What do you remove from a default Mac OS X install? [closed]

Is there anything in the default Mac OS X install that you like to remove for performance, clutter, or non-use reasons?

I have done custom installs without all the extra print drivers and language support, but other than that, I find most default Mac OS X installs pretty clean cut.

Solution 1:

OS X as well as some of the applications come with built-in support for a ton of different (human ;-) languages that you probably don't want to use. You can remove the localization using Monolingual. On my machine Monolingual saved a total of 1.8 GB.

Solution 2:

The two programs I remove are the Microsoft Office and iWork demos
