Bitfenix Prodigy M usb help

Solution
Maybe something like this on the front:

For the back of the case:
www.newegg.com/Product/Product.aspx?Item=N82E16815166026

You need a open PCI-E slot on the motherboard and a molex power lead from your power supply.

Assuming you mean the ports by the power switch, then I don't believe that you can install more, unless you go for a usb hub which you can plug into one of your motherboards usb ports (http://www.overclockers.co.uk/showproduct.php?prodid=CB-112-AK)
Also can you not use the usb ports on the back of your motherboard?
