it's the FC array or SAN where much of the money goes. these things
aren't cheap even before you start buying lots of disks to put in them,
entry level price was over $100K last time i looked (admittedly, over
two years ago - a long time in the computer industry).
and it's not an expense that can be avoided - skimp on the I/O, and the
whole system will run like a dog.
the actual servers are, as Con said, cheap - well under $5K each....and
as little as $1K for the MX/MR/web-server boxes (having solid-state
disks for the MX boxes would at least double that). it's got to the
point where you pay almost as much for the 1RU rackmount case to put all
the bits in as you do for the bits themselves.
you can buy a LOT of machine these days for $2 or $3K. you can buy an
amazing amount of machine for $5K.
there's also salary costs - yes, the FOSS world does have all the pieces
to make fantastic mail systems, but it does take time to put it all
together, from initial design to choosing the exact software selection,
to installing, configuring, and testing it and then revising your
original design in the face of reality (repeat the last two steps until
satisified with the result).
i still think my (very rough) guess about price is reasonably accurate.
