[CentOS] customized centos 5.4 install, core install?

Hello,
This might be called a core build not completely positive. What i want
to do is make a completely customized centos 5.4 unattended CD or DVt
not only installs a specific list of apps apps that i want on each
system, but configures them automatically perhaps via scripts, and
enables or disables services etc. Basically, i want to drop the CD or
DVD in a box which will probably not have a monitor anyway, and walk
away. I then come back or ssh in and everything is already installed,
any repos are added, configured and ready to go. Is this a core build?
I'd appreciate any pointers on this.
Thanks.
Dave.
