That should be enough of a system for your stated needs. :-)
Fifty heavy-duty users with IMAP/SSL connections, large INBOX and other
often-used folders, and aggressive clients which open multiple
simultaneous connections might use up lots of CPU at times though.

On my home system, a DELL PE2650 with PERC 3/Di SCSI RAID controller,
/var has 16384 block size, 2048 frag size. With FFS it's a compromise
between the size of the filesystem and the size of the average file.
BTW, you can get a similar machine for $600 or less on eBay these days.
