pretty nearly any relatively "modern" (as in less than 5 years old)
machine will be more than capable of handling mail for 1000 users.

spend between $500 and $1000 USD on a decent new machine and you'll have
no problems.  pay attention to the brand/model of the motherboard and
the disk drive(s), they are the most important components.

this won't give you any crash-proofing or crash-recovery - for that you
need RAID 1, 0+1 or 5 disk (it's the only form of "backup" that is any
use at all for extremely transient data like email)...which will add
significantly to the price.  my preference is for RAID-5 with a large
non-volatile write-cache...very fast & very safe.
