This is true.  I've also taken an existing Fedora installation and upgraded 
MoBo and CPU (even with new memory and CD drives) without a hitch.  (This has 
*never* gone well for me with windows. Linux ROCKS!!)

However, if you have the time, and you feel your configuration data is 
critical it is really a good idea to take the time to do some pragmatic 
backups and write down as much information as you can about your existing 
setup.  (I'm no heretic, but I just felt that someone had to say it.)

Of course, sometimes it's fun to refresh your memory by doing a fresh install, 
too.  I found with FC5 that things "just work" out of the box.

Let us know how it goes!
