I have to partially agree with Chris here.  You're now
talking about an integrated SCSI controller on the mainboard,
not my idea of "ideal."  So now you're putting more
constraints on yourself.

Agreed.  Until the system has an _off-mainboard_ storage
controller, then you're not going to be able to replace 1:1.

At first, I thought you were just talking about having a
"light mainboard/CPU/memory" as a backup.  You would then
have an extra storage controller on-hand as well.  That would
work.

But now you're got hardware dependencies in the mainboard
itself, especially the storage controller.  _Not_ good.  That
makes it difficult to bring up a replacement system by merely
putting in the exact same storage controller, and moving the
disks over.

Agreed.  That's why I suggested you have the "emergency
hardware" _on-hand_ in the first place, to verify you can
replace it out.  Again, it's worth the $200 to do it _if_ you
have an extra storage controller on-hand (which you should
anyway) *AND* you can move over the storage itself.
