How To Connect an Interal USB port with Front Panel port

Hia

I have a Asus P5Q3 DELUXE/WIFI-AP Motherboard and I want to able to connect a usb 3.0 card so that I cant have more ports. I have decieded to buy this:

StarTech 4 Port USB 3.0 (900mA per port) PCI Express Card (PEXUSB3S4) [PEXUSB3S4]

I really wanted to have an internal USB port because before I tried to connect my front panel USB to the Motherboard internal option but the cable that came with the motherboard wasn't long enough, so i got rid of the front panel ports and used my back ones.

Now I really want to able to use the front panel ports again but I'm a little confused to how would I connect the internal part of USB card with my front panel, seeing as I don't have my front usb ports any more I would have to buy one of those somehow, does anyone know where I can get an long internal cable and a front panel usb ports? That would be compatible with the StarTech ports I am buying?
