Even when the hardware is enough, I enjoy a new machine when it comes
to build a mail server: it is such a critical machine (users will not
understand that their mailbox could be out of reach for 5 minutes)
with enough different components, each having specificities on the
config (not the sort you power one and you are done) I don't feel at
ease doing too much modif on a production email server.
Now at 10K$ you have plenty of money, I believe you could afford 2
machines for hi availability.
