factory/brand new condition mac help

[mak]

hi,

i am going to sell my mac soon. i would like to know the best procedure to make my mac 'new' again and set it to the condition it left the factory in.

i have various important documents and files and want to make sure they are wiped right of.

can the computer be wiped 100% and thus leaving nothing behind? just being paranoid i suppose but i do want to pass on the computer with nothing of mine left on it.

can anyone assist?

thanks,

Boot into OS X from the DVD/CD. Use the Disk Utility to reformat the drive using the most complex method possible. (this will eliminate all data on it) If you're real paranoid, do this a couple of times. Re-install OS X from the boot CD afterwards. Make sure to do a thorough cleaning of the hardware. Canned air, and damp Q-tips are yoru best friends.

From the OSX startup disc restart computer. Under installer > open disk utility > select hard drive (not volume) > erase. Under "Options" select either Zero or 8 Way Random to be sure to eliminate all your data.
