I need to add a usb card in the back of my dell 435MT. I am trying to figure out if I need a PCI (normal) Or PCI Express. I speak to dell, and they struggle to tell me in english I should just buy a hub, and try to sell me as I am explaining I don't want a hub, and just need to know if I need a PCI or PCI Express. So I disonnected and tried the forum, but it won't let me log in. HOPING somone here will know the answer??? Becuase I have a printer that I need to hook up (because the firewire does not work and Dell was great on helping with that problem too). ANyway, if anyone know, I really appreaciate it. Thank you.
