I'd like to clean up my G3 700mhz 55gb 10.3.11 for sale. How do I get rid of all my personal stuff, eliminate everything, then I guess reinstall what I want to go with the computer: the operating sys, perhaps Word, ILife. What's the best way to do this, to make sure there isn't anything left on the hard drive of mine.

Thanks.
