Start with a 4 port PCI ethercard

Expand a PCIex1 slot into several PCI slots, claiming 13 PCI slots possible. I haven't tried to assure this is the max possible.

10 PCI slots and a PCIEx16 makes(?) 14 slots

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? Probably.
