I just got my Mac Mini and want to free up as much space as possible by reinstalling the OS. When I reinstall the OS, do I have a choice as to which apps to install (ie. GarageBand, iTunes, iWeb, etc...)? Will it completely wipe the hard drive for me when it does this, or will there be random bits here and there that remain after a reinstall? Finally, how much space would I ultimately save by not installing the extra languages, printer drivers, and a couple of the apps? Thanks!
