Layout of the mainboard
The mainboard has 3 full length PCIe 2.0 slots (in red) that supports Quad SLI/SLI or Quad CrossFireX/3Way/CrossFireX. As P67 no longer support PCI lanes, a chip from ASmedia is used to supply PCI from PCIe X1. Behind the PCIe slot is the audio codec. Behind the CPU socket are two GbE from Realtek and USB 3.0 controllers from EtronTech.
At the bottom left hand corner of the board, we can see the Power and Reset switch, next to it is a debug led. At the front is 6 SATA3 connectors and 4 SATA2 connectors. There is another EtronTech chip nearby to support the USB 3.0 front panel. over to the right is 4 DIMM slots supporting up to DDR3-2133 dual channel memory.
At the rear we see PS/2 Keyboard/mouse ports, CLR CMOS, Coaxial and Digital SPDIF, 4 USB 3.0, 1 eSATA3, 1 1394, 2 GBE LAN, 1 FATAL1TY mouse port (red) (on top of 1394 port) and audio ports.
