There is no uninstaller for OS X.  There was an unofficial unsupported 
AppleScript from Apple that would throughly uninstall OS X 10.0, but they 
didn't updated it for newer versions of the Mac OS.

You are correct that trying to uninstall OS X via drag and trash will 
leave hundreds of invisible files untouched.

Your choices are to upgrade the version of OS X on your drive to a newer 
version, or to backup up your drive, erase it, and then to restore your 
data and files, but not OS X.
