This comes down't to the old question of "what is a server"?

Is a server,
a) the most powerful, reliable, expensive computer equipment on the planet?
b) a machine that serves something to other machines, i.e. a web /
database / email / backup / print / etc server?

And does it mean that if the motherboard is not a Titan / SuperMicro
board, it's not a server? Come on, that is BS! My 15 year old Pentium
I PRO (Socket 8 CPU), still serves very well as a firewall, and will
boudle back as a file server at any given moment. In fact, I think
it's far more stable than many Dell servers I have worked on. Just
cause a company like Dell or SuperMicro builds expensive components
and offer a 4 hour support structure does not make them superior to
other computer components.
