Accessories and Documentation
Remember that white box with the Ikonik label on it stashed in the hard drive rack? Inside that you get a couple thumbscrews to replace two regular screws in the door panels, a bag full of risers and motherboard screws, a pair of both wire management stick-on clips and tie straps, an Ikonik cleaning cloth and a set of power supply mounting screws.
As I mentioned, to install a 3.5" hard drive you simply set the rubber nubs into the screw holes of the device. Holding them on the side while sliding the drive in, you eventually hear a click as the drive locks into place. The top of the slides are sort of spring loaded to keep them in position on the rails, while the rubber bits that hold the drive further isolate the vibrations.
With the drive locked in place, simply slide the assembly back in the chassis and replace the four thumbscrews to secure the rack in place.
