That's what I thought but the following was the reply to my query when I first asked the company who were buiding my PC.
This motherboard comes with wireless LAN onboard and therefore if you order a wireless network card you will receive one spare card that can be added to another computer.
I still wasn't sure if that meant yes or no! however they did install a card in my PC but when I installed all the network/ card drivers the PC froze so I had to start in Safe Mode & have disabled them all at the moment.
