This guide is quite good, and it will also be helpful to someone replacing other parts on a Samsung NP300. The WiFi card is buried deep, and many other components are removed along the way. So if you only wanted to swap hard drives or optical drives, this may be the best guide available. Thanks for all the clear photos and descriptions, Ryan Miller!
