Start with a 4 port PCI ethercard http://www.cyberresearch.com/store/industrial-computers-rugged-pcs/industrial-computer-accessories-pc-peripherals/bus-adapters-expansion-chassis/bus-adapters-expansion-chassis-pci/PRO_3212_8873.2.htm Expand a PCIex1 slot into several PCI slots, claiming 13 PCI slots possible. I haven't tried to assure this is the max possible. http://www.cyberresearch.com/store/industrial-computers-rugged-pcs/industrial-computer-accessories-pc-peripherals/bus-adapters-expansion-chassis/bus-adapters-expansion-chassis-pci/PRO_3212_8873.2.htm 10 PCI slots and a PCIEx16 makes(?) 14 slots http://www.cyberresearch.com/store/industrial-computers-rugged-pcs/industrial-computer-accessories-pc-peripherals/bus-adapters-expansion-chassis/bus-adapters-expansion-chassis-pci/PRO_3212_8873.2.htm so 13 or 14 X 4 makes 52 or 56 etherchips on one system with COTS. 7 PCIeX16 slots (http://www.evga.com/articles/00501/) @PCIE->4PCI = 28 PCI slots; @x4 chips/slot is 112 (+2 on the mobo) is 1114 interfaces. Useful? Not my call. Silly enough that somebody will try?
