The board comes with 3 PCI, 2 PCI-Ex8 (2 green) or 1 PCI-E x16 (yellow) for PCI-e graphics cards, 1 PCI-Ex1 which allows for future expansion cards. The power on board is based on a 3 phase design. If you notice, Jetway's design do away with the SLI/Normal card to switch between SLI or Normal mode. Instead Jetway's design is based on auto sense. When you insert a single card into the yellow slot, it means you will be running it in PCI-E x16. If you insert the two cards into the green PCI-E slots and attach the SLI bridge (not supplied in package), you will be able to run the board in SLI mode. behind the 3rd PCI slot is the Realtek ALC850 audio codec. Further to the right, you can find a Marvell GbE LAN chipset. Further down, you will see the voltage regulator with heatsinks attached onto the MOSFETs for better cooling of the board.

At the bottom of the board, we see 4 DIMM slots supporting up to 4GB of DC-DDR400. There are 2 IDE ports supporting up to 4 IDE devices and 4 SATA ports are also supported by the NF4 chipset. They can be mixed and match to form a NVRAID array. On the left bottom corner we can find the Debug LED. The power on and reset switch are easily accessible for DIY users. This is definitely a better way than to find a thin wire to short circuit the front panel Soft Switch.

The back panel consists of PS/2 Keyboard and Mouse, 2 Com ports + 1 Parallel port SPDIF, 4 USB ports, 1 x GbE port and 8 ch audio ports.
