when it says that it has 8 internal usb ports, or the like, it is saying that the motherboard has 4 headers, that support 2 usb devices each, for a total of 8 ports. these are whats used to plug in things such as the usb ports that are on your case, a memory card reader, ect ect. when the description says "rear panel prts" it is talking about the back plate of the board, where you can actualy see the usb ports, video out (if supported) and audio outputs. so if it says 8 usb undet this section, it refering to 8 actual ports that you can see. if its under the description that says "internal i/o connectors" it is refering to the usb headers on the motherboard, in which you will plug a usb header from the device that you are anting to use, such as a card reader, or yur cases usb ports. if it says 8 usb under this section, its refering to the 4 usb headers on the motherboard, which mind you, support 2 usb ports each, for a total of 8
