Shutdown the machine.  Boot using a live USB stick.  Type notes into a 
text file.  Use script(1) to record console sessions.  Use dd(1) to take 
an image of each disk to an external HDD (consider piping dd(1) to 
gzip(1) to save space).  Shutdown.  Take note of which HDD is cabled to 
which motherboard port.  Replace motherboard.  Connect HDD's to the same 
motherboard ports.  Boot.  It should "just work".


Post details if you have problems.
