You've just described my setup almost exactly. I have a net4801 running
FreeBSD 6-stable that acts as my home mail server (postfix for outgoing,
and fetchmail, procmail, spamassassin and dovecot for incoming), and PBX
(Asterisk). It's connected via a WL500GP router (running OpenWRT), to my
cable modem and powered from an APC UPS. The only problem I have is the
grunt that's needed to run spamassassin. I palm that off to another
FreeBSD box using spamc/spamd if that box is running. If it's not
running, the net4801 does it (slowly) itself. The net4801 has a 4GB CF
card for the operating system, and a 40GB hard drive for the stuff that
changes (mail etc.).
