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.
