Question about Lian-Li O11Dynamic XL

Works great
I mounted a 360mm radiator from EK Waterblock on the top and bottom.

Question@Remoerny: how did you configure your fans regarding pull/push? I ask because I have an AIO Silentloop 280 in the top of the LianLi - O11 and run it in push mode. When I was "cleaning" it from time to time, I noticed that the dust that was led out couldn't get out because of the magnetic dust filters.
Question1:
I am now considering whether I should do pull at the top in the future and then install another fan at the back for push to the outside.

Question2:
Bottom and top fans/radiators in pull mode and 1x push at the back to configure the air out.

Is there a "no-go" for question 2 or what would you recommend here? I'm a bit annoyed at the moment and am thinking of just getting something new and then configuring it perfectly (but not yet 110% sure).

About a feedback, thank you in advance.
Ciao
