may be ghetto, but for my oldest card, a r9 280 dual-x sapphire, it had no back plate and was very heavy and sagged, So I got a piece of insulated cabling and attached it through the GPU screw holes, there should be one on each corner and attached the other end to the top of the case, to tighten it i used a stick/pole like you would with a turnicate and slowly turned it till my card was lifted.
