PCI-Express has nothing to do with PCI, they're different slots. I'm selling hardware, and as I said before, current motherboards does not have 5 PCI slots. The last boards with 5 PCI slots were these: Asus P5P800, with AGP port, socket 775 on board 10/100 LAN, DDR 1 support. I have couple of these on stock, we're using them for servers where we need a lot of Ethernet ports. You will not find on any PCI-Express board 5 PCI ports, unless it is a server dedicated, expensive board.
