Question Will removing the PCI-E brackets at the back of your case cause dust build-up if your case has positive pressure airflow?

[Schytheron]

So basically, I have a Fractal Design Torrent case which is an EXTREMELY positive pressure focused case. I recently got myself a RTX 3070 MSI Gaming Z card which came with a GPU sag bracket, but in order to be able to install the GPU sag bracket, I had to remove almost every single PCI-E bracket at the back of my case (I have no idea if this is intended or just extremely bad design by MSI) which caused my case to have a big gaping hole back there.

Will dust get sucked into my GPU through this gaping hole, clogging my GPU with dust or will the positive pressure airflow completely prevent that from occurring? It should be noted that the back of the Fractal Design Torrent is extremely hollow/transparent even with the PCI-E brackets installed.

Here are some picture for context.

Example of how hollow the PCI-E brackets are normally anyway:

Is it safe to keep it this way?

Positive pressure meaning that air flows are naturally out of the case - correct?

Dust sticks because of electrostatic attraction.

My recommendation: block the openings and monitor dust build up.

In the meantime, can you provide more detail regarding;

"I had to remove almost every single PCI-E bracket at the back of my case (I have no idea if this is intended or just extremely bad design by MSI) which caused my case to have a big gaping hole back there. "

Add photos and explanations.

Something seems astray.

I had to remove them because the stupid GPU sag bracket spans across 4 PCI-E bracket holes but only allows you to screw in 3 of them. In other words, there is no hole in the GPU sag bracket that lines up with the fourth PCI-E bracket hole, forcing you to remove that bracket in order to make it work. And since the screws in the PCI-E brackets need to all be removed at the same time before installing the bracket it becomes a pain in the ass to align and screw in the GPU sag bracket without any of the loose PCI-E brackets moving out of place or tipping over.

So I just said <Mod Edit> and removed all of them.

You can see that there is a forth PCI-E bracket in the middle that has no corresponding hole in the sag bracket.
