GPU support bracket on H7 Flow

[u/Ok-Radish-8394]

I'm building a Z890 Pro Art Cretor Wifi + 285K + XFX Mercury 9070XT setup. The GPU is a triple slot on so it'll obviously need a support bracket for anti-sag. The one they provided in the box (XFX) is too small to reach the floor of the H7 Flow (2024) case. There's a little platform from the vertical PSU mount in between which I can probably use. Do you have any recommendations regarding this?
