I have a three year old eMac (1.25Ghz, 512Mb RAM, 40Gb HDD).
It'll be a year before I can afford a new Mac, so I'll looking to improve my eMac to improve its longevity. Don't have an enormous amount of money to spend though (otherwise I'd have an Intel iMac by now ) but enough I guess for reasonable upgrades. Not able myself to upgrade the computer physically but I have the help of my father who is an electronics expert and could handle things.
Any suggestions? I think the HDD is the main one as I have to use the disk repair tool once a month.
