It will work, almost certainly. Maybe you won't have the most optimal
system after the replacement (eg running a i586 kernel on a i686, or no
smp kernel (multiprocessor, also used dor hyperthreading and dual core
cpus).

Not very hard, run system-config-display , which is essentially the same
utility that is used during fedora's installation.
If it doesn't run at all, remove /etc/X11/xorg.conf and rerun
system-config-display.

One thing that caused me problems in a similar situation was when the
old system had an onboard network controller, as well as a pci network
card, and the new hardware had just one network card. The boot sequence
was hanging forever trying to initialize the non-existent eth1. But that
was of course easy enough to fix from runlevel 1.
