You can do that, but it is difficult if possible at all to convert an 
existing filesystem to raid1 and there would be a small performance hit 
if you plug both IDE drives into the same cable. The straightforward 
approach would probably be to create the raid on the new drive, 
specifying the other member as 'missing', copy everything over and 
adjust fstab and grub.conf to use it, then add the old drive and let it 
sync.  Geeks.com has a refurbished 160gig that might last as long as the 
rest of the computer for under $50.
