2 plugs From my Case/Chassis wont go into my motherboard?

[Roflcopter66]

This is my second post xD

 

I have recently invested in building a pc, and i have all the parts put in apart from the graphics card (other post)

 

And what seems to be 2 plugs coming from the case?

 

Now i have had about 4/5 other plugs that come from the case and have all been allocated a slot onto the motherboard, names are,

 

Usb,

Power SW

Reset SW

Power LED

Speaker

And HDD led

 

But there are 2 more that don't seem to fit anywhere?

 

Names are:

 

HD audio

And AC'97

 

Do you know what these are and if they should have a spot on the motherboard to fit into???

 

The Motherboard is:

 

dabs.com - Asustek S775 GeForce 680i ATX GLAN (P5N32-E-SLI)

 

The Case is:

 

dabs.com - Akasa Zen-Black Silent Midi ATX Case (AK-ZEN01V3-BK)

 

Thanks alot =]

They are just for the audio - if you are using speakers - you dont need em - one is for the front socket for the headphones and the other for a speaker in the PC for post errors, if I understood correct :)
