    So I'm trying to connect the case cable to the motherboard but pins have different names.

    Motherboard pins:

    PIN 1: PORT1L
    PIN 2: GND (ground)
    PIN 3: PORT1R
    PIN 4: PRESENSE#
    PIN 5: PORT2R
    PIN 6: SENSE1_RETURN
    PIN 7: SEBSE_SEND
    PIN 8: empty
    PIN 9: PORT2L
    PIN 10: SENSE2_RETURN

    The cables are:

    SPK OUT L
    SPK OUT R
    MIC BIAS
    RETURN R
    RETURN L
    GROUND
    MIC IN

    I spent ages sorting out my case, unfortuatly most cases and m/b are incompatible with each other, which is why the front panel is often left unwired even on shop sold machines.

    I might be able to help you out but to give you a definate answer I will need name of case and m/b (with website address so I can see them).
    Photocopys or online manual of the relivent pages of the instruction book (diagrams & instructions if avalible).

    Just by looking at what you have written I wouldn't like to give you a 100% answer although it loooks to me like:

    port_L and R -> spk out L and R
    Mic bias -> ??? sometimes GND, possibly presence
    Return L, and R -> GND
    Ground -> GND - pretty sure about this one :)
    Mic in -> ???

    Although I wouldn't do any of that without me having a look at the stuff I requested.

    On the other side, generally speakers etc are low voltage so you can do these by trial and error without concern over whether your stuff will break or not.
    One of my friends did it this way and nothing went wrong.

    On a side note a different friend managed to get a RAM stick in an AGP graphics card slot (What the **** they are different shapes), this did cause damage to the system.

    I take it power LED, power buttons, HDD activity LED, reset button have already been wired in so none of those m/b pins could be to do with that.

    Thanks but another guy told me the answer, it was another configuration for another type of audio, so what I wrote before was for digital audio and seems my speakers don't work with digital audio, so I've connected it for analog audio.

    And I loled here:

    Yeah... I have wired up multiple cases in the past, and have only gotten one case / Mobo that was compatible when it came to front audio.

    The problem is that while case form factors have essentially one standard for each size of the mobo, Front Panel audio pins do not have a unified Standard.

    There are multiple "major" front panel audio standards, and each one is only partially compatible, or completely incompatible with the other.

    Sorry, but in your case its looking like the case / mobo are not compatible. You can play around a bit with different wiring but I dont have much faith in that working...
