For your Audio Card my friend stop searching cause its not Compatible, get a new one (better if its USB) for the PCI Network Card do yourself a favor, go to D-Link's site and search if it has Support for Mac or Insanelymac.com and search for someone using them almost 80% sure wont work

Anyways use the one in the MOBO cause its fixed and get a new Sound Card...Hope it helps and please... Stop thinking it might work. Go to OSX86PROJECT.COM and search for the Compatible products over there with Hackintosh
