Modding 801 be quiet

[Drabat]

Hello,
In order to have a better airflow I would like to know if in your opinion it was useful to sacrifice the front and the top of this case to do something like this:

Do you think i should change some fan ?

And it's better to get more airflow on top , on front or both ?

 

Thank for the help
