I'm using the motherboard from a Dell Inspiron 3847 for this build but I can't figure out the front IO and I can't find instructions for this motherboard anywhere. In the original case the front panel IO is handled by a single cable. Is what I'm trying to do hopeless? Surely there's a way to connect this to my new case.

Bunch of good results there. First result on the images page has people discussing this exact problem: https://forums.tomshardware.com/threads/dell-inspiron-3847-where-does-the-power-sw-reset-sw-hdd-led-power-led-and-go-on-the-motherboard.2876355/
