Networking a small farm

Iv got 2 Intel Pentium 4 systems laying around with linux that i want to fold with. Yet i have no room on  my router to hook them up to the internet.

Any ideas?

Can you afford another switch / router?

You can "piggyback" the second switch / router to an ethernet port on the first, and get a couple of extra ports that way.

I'm almost sure I'm missing another, more obvious, solution.

You could put wireless cards in the two old PCs but I like Aegis' solution.

Iv got the budget of ZERO dollars.
But just incase i come across one cheap and buy it let me clarify.

You mean hook the two computers into a router, then take the router and plug into my main router?

Yes.

I was thinking of a little four port switch.  I've seen them for $25 or $30 US.

If he wants it to have a reasonably fast connection but all it needs are extra ports, and a switch will give that to him, but he has no budget so I would recommend talking to anyone you know and seeing if they have an old router lying around that they will give you (If they are willing to give it away for free then it probably is not not the best but it's FREEEEEEEE). Maby a small business. Don't misunderstand me though if you can get a switch it will probably be much easier to set up but I dout anyone has an extra switch lying around.

Best, cheapest, and easiest solution as mentioned above would be a switch. Did a quick search on newegg and below is the cheapest switch ($9.99) would give you an additional four ports to your network. Of course you'd need to pay shipping on that so going to a local hardware store may be even cheaper.
