Normally, I don’t include a section for the extra accessories that come with a case unless it is truly something unique and different.
The first item could be the plastic brackets for helping to absorb the weight and secure your video card to the system.
In this photo we see Lian Li has included a small organization boxes for any leftover screws. There is also a bracket plate for support for SSI motherboards.
And lastly, there is a adapter to convert a 15-pin USB 3.0 header cable to a standard 9-pin connector to a standard 9-pin USB motherboard header.
