Remember you should NOT expose any unprotected system to the internet, even during installation. It doesn't take long for a machine to be infected.

Personally, I'm using a mini-ITX board with a 600MHz processor (the slowest I could find!), and with just firewall/DHCP on the machine, I struggle to get the processor load above 2%. This is using OpenBSD rather than Linux however. This whole setup will fit happily in less than 128Mbyte of disk space, and really doesn't need much memory to run.

However, I used FWBuilder to build the ruleset for my OpenBSD firewall. I have a requirement for support for multiple IP addresses, and the OpenBSD firewall (pf) is pretty powerful.
