Obsidian Series® 800D and 700D full-tower case owners can now upgrade their front USB 2.0 panel to a USB 3.0 with the Obsidian Series 800D/700D Front Panel USB 3.0 Upgrade Kit. Swapping in the kit requires only a #2 Phillips or cross head screwdriver, and a few minutes of your time.
Begin by removing both the case's front and right side panels on your Obsidian Series. Also, it is helpful to remove any optical drives you have in the upper 5.25” bays before beginning. Also, make sure to unplug all your front panel connections from the motherboard.
Remove the 2 screws from your existing USB panel, shown below circled in red. Once you have removed the screws, pull the panel out of the case and pull the cables thru the grommet.
Insert the new panel wiring into the same hole, and route them out the side of the case grommet in the direction of the red arrows.
Once the cables are through the grommet, pull the cables through and put your new USB 3.0 panel into the mount.
Replace the 2 screws, and route your cables through the case as needed. Once you install the new front panel, your case is now upgraded to USB 3.0 and ready to use!
