You'll probably be stoped by a kernel panic error

my e-smith installation can detect changes in the nics, i've replaced them without troubles to reconfigure e-smith, but hdd is a problem.
I have made a few tests on this without luck, beter than this could be a reinstallation disk, and a desktop backup of a working e-smith, then you can powerup a new machine and begin a re-installation process that will detect hardware, disk size etc, and you'll get a new clean machine where you can download a desktop restore of your old system.
