I have done a self build and have the HAF 922 case and an ASUS P8 Z68 V-PRO motherboard at present. I have all the other parts of the front panel connected and are working fine. However, The USB 3.0 Header is blanked in the wrong place on the wire from the front panel that goes into the Motherboard. I cannot seem to find one to buy from anywhere. Does anyone know where I can get one of these if so provide a link to a supplier that supplies the UK.
I know this is an old post, but after searching for this issue myself concerning the P8Z68V-LX, it appears this may be commonplace - My USB 3.0 header is missing as well. I visited the place I bought it from (Microcenter) and they handed me a P8Z77V-LX, no money involved - and I got to keep the old board.
