The motherboard I am using uses a different connector to the 16 pin front panel connector included with the chassis; it does not look like the 20-pin Front Panel Cable Pinout on the manual; so presumably it can do the same for the 16-pin cable?
You can use CBL-0068 / Front ctrl cable 16 pin split, 24" (no converter head), and it does the same with 20-pin cable except the last 2 pins: pin #20 and pin #19 are not using. Please see attached picture.
