In my opinion, the last thing you want to do is to make Motherboard mods to a laptop. Norway is right about that; and there are no GOOD gaming laptops on the market today, and haven't been for 15 yrs. If you build a Custom-rig with a standard computer case in mid-tower or full-tower size configuration, this is your only option for no overheating airflow design. Anything you plug into the laptop Mobo will likely draw more power than the laptop was designed for, and either short it out or burn it to a crisp. I've seen folks do this, so if you are not particularly fond of that laptop and don't mind replacing it--then do monkey around with adding devices to the Mobo. (though it might be easier to find a really high building or bridge and just toss it off the edge into space). :\
