If you're using windows (and I'm guessing you are).. you should be fine with a hub, and network cards in each machine. Connect all machines to hub, enable file and print sharing (win98), set up your shares. It should be as easy as that. Now if you want to have internet access across all these computers, then it gets a bit more complicated. Give us more details, what OS, hardware etc do you have? Secondly, there is a networking forum for this sort of thing here at AT, you might want to try there.
