You are thinking too technically-minded.  This is a business decision,
not a technical one.  Numbers on how long components last are
irrelevant to this conversation.  The only point that needs to be made
is that a failure can be expected, and to plan business operations
around that.

Another point in this is that no matter what they do, there is a cost
to maintaining an infrastructure.  Buying new servers does not
eliminate the risk of hardware failure, and doesn't necessarily delay
it either.  These kind of plans should be in place with the new or old
servers.

Also, when I say "describe what would happen", I'm not talking about
how a board might blow a capacitor, I'm talking about how you will
react and what the impact is on the business during that time.
