What document can justify the replacement of the server?

Question

Iron

There is such a basket with blades - Intel MFSYS25 . It is clear that a very respectable age. There are a lot of places on the Internet where it is mentioned that the service life of a server is five years. Is there a white paper to refer to? (You do not need to give a link to depreciation rates :))

Money-makers understand numbers
Give them numbers on how much it costs to use this server now: electricity, maintenance time, downtime losses
Give them numbers on the equipment that they need with those numbers
Calculate the payback period
