Rather than performing 3 installs on our new servers, I thought I would try the trick of making a single install image and then deploying it multiple times. G4U, as mentioned above, did a great job of this (and is free!).
The only drawback? It was so slooooooooooow. But still, I could kick off the process and come in the next day to find a fully completed (and configured) install.
Another option for this sort of thing, besides G4U is PartImage. I may give that tool a try next time, though I can't imagine it'll be as easy to use as G4U was.
