Question about Cooler Master Vertical graphics card holder set V3

Cooler Master's V3 vertical graphics card support kit is compatible with standard ATX and m-ATX cases, which includes most mid-sized cases. The Lian Li O11 Compact is an m-ATX case, so this kit should be compatible with that model, as it simply requires 4 PCI slots for installation and offers great adjustment flexibility to suit different m-ATX and ATX cases.
