Inside the box, various accessories were found, however it seems that they weren't as much as those provided with motherboards like the the Z68's big brother, the P8P67 Deluxe. The Input Output Shield is a fairly simple one, which is not padded nor black.
Other accessories include a SLI bridge, driver CD and Asus case badge, Asus Q connectors and also 4 SATA cables.
If you think the last item in the box is just another USB2.0 header, you're so wrong. It is actually a USB3.0 expansion that gives you an extra 2 USB3.0 ports at the back of your case.
