Cheers for the advice man, so I've managed to do a makeshift fix for the moment. I've grabbed a couple of the rubber feet from my NAS, just the back two as the front two keep my fan off the floor. Combined with an old placemat Han bought me, made of chalk and an old PCB seem to have done the trick. I've checked the fan clearence on the card against them as well and there's plenty of room as long as they don't slip. I'll look into gluing them down soon as well to make sure they don't go anywhere.
Also, cheers @Venom mate.
@Prio Yea, as I'd said I've read a little and it seems that cards, especially of this size do bend quite a bit but I was still a little unhappy and concerned with how much in all honesty. I've also had a quick check of similar braces and am seriously considering grabbing one. Cheers again mate.
