I recently upgraded the GPU in my TOTB-2 workbench gaming computer, going from a Radeon RX 580 GPU to the new Radeon RX 7800 XT GPU from Sapphire. My temporary GPU support bracket (piece of wood trim from our Australian Cypress hardwood floor install a decade ago) needed to be more secure. Well, you know how I like to bend metal bars and such, so yes, I made a GPU support bracket out of 1" aluminum bar. I bent it into shape, drilled a hole in the base, and attached it to my shelving unit so it would be secure. I played a few rounds of World of Tanks - Blitz (everyone knows this is my favorite game right now) and everything is working well. This project took about an hour, with half the time spent trying to figure out a way to drill and then screw in the screw with all that computer stuff in the way. I finally had to pull the video card out a bit so a longer Phillips screwdriver could reach down and turn the screw into the partially drilled screw hole. I used an adjustable wrench to turn the shaft of the Phillips screwdriver a 1/4 turn at a time while I pushed down on it from above.
It pays to have a few vices in life.
Ok, the GPU support bracket is bent and drilled. Ready for installation.

There is that screw that was hard to reach, even with my vast assortment of tools. I was aware of the two spinning fans that I didn't want to obstruct.
