A:Answer I am not sure if that was a serious question or not, but by adding a graphics card to the PC, you would be upgrading it.
The PC itself does not have a dedicated graphics card in it, its built on the motherboard, so you would need to add a dedicated graphics card, such as the 1050 to it.
Now i am not sure on the dimensions inside the case, but it looks like 1050s come as small as 145mm, which is half the size of my 1070 gtx, so this case should fit the 1050 nicely.
