when I was installing my GTX 1070 I noticed that thier was a hole near the slot bracket (same with my old GTX 770 ACX)
what always make me nervous is when I try to mount the screws is they could slip and fall inside the video card so I used a piece of masking tape as a temporary safeguard
This problem should really be fixed evga needs to add a piece to the side of the card to cover that hole
