I think I am very wrong because I'm amateur computer builder. Anyways, I have an old Dell Motherboard and I just bought a new case for it. However, for some of the case's front panel connectors, I can't find where they go on the motherboard.

Here is a link I found of the picture of my motherboard.

I can't find the pins for HDD Led (it has 2 holes), Reset SW (it has 2 holes), power led + and power led - (each have 1 hole), Power SW (it has 2 holes).

Also I have 2 question, I plugged HD audio in to the audio connector, but there is AC 97 too. How do I know which one is right? Also, is it normal if there are 2 front panel usb ports but I only have to plug one front panel connector in for the USB port ?

My case is Rosewill FBM-02

AC'97 is for old motherboards and old cases (2006 and older). You have a 2010 motherboard and newer case, so you would not need the AC'97 wires. Just use the HD audio wiring.

It is common to have multiple USB internal headers. Just use the one you need.
