Case too big for GPU anti-sag brace, suggestions?

[Zikar]

So, got everything set up but there's too much space below my card for me to put the anti-sag brace in to protect my GPU. I'm wondering what options there are. I could put a box in there and not have a lower fan there to give it some more height, but I'm wondering if there's other options that would look a bit more professional, like a shelf.

Thanks in advance!

As you can see, there's lots of empty space under the motherboard.

Thanks for the suggestions. I'm not super into having to put things into the mobo since I'd probably have to have to take out the GPU and Parsley mentioned, it does have "Steel Armour" and stuff on the PCI slot.

Freddie64's suggestion seems like the best for me, thanks everyone!
