The ranger motherboard i would recommend to anyone. Would you be just gaming with the pc or would you be rendering or other things? as the intel i5 4690k is a amazing processor for gaming and the i7 4490K is better for the rendering side and gaming ofc.
Maybe with proof of purchase or contract you could take it to the apple store and explain what happened and show that you are the proper owner and they might be able to sort it out for you buddy .
