Accessories and Documentation
In the green bag that ships in the hardware box you will find this great assortment of hardware. Six wire management clips, a trio of zip ties and an assortment of screws for the motherboard, drives, and even four longer ones for adding an optional fan.
The 3.5" hard drive trays will also work with any 2.5" drive via the four holes in the floor of each tray. For 3.5" drives, the tabs on the sides lock them in place.
The instruction manual is shipped under the hardware box in the bottom tray. While it holds a lot of information, there were some important aspects I found myself having to work out on my own.
