Ok, I have a Lian-li PC-C50B case, it has a SD card reader built into it. It has a 4 pin connector on it but I don't know where or how to hook it up. Can anyone offer any help or suggestions.

It connects to the USB header on your motherboard, look at the installation guide that came with the case to see how to hook it up. You can also find the manual for your case online, that's how i just did it.
