OS X El Capitan on Core 2 Quad (Kentsfield)

I managed to re-hackintosh my very first hackintosh PC (from 2008 Chameleon and Mac OS X Leopard era) with OpenCore (legacy boot). I wanted to test my skills with OC with an old rig, just for fun! I couldn't get Audio to work with AppleALC, I tried all compatible layout-ids and HPET Fix. As this is only for fun I used VoodooHDA to get at least an audio output.

Below you will find my specs and details.
