Hello, I can't find screws in my case so i can't remove the gpu. My case is Xigmatek asgard 382.

it looks to me like the black piece with what look like a tuning fork coutouts across the top of the cards is a retention bracket. the black tab at the end/top may be a release, the documentation at xigmatek is non-existant. going by the picture and my experience but that bracket with the cutouts needs to slide out and/or away and let the cards lift.
