are you still making this bracket? I might be interested in buying one.
I have an RSV-L4500 case that I've currently modded to fit 8 GPUs. I did not use any extra parts except what came with the case. I've oriented the cards to be facing forward, with fan airflow front to back as is intended. I think I'm looking for a more secure and clean solution for my second build though, which is why I'm considering this. my cards kinda just hang there lol but it works
i removed the support beam, and moved it more forward. GPU's are just zip tied here
i removed the center fan wall and moved it back behind the beam.
i replaced all the fans with Noctua NF-F12 iPPC 2000rpm fans, removed the rear 80mm fans completely
even with 8 GPUs, its easy to keep card temps between 65-70C with only 40-60%
makes for a very tight fit with a full size ATX MB, and long-ish PSU, but i got it working. it works better when you have one of those narrow PCB motherboards like the Asrock H97 Anniversary. but i digress.
Even with your bracket facing the GPU's the other way, I would recommend still blowing airflow front to back (but only if you dont have a blower style card, other multi fan units will vent in all directions, not just back), with the center fanwall added back in for more airflow. it's just 4 holes to drill and
