With a full EK water block cooled ASUS 1080Ti it feels almost mandatory to do a vertical GPU. One thing I learned with Project Zeuligan is that the back of the be quiet! Dark Base Pro 900 is a little to flexible to support a GPU without some sag. Therefor I decided to do a full cover plate as a solution for a vertical GPU bracket holder.
Started with marking out the tooths for the motherboard side and went to work with a hand saw.
First I cut a hole for the GPU. Then I did a grid of 10mm squares for one size of holes. This is also something I feel makes a difference when creating items like this. Specially when you do it by hand. Two different sizes of holes will make it look more unified AND will easier mask any small miss-placement of the holes.
3,2mm holes with the Dremel in the Dremel work station drill press. The way I do it and feel works best for me to counter the flexibility of the Dremel is to first position it correctly and do a very very small mark. Then firmly tap the drill a few times before finishing the holes. With constant pressure the drill tend to move to any side, due to the flexibility in the Dremel mounting and the shaft it self.
I added an other 10mm grid, but 5mm repositioned to get a hole every 5mm. These holes I drilled with a 5mm drill.
Created a side bracket with cut outs for the case rivets and threaded the holes for the thumb screws. I also added two fastening plates for the GPU end holder plate. That will be painted red.
Test mounting, feels sturdy and will hopefully keep the GPU perpendicular to the PSU shroud floor.
The backside clearly shows the tooths of the plate.
Painted and with the GPU holder plate painted in red. Acrylic and paint goes a long way.
