So I just got finished putting together the new build and everything works, USB, headphone etc (which is a miracle considering I've never had to do those front pin connectors before). The system ON led works fine, but I've noticed there is no flashing hdd light (Fractal R5) I suspect maybe the + and - are backwards on the motherboard. I may at some point go back and fix that but its hard to get to when the system is fully together. Will that damage anything to just let it run sans HDD flashing light if the terminals are backwards? Or not at all?
