    How do I do that? I know I can do a clean install, but just so everything is gone even the OS, how do I go about doing that? Thanks guys.

    Boot off of the OS X and run Disk Utility to wipe the drive.

    You can restart and eject the disc after that.

    Re: Disk Utility. If you've got personal details, bank details etc. a 7x write zeros should suffice. It'll take some time though; leave it running while you're out for the day.

    Boot off the OS X DVD/CD by holding down C as you restart the machine and run Disk Utility from the menu before installing OS X.

    use the disk utility and the erase free disk space option

    Depending on how secure you want it you can choose zero-out, 7-Pass erase or 35-Pass erase
