Give it away to a Charity, maybe even a small private school or college.
Maybe turn on a younger family member (or a friends kid) to Macs, and give it to them?
Even if it's just for messing about on the net...
Yeah I was thinking of giving it away. But a school wouldnt even want it as its so out of date. I'll give it to a charity and they can sell it or do with it what they want
