Customized Linux Installations

edmz asks: "At work we have about 20 PCs which are all identical. We are planning on installing Red Hat on them but we want to fine tune it for the specific hardware that we have. We would like to install it and tune it on just one box and then somehow make an image or installation from it and store it in CD so that it can easilly be installed in the other machines. We would like to go the CD way, and I was wondering if there is any software that does this or if somebody knows an easy way to do it."
