[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.
