Securely selling, while keeping software

[JustDom89]

I am selling my old 12" Powerbook G4. When I bought it, it came with a bunch of software already installed. Is there a way I can keep all the software while securely deleting all my stuff?

Thanks

Clone it to an external.
Trash everything you want gone.
Boot from the new clone ('Option' on startup)
Using the Disk Utility on the clone, select the internal drive to be secured.
Select erase free space.
(memory hazy) write zeroes to disk in Security Options.

Also I want to keep Leopard..

All I have is the original install discs...which is Tiger I think..

are you trying to sell the computer with the software while keeping a copy of the software for yourself as well?
