Our VM builds via kickstart take about 7 mins to build to a 30gb hard disk. How long would it take to copy a 30gb disk image across a network to a new server? I think much longer. Also if you have a corruption in the disk image it would get propagated to new builds? Real server builds take much longer, because of all the boot self tests, especially if you have a lot of memory.

Using a clonezilla image you should be able to build an image based system. I haven't looked into it deeply but if I recall correctly most of the hooks are there to do it.
Having built hpc systems in the vfx world, it is way easier to build using installers for the reasons highlighted earlier as well as when hardware changes within your cluster, it is easy to get a new one integrated in with a slightly different build or a few changed config lines to cope with the rewire of say the network or disk addressing.
Just my $0.02
