Accessories and Documentation
In the bag that was tied to the optical bays you will locate all the included hardware. A set of four wire ties tops the image. This is followed by what I assume are fan mounting pins (the instructions don't show them), an expansion slot cover, and a security loop for the door of the chassis with the accompanying screw. The bottom row consists of a motherboard speaker, seven risers (nine would have been nice), six larger thread screws for the power supply, and twenty smaller screws for mounting the motherboard and drives.
When installing a 3.5" drive, you need to pull the tray s out fully and remove the red slides on the side. Once the drive is in the tray, you can reinstall the red slides and they lock the drive into place. You are now ready to slide it back in the chassis. To place in a 2.5" drive, simply turn this tray over and use the supplied screws to mount the drive directly to the floor of the tray.
As far as reading materials go, Sentey ships a product catalog, the instruction booklet, and a card pertaining to the one year warranty. The instructions are very simply written and do leave a bit to be desired. For instance, telling me for sure what to use the plastic push pins for. Other than that they do offer some nice renderings of an exploded view of the Optimus along with smaller illustrations pertaining to each group of text.
