What I would do is this:

used G4U to clone the other machine if it is identical,

http://www.feyrer.de/g4u/

G4U works very well, and boots Free/NetBSD, it boots from CDROM, and 
backs up to an FTP server which you will have because you have the other 
machines.

Then G4U boot the new machine and slurp the image back down....

This may work, its slow to create the images and needs a lot of disk 
space on the ftp server, but slurping the data back is fast....

This would give you an image of the install which you can use for DR as 
well...
