I am building a new PC with a Corsair Graphite 600TM Case. I have an ASUS P8Z68 DELUXE GEN3 motherboard which comes with a USB 3 front box. I am not sure how to fit the front box to the case? It is much narrower than an optical drive and I don't know if there is an aptaptor or someing that I am supposed to use. Can someone help me please?
