ASrock Extreme 4 z77 what are PCI short slots

[machv1]

I have a ASRock Extreme mobo, I want to put two gpus in sli config, I have ordered ll of these parts, I have done some reading and it says after you install two gpus in sli you have two pci short slots left over. I wanted to order a sound card and I'm confused whether I will be able to buy a sound card will it fit in these two leftover pci slots, the sound card I want is the Xonar Essence ST . Maybe the Xonar sound card which requires a PCI slot will work.

As I see it, you would be able to use the top and the bottom PCIe x1 slots.

You'll have both PCIeX1 slots available and the legacy PCI slot to choose from. Both are common sound card slots. Personally, I am using the top slot for my similar board layout.
