add-on front USB connector

Hi,
I'm looking for a front USB connector that plugs into the motherboard
header.

This item (http://www.directron.com/usbfemaleada.html) has the correct plug,
but it's a rear connector and is not long enough to reach to the front of
the case. Even a rear connector with a long (40cm+) cable would be fine, I
could modify it to fit on the front of the case.

Anyone know of any online stores that stock such an item? I'm in Australia,
so a store here would obviously be preferred.

thanks heaps.
