Ok so I opened up my PC because I was planning on changing PC cases. I see my wifi adapter has a white cable and a black cable connected to it. The black cable goes to the back of the computer and it doesn't seem to be connected to any port. It just seems to be connected to some metal. The white cable just goes to the front of the case. I can't see where. How do I take these out so I can move it on my other case?
