I have to 2nd Chris' notion here. Anytime you have 3 or more
systems, the cost to procure a spare is not much of an
additional cost -- especially without fixed disk storage
(which is typically the majority cost of any system).
One set of a spare, pre-assembled enclosure (including
hot-swap disk), mainboard, CPU(s), memory, NIC(s) and storage
controller(s) is always a good move when downtime is to be
avoided at all costs (without breaking the bank on a failover
implementation).

Yep, make the spare ready-to-use using existing storage.
Once you have the system back up on the new "shell," you can
always go back and debug the failed "shell." In the worst
case, it now becomes your "spare parts" system.
