Network connectivity is provided by two Marvell chips, but why the second is only a PCI chip is beyond our imagination, as it will ruin the perfomance if you use gigabit. A VIA VT6308P provides two ports of FireWire 400. This board contains no onboard audio, because ASUS decided to add an external audio card called "Supreme FX II," which should increase sound quality over onboard solution. As usual, an Analog Devices AD1988B is used.
Another plus are the angled SATA and PATA connectors.
