I was just thinking about this from my multiple monitors thread. I could get another PCI vid card to support a third monitor, but here's my problem: my computer has 3 slots. Two of them are filled (Hauppauge TV Tuner card, and Wireless internet card). My third slot doesn't seem to work (I tried the TV card and wireless internet card in it and got no response). So can I get like external additional card slots or something? I've seen external USB ports so I figured they might make external PCI card slots or some sort of adapter, too.
