Accessories and Documentation
Inside the box that was tied to the drive bays you will find a 3.5" to 2.5" plastic adapter tray and two metal, 5.25" to 3.5" adapters. For all of your 3.5" hard drive installations, just take two of the twelve provided slides and stick one in the holes on either side. Simply slide the drives in and make sure the tabs lock into place.
Also included are the motherboard speaker, screw and security loop surrounding four spacers for 200mm fan installation. You get ten zip ties to aid in wire management, and screws for the power supply, risers, screws for the front fans, and screws for the risers and miscellaneous drives to finish off the included hardware.
The instructional fold out has great information, not only for the parts and included hardware, but also offers well detailed instructions on how to use the HAF 912 and all of its included features.
