"With the popularity and affordability of broadband Internet connection, most PC users today has a network card for their broadband connection. Even if you don't have broadband, you'll still probably have a network card for your home network. And these LEDs are just screaming to be modified! Most NICs have built-in LEDs to tell you if you're on a full-duplex mode, or if you're connected at 10mbps or 100mbps. Some even have blinking ones to tell you when you're transmitting or receiving data over the Net or network. The problem here is that these LEDs are situated at the back of your PC and I don't think anyone would want to go back there just to see your network activity or status right? That's where this mod comes in! I'll be showing you how you can mod those LEDs and move them to the front of your case."
