A lightning strike caused a power surge that damaged my mother's 5-year-old G4/1.33 MHz Mac Mini, currently running Tiger. I think I'm going to get her a new (or refurb) one for her birthday (shh, don't spoil the secret! ) Once I do that, I'll probably inherit her old computer. Is there anything that can realistically be done with a stock (512 MB, 40GB hard drive, no Airport) G4 Mac Mini? That happens not to have a working Ethernet port? (although we have a USB-to-Ethernet adapter.) It's well out of warranty so I have no problem futzing around with it -- if it breaks, it breaks -- but I'm also reluctant to put too much money into a device that old.
