Carbon Copy Cloner Good program. You unlimited testing, but if you use it, pay the guy 5 bucks per licence,or at least 5 bucks.
The program works for me.
This is not a net-boot option, rather it creates a boot able clone that can then be replicated across all of your machines. CCC has saved my ass a few times. If you don't have an external drive, you might want to bring up each machine in
Target Disk Mode. Best pratice would be this, Set up one machine so that it is the way you want it. I would highly recomend formating the drives before you clone to them.
Scratch this, if your running OS9, this won't work and you can TD mode the computers.

You could remove the "master" drive and all of the others, and use CCC in conjunction with a
Cables Unlimited USB 2.0 to IDE Cable with Power Adapter. I picked up one at TigerDirect for 15$us (screw their rebates-bastards!) sans rebates. It would be a good try.
