The case front panel is using AC97 conenctor. Board is using HD (the one with no jumpers) Audio connector.

How do I connect those connectors together?

Tried Google, can't really find any help.
 
Usually Front Panel HD Audio Connector also supports AC'97 Audio module, that is, you can use your case front audio ports with the AC'97 pin assignments:
  1. Pin 1 - PORT 1L -MIC (Front panel microphone input signal)
  2. Pin 2 - GND - AUD_GND (Ground)
  3. Pin 3 - PORT 1R - MIC_BIAS (Microphone power)
  4. Pin 4 - PRESENCE# - AUD_GND (usually no connection)
  5. Pin 5 - PORT 2R - FP_OUT_R (Right channel audio signal to front panel)
  6. Pin 6 - SENSE1_RETURN - FP_RETURN_R (Right channel audio signal return from front panel)
  7. Pin 7 - SENSE_SEND - AUD_5V (usually no connection)
  8. Pin 8 - KEY - KEY (No pin)
  9. Pin 9 - PORT 2L - FP_OUT_L (Left channel audio signal to front panel)
  10. Pin 10 - SENSE2_RETURN - FP_RETURN_L (Left channel audio signal return from front panel)
