My 2nd build included ASUS P8Z77-M. I was aware of the uATX setup but I wasn't aware of the poor on board audio. A need has also arisen for high quality sound. So I have looked around and settled on the Xonar D2X but the current placement if the graphics card prevents access to the PCI Express slot but I can move it down into the second slot.
All I need to really have clarified is does the Xonar D2X need extra space beneath it or can it be placed directly next to another card?
