Accessories and Documentation
The manual for the Carbide 500R is labeled a quick start guide, and that's all it really is. Inside are some exploded diagrams to help show how the components are arranged inside the chassis, and what you might want to look for as far as removing the dust filter, much like the way the back of the box displayed its information. On the back you get a full parts list for all the included hardware that should come with your chassis purchase. If you are lacking anything, or possibly there is damage, that is what the red paper is for. Corsair wants you to deal with them directly and not go back to the point of purchase for issues.
Inside of that white box found in the bottom hard drive tray include all of these goodies. At the top you can see three wire tie straps, two adhesive wire management clips, and a USB 3.0 to USB 2.0 adapter if your motherboard doesn't have a native 20-pin USB 3.0 connection. In the bags lined up at the bottom you get a few extra risers, the motherboard screws, fan screws that go in from the outside of the fans, four PSU screws, and handful of screws for mounting 2.5" drives to the plastic hard drive trays.
The plastic trays for the six hard drive slots will accept a 3.5" drive simply by flexing the tray around the drive and being sure the pins line up in the holes of the drive. For a 2.5" drive, you need to remove the pins from the side of the tray, then using screws you mount the drive to the tray. I know the 2.5" drive is installed backwards; it is just for display purposes.
