This full ATX mainboard comes with 3 PCI and 3 full length PCIe x16 slots. Although they are full length slots, they're electrically PCIe x8 for the yellow coloured slots. The white slot is a PCIe x16. As it is based on the 650i chipset, it supports SLI. To run SLI, just slot in the two cards in the yellow slots. There is another PCIe x1 slot next to the yellow slot.  Behind the PCI / PCIe slot are the audio codec, GbE and I/O controller chipsets. A 4 pin SLI power connector is sighted next to the PCIe x1. To it's right is the 24 pin power connector.

At the bottom corner of the board, we can see the BIOS, front panel 1394 (red) and USB connector (blue). Below the CMOS battery is 4 SATAII ports managed by the NF 430 south bridge. the VIA VT6308S 1394 controller sits right below the 3 PCI slot.

Moving towards the centre of the board is the North bridge NF 650i that supports the FSB1600 CPU. There are 4 DIM slots support 4 DIMMs of up to a total of 8GB of DDR2-800.
