Yes I have a system backup of the last time I did any rpm updates, its wither sme is robust enough not to change anything if I do an update if I just move the disks to another box.
Older athlon Mb with a max processor of 1.4Ghz to a new nforce job with everything built in.
I have a multi disk setup as I use my sme to stream media along my local network and have 2x160Gb of media and 1 80Gb with user directories on it.
