I have the exact same config (P75/32Mb/500HDD). It is powerfull enough to
run Gentoo and acts as a firewall, mail server, SSH server and dns server
for my home network without a glitch. No DMZ really, but it uses a wireless
USB NIC and an Alcatel Speedtouch ADSL modem plugged into a PCI usb adapter.
I even have an old ISA 3com NIC to backup the wireless link (just in case).
I sometimes use the 3 NICs simultaneously for debugging purposes and never
had a problem.

I also use ntpdate via crontab to sync the old drifting clock to a public
time server.

One caveat: too little hdd space and raw power to compile anything. So I
compile on my larger box, and rsync the changes via ssh. Works like a charm!


Hope it helped...
