my mother got a Mac Mini, which has been perfectly adequate for her needs. But since then, her older Mac has been untouched. Its specs, as I see them on the back: G4/500/1M Cache/256 SDRAM/27 GB HD/DVD-RAM/ZIP/KB I think this is better than the purple iMac that I've been bumbling along with, but that's not saying much. Still, I wonder if it would be cost effective to try to upgrade this computer for myself, for uses like word processing, web surfing, iTunes, light use of iPhoto (no major photo manipulation), and iTunes. I've visited www.lowendmac.com, but I'm not absolutely sure what kind of Power Mac this is, so I'm probably not searching in an effective manner. Thanks in advance for your help!
