The card in the bottom slot is just a spdif bracket feeding off the onboard sound. I also purchased a usb3 header to female type A adapter so that I no longer have to run the usb3 front panel connector out the back on my case.
I really wanted to get a 6700k and the D14 cooler but my asrock z77 board was giving me lots of problems so I had to order the final pieces ahead of schedule.
