Actually id also like to see an article on how to do louvres in the case, like u can get on some of the more decent cases.
I tried to do it in the past by cutting c shapes in the case with a dremel and then bending the pieces with pliers, but as u can imagine it just looked REALLY bad.
But the good thing about the louvres is they can be a bit quieter than just an open blowhole (as u can direct the airflow and noise away from u), and they look awesome if done well.
Imagine a case with the top having big shark gill look on top for airflow instead of cheesy finger guards
