Try 'du -sh /root /lib* /usr /var /tmp' is a good start. /root should
be small, but can pick up cruft. In your case probably not since it's a
self-adminned system using sudo :). Normally I would also include /boot,
but if you removed old kernel packages that should be rather small.

Most likely you'll be cleaning out /tmp if you don't boot very often or
something in /var.
