PCI or PCI express?

How can I tell which slots I have?

Answer

A PCI express slot is much smaller about an inch or so long. The PCI connector is about 5 inches in length and commonly white in color.

If you'd like to see a picture of the connectors, they can be found at http://www.build-my-home-computer.com/what-is-a-motherboard.html. This page will help describe the different connectors on the motherboard.

For more information about the connections found on the back of the computer, or the connections that attach to the computer you can see http://www.build-my-home-computer.com/computer-tower-case.html.
