I'm really sorry if this is just an utterly ridiculous noob question, but I'm shopping for a case right now (for my first build) and some cases have 20-pin USB 3.0 connectors to attach directly to your motherboard, and others (e.g.: the Corsair Graphite 600T; http://www.newegg.ca/Product/Product.aspx?Item=N82E1681...) have a USB "passthrough" that looks to me like just your standard male-end USB 3.0.
If I were to buy a case that had such a USB 3.0 passthrough... what am I supposed to do with it? That 600T has me especially confused because the top PCIe knock-out has a hole in it specifically for routing that USB 3.0. passthrough. I'm confused
Thanks! So if I understand correctly, a USB passthrough will use up one of the USB ports on the mobo, so really it just reroutes the 3.0 connection from the back of the case to the front/top. But if I wanted to, I could buy an adapter for the passthrough to a 20-pin connector and hook it up right to the mobo (assuming my mobo has a 20-pin USB 3.0 socket)?
