Accessories and Documentation
In that thin white box packed next to the hard drive bays you find quite the assortment of hardware. Part of that is the set of wire ties, the motherboard speaker and a set of foam washers for, I would guess isolating anything you may see the need for, since it isn't addressed in the instruction sheet.
The screws and risers are comprised of the set of four screws at the top left for the power supply, the risers with Phillip's head socket and eight fan screws. The bottom two sets are the left set of 6-32 screws for the motherboard and 3.5" drives. The screws on the right are M5 screws for 2.5" hard drives.
The instructions are multi-lingual and offer really good images and text to describe almost all of the parts and a full build. If you have any questions aside from where to place the four washers, this manual has you covered. In the bottom right corner of the manual is a product inset that shows off all of the other products NZXT offers to complete your build.
