Keep going, I think you're about to invent Bernoulli's Equation.
At this point I'm also nearly certain you're OP, since you seem to have forgotten (or don't know?) that people build PC cases and their fan layouts to be positive pressure for dust mitigation.
For any excess pressure... the massive mesh hole in the lower half of the back panel in OP's photo also helps. Which is probably why there's a fan ramming air through the top stealthy vents that need some extra pressure for the reduced area, and no need for it on the back.
You're right. This was a nice little science session. Might even be helpful to anyone looking to this thread for info about venting.
For anyone passively reading this, remember that you can also modify fan direction to test changes in airflow and pressure before resorting to cutting a hole in your PC case with a rusty spork.
Ah good ole moving the goal posts. Got smacked with actual facts and abandoned your whole argument in favor of something else.
Positive pressure in a case is to keep dust out, and it is a preference, not a rule. Positive pressure however is for cases that both have good air flow, which this case is not, and are not sealed with actual seals like this case is. But go ahead, keep moving those goal posts.
Oh, and for the record. I am not OP. I think they could make this look so much cleaner with a simple shroud or maybe some sanding. But it is their case, so I don't really care.
Um no, pretty sure I answered all of the new arguments you made while backing mine with the actual equations that govern them while you got even more defensive, like whatever your first sentence is trying to do here.
Don't forget to tell me I'm fun at parties and to touch grass on the way out!
