Two DIMM slots coded in Orange sit right below the CPU socket. Next to the DIMMs we find the 24 pin power connector.

On the bottom left corner are the front panel connectors (not color coded unfortunately), two USB 2.0 headers, 4 SATA II ports and covered by the ECS sticker a ICH7 Southbridge chip.

There are 2 PCI slots, 1 PCIe 1x and  1 PCIe x16. Towards the centre we can see a clock generator. Notice the passive heatink ? That would be your North Bridge (G31) silicon underneath it. To your right we can see the FDD and IDE connectors.
