I'm considering using such a setup. And if I decide to give it a go, 
I'll have to backup, boot from a custom CD I made, make the changes to 
the disks and restore the backup. Considering that, trying out what unit 
is used, should only take a fraction of the total time, and it doesn't 
really scare me to try it. :) I realize my question went to the wrong 
person, but I simply replied to the mail. My apologies.
