There is not much here with the MSI Z77A-GD65 GAMING, but definitely enough to get you started, as well as a couple of neat extras. A full list is below:
1 x User guide
1 x Software manual
1 x I/O shield
4 x SATA 6Gb/s cable
1 x SLI bridge
1 x MSI case badge
1 x Driver disc
4 x V-Check cable
2 x M-Connector
1 x Door hanger
Add-on Acessories
One additional thing I found in my box that will probably not make it into retail packaging is a review guide. I do receive such documentation often, but it usually only consists of a simple list of board features with a description of what they do and what they are good for. Such things are really only useful if I get products before the retail launch as I did with the MSI Z77A-GD65 GAMING board, since similar explanations can be found on the product page of any board maker's website. As you can see, it's printed on premium paper stylized to match the box, so a fair bit of effort went into producing it, which is why I have included a couple images of their review guide. Like the testing certificate, I also tossed it aside. If you look closely at the second image, MSI expects reviewers to use three PCs to properly show all the features. It is no wonder that they also included a door hanger to tell people you are busy...this review guide expects a bit much of the reviewer.
I also found other things of interest in the box: a set of cables to check voltages on the board and a couple pin headers to make attaching all front panel connectors of your chosen enclosure a bit easier.
There was also an MSI-branded SLI bridge and a special, large MSI GAMING SERIES case badge with a fancy dragon motif. I love dragons!
