These don't take a normal/half height bracket to go straight in a pci slot? I need to look up what a chassis backplate is then, and whether I can use that.made for ASUS chassis backplates, you need other cables.
if you take the 4x Oculink Card, Slot 3 is disabled.
i see in the chassis manuals the 90 degree cables.
Plus new cables ... 4x 30 euros. Its getting expensive lol
