Review on Enhanced Gaming Performance: EZDIY-FAB New PCI Express 16x Flexible Cable Extension Port Adapters 🎮 with High-Speed PCIE Riser Cable (90 Degrees) - Perfect Fit for FD R6 Case (20cm) by Jack Enhanced

Generally, a card with a 90 degree stand will do the job, but it's an odd design. The screw holes work, but the back end of the riser card is fully secured with a PCI-E lock. The flat cable is shielded but unevenly anchored in a 90 degree arc. In general it works, but the design may need an update. For those who are looking, you can use it with a little modification for Fractal Design Define R6. I've spent some time 3D printing the bracket, which works well, but the rear screw mounting position is still weird and unusable.
