The NCASE M1 v6 has a USB-C port on its front panel, but if you've removed the front I/O because your GPU is too big (or you just don't like the look), then you lose one of your motherboard's USB-C ports. This model allows the USB-C port to be attached to one of the two power plug slots on the rear panel instead.
The following extra hardware is required:
The parts are designed so they can be printed without supports. Place the largest side of part flat on the build plate. Some features are 1.5 mm thick, so use 0.1 mm or 0.15 mm layer height for accurate dimensions. I recommend using a higher temperature material such as PETG.
First, use a soldering iron to press the two heat set inserts into the holes in the back of the body part.

Next, remove the cables from the front I/O panel, and slide the clamp part into the notch on the USB-C cable. The flat side of the part should be towards the USB port.

Finally, use the M3 screws to fasten the two pieces together.

To attach it to the case, remove the “NCASE M1” badge from the rear panel, and put the cable in its place using the same screws.
