I remember quite a few discussions on using low power PC's. You think I can find that thread now? Of course not! I remember someone having a link to some "build it yourself" PC's with external power supplies.
What I want to do is make my own Smoothwall firewall PC instead of the old Linksys box. So I'll need at least one PCI slot for a second NIC. With built in NIC, all I need then is a hard drive slot.
Thanks guys...
