I'm running something similar (sendmail vs. postfix, mimedefang vs.
mailscanner) on much slower machine (but also, with much less users).

Cyrus uses /var/spool/imap for mail storage. So you might want to
change the above to /var/spool/imap.

For the number of users, you'd probably want to consider dual-CPU
system. Also, unless you impose mailbox quotas (trivial to do with
cyrus), you'll run out of disk space relatively fast (for that number of
users). Remember, with IMAP, mail is stored on the server. Disk is
cheap nowdays, get yourself two 250MB drives ($150-200 investment) and
make software RAID-1. You'll get both capacity and redundancy.
