PCLinuxOS has a 'remaster' facility which enables you to create a new installation CD based on the installed software and configuration of the current setup. I've no idea how well it works, but I've seen plenty of references to it on their forum. I rather suspect though that it only includes system configuration, not personal user settings (but I might be wrong).
Failing that, I suppose that you would have to manually partition each PC hard disk in the same way as the master one, then find a way to copy all the files across, complete with symlinks (which might be a problem). The best way would be to ghost each partition using Ghost-for-Linux or something similar. If you want to preserve a dual-boot situation, you would then need to run the live CD and use it to repair the master boot record.
Assuming that the hardware isn't identical, there might be some issues booting the OS on different hardware, but Linux is pretty accommodating in this respect so it would probably work but maybe need a bit of tweaking afterwards.
To be honest, I wouldn't even bother trying the second method. I would be concerned about losing the remainder of my hair. The remaster method looks to be by far the best option.
