Goodevening to all people here, hi, I'm new here!

I've just bought my new motherboard the ASROCK 970 Extreme3 R2.0 and I'm just looking for some nice good cases for my upcoming pc.
And I came across the Zalman Z11 plus.
And now I just saw that it uses USB 3.0 ports for the USB 3.0 ports on the case if you know what I mean. ( I'm Dutch here, so I try my best. )
Now I don't really fancy the idea of putting them in the back of the motherboard, so I want them internal.

But the only USB to internal uses a 20 pin connector, which my motherboard doesn't have.
It only has 2 splitted 9 pin for USB 3.0, if I'm correctly.

So I can't find any connectors who only need 9 pins, the possibilities I can find is either buying a PCI card with a 20 pin connector, or a 20 pin connector to 4 pin USB 2.0.
But I'm not sure if the speed will decrease when I put it on a 2.0.

So my question is to all you experienced pc builders, are there any 9 pin USB 3.0 'hubs' , or do I need to buy an pci card for this.

Thank you so much,
Patrick
