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.
