Ok here's the deal. I just got a Desktop PC (800 Mhz, 40 GB), im planning on using it for music and back-ups etc....now can i network my two PC's without having to buy a router etc ? I have a DSL modem (one ethernet outlet), the "new" PC has an ethernet PCI card, dial-up modem, USB ports the usual, my "old" PC has an ethernet PCI card, dial-up modem, USB ports the usual, they're pretty much the same....can i network them through the dial-up modems or somehow else, the new PC doesnt have to connected to the internet, i just wanna access files on it from my current PC...

Thanks
