OpenBSD is the best way I know of to do this, hands down. It'll save you more money and headaches than you can imagine. The only thing FreeBSD has on it for this application (i.e. domUs, virtualbox, zfs not applicable) is easier Sguil http://sguil.sourceforge.net/ installation, but OpenBSD has a tighter security profile, easier maintenance, and narrower attack profile than any other OS or distro.
