If you pick up an inexpensive dual core CPU at frys/newegg and a couple gigabit cards you'll be in excellent shape. there's little you can't do with that kinda processing power routing wise (there is an upper limit to the number of vpn clients you could accomidate if you decided to add a vpn server, for example). Get a decent mobo with enough PCI-E ports for your quality, name brand NICs, and as many 1/2GB RAM sticks as you can afford up to what the motherboard supports, and you'll be in excellent shape and on an awsome budget.

I will be pushing 25 - 30 Mbps at this point. This will have a private internal network with "Average" usage behind it. Up until now I have always had a FreeBSD box doing this job with no port forwards (Basically just an internet sharing role). I plan on redoing the box as it has started having slight hardware issues and decided to go Ubuntu/Shorewall since that is what they use at my work (which I took over as IT Manager and admin the box). Now the only networking changes that I am considering doing is moving some public servers to behind it. I have had a FreeBSD email server, Ubuntu Asterisk server, CentOS Web server, and a Windows 2k8 server open to the internet with real world IP addresses. I know, everyone is cringing right about now, but I have kept up with the local security on the boxes and not had a problem. The asterisk box is running showewall on it for it's own protection (I cut out most of the crap out there by black listing Russia and China). Anyway, I have been thinking of moving those boxes to behind the firewall. At that point it will be routing for a half dozen low volume websites and a half dozen email domains.

    It is also worth noting that if you wish to do traffic shaping
    that will
    impact your hardware requirements as well.  It is worth noting that if
    you plan to do traffic shaping or accounting, that will require more
    powerful hardware.

    However, Simon is right.  Without more details it is impossible to
    give
    you anything resembling a sensible answer.
