Accessories and Documentation
Inside of the hardware box found tied to the expansion slots you will find these eight slides that will allow you to use the four bay 2.5" drive rack located on the bottom level. You also get 12 wire ties to keep the wiring managed well inside.
Along with what we just saw, you get this to finish off what is found in the box. There are stand-offs and the socket to tighten them, fan screws, long hex head screws that I didn't use, SSD screws for the X-Dock trays, motherboard screws, and the PSU screws.
There wasn't any paperwork, but I contribute that to the rush my sample was in to arrive ahead of the NDA. I almost forgot you also get the motherboard post beep speaker to help diagnose post issues.
I removed the motherboard tray in preparation for the build so I figured I would show it off. The edges are folded to give it strength as well as the indent around the SPU cooler access hole. This will simply slide back into the chassis under the rear I/O and expansion slots that stay in the chassis.
On the left I wanted to show the tab lock system CM offers with the 3.5" drive mounting. Releasing the tab allows the tray to expand, slide the drive in, then squeeze the tray together and lock the drive into place. As for the SSD mounting on the right, you do have to remove a pin and grommet from the side, but then you just use four screws through the bottom to mount it.
