What did you end up doing to get the GPU shroud to fit?
Sorry, completely forgot about updating with that info.
I cut it down to being roughly flush with the end of the pcb, notched it by about 5mm to clear the upper support for the front panel, and drilled a small hole in the shroud to clear the front panel mounting screw.
No pci bracket
It also has a specific order to install it by:
remove shroud
Remove pci bracket
Install gpu GPU pcb and heatsink into case
Install shroud, angling it in front of case to rear
Screw shroud to gpu
Edit: more pics
It's changed a tiny amount since I took these but it's roughly the same.
