You will need a broadband router, some cat5e cable with RJ45 connecters if you're going ethernet, thicknet co-ax with BNC connecters if you're going down the shoddy 2meg route or long USB cables if you decide on an USB lan. The alternative is to dial up or connect using a workstation or server pc, then share the internet connection either using the built in connection sharing provided by windows (right click the dial up --> properties then the sharing tab) or use a program like Sygate which sets it all up for you too. you then need to point the subordinate PCs networking properties to make sure they're on the same subnet, and have the IP address of the router or web-serving workstation as default gateway and primary DNS server.
