The gpu support is specificaly tailored for the case Corsair 6OOc in combination with Radeon XFX RX6800. It is mounted with four standard fan screws into holes of premouted fans. I used some superglue to hold it together. The shape allows for non-restrictive airflow from the front panel fans, straight into the GPU heatsink. Could be compatible also with different GPUs- not tested.
