I currently have 3 front panel connectors all connected together (you can't pull one off without pulling off the others):
Note that there are 9 squares on that, not only 8. There's 1 above the green.
From the top to the bottom, they are: PWR, HDD, DC SW.
I'm assuming that means: power light, hard drive light, power switch.
I want to get a new motherboard, and if possible keep my case. Is there a way to unconnect these connectors? Are there any motherboards out there that will have those 3 connectors lined up the same way as my current motherboard?
