In my experience getting rid of the hot air the components produce turned out to be more efficient than bursting as much fresh air as possible inside the case
Also, the heat rises, so it's wise to have top fans as exhaust
Just my opinion, sorry
Make the ones on top of the case to blow the air out
It's good to have more fans sucking air out of the case than blowing it inside
Less dust gets into the case that way
Also 3 in, 3 out, would be more balanced than 5 in 1 out
Sorry, i have no idea about the case, but I did some research to help you
Someone on reddit said he measured it and says it's 323mm from the back of the case to the edge of front fan.
So that means 323mm with the front intake fans installed
Hope it helps
They are usualy pretty bad quality
Meant only for basic hardware
For something like 2060 it's strongly recommended to use good quality psu
Can you take a picture of it?
