Hi guys. I'm waiting for my new AsRock x99 Extreme4 and read it doesn't have built-in bluetooth or wifi. I'm not a computer expert, so would you please tell me how can I have wifi with my new mono? do I need to buy a wifi device? must be external (via USB) or is it something I can connect inside my mobo? Wich one do you think is the better one? (Brand and model) Thanks
