 The connectors used for the module cards are physically (but not electrically) PCI-Express x4 Slots. Those are reasonably cheap and generally available at electronic shops.
-One of the ports is special, it is the port for the busmaster. The busmaster controls the stuff that happens on the bus and is also controlling the bus protocol. The busmaster port has an additional set of pins at the front of the PCIe slot. Thus not more than 1 busmaster can be present on the bus.
