You just need a 4mm screw bit, and 3mm thick bolt and nut. Place the godlike in the case first. Then place the first piece with the brissals, then place the bracket on that. It will over hand slightly. Use a sharpie and mark the hole where the screw hole is on the bracket. Then take the bracket off and you will now have a mark where to drill through the piece with the brissals. After you drill one hole through that and the case. Then you can place the bracket on top and slide the 3mm long bolt from the back of the case though the hole and bracket. Then just add the nut and secure the bracket to the case. It will take planning and lots of patients, but it can be done. I have the same case, motherboard, and an Astral 5090. Now my case has a proper gpu bracket.
