I want to buy an Alienware area 51 R3 with one GTX 1080ti.
I have another PC and I can use the current GTX 1080ti from it to add a second GTX to the Alienware.
I can mount the video card by myself (I built my current PC). Would that void the warranty?
As long as there's no mod(s) while adding the second card, it will not void the warranty.
