Accessories and Documentation
In that black box of hardware found in the HDD bays you get this as part of what is included. You are given an adapter for the 5.25" drives for a card reader, solid plugs to replace the water cooling grommets and an 8-pin EPS extension cable.
You are also given five tie straps, four thumbscrews and a set of standoffs on the left. In the middle are four fan screws, bay adapter screws, PSU screws and HDD screws. On the right you are given screws for mounting SSDs in the HDD trays and the motherboard screws.
This is the 5.25" to 3.5" adapter that Nanoxia sends in the lowest of the ODD bays. The large holes on the outside allow you to pass the screwdriver through to mount the device, then with either the tool-free clips or screws to secure the adapter into the bays.
To mount the 3.5" drives you need the screws with the threads cut at the end of a blank stud. This will allow the blank part to ride in the rubber grommets and also make sure you don't over tighten them. The four small holes drilled into the steel are what you would use for 2.5" drive mounting.
This full set of instructions with color photography to help you along has got to be the most detailed set of instructions to come with any case that I can recall.
The manual starts with an introduction, gives the specifications, offers an easy to follow accessories guide, goes into the features, and even explains about the noise absorbing measures taken in the DS1.
Now the first half of the thick manual is in German, but in the English section you can see that they cover every little detail about how the DS1 works. Great images always help, but the long detailed text will answer any questions that the images may bring.
They even go as far as to show how all of the options work, even explaining a bit about the fan control wiring, optional fan placement, and even how to work the I/O panel if pressing on the raised marker on the top of it doesn't come to you.
