1) the noie will be reduced greatly when case is closed
2) with noise dampening junk, case will quiet it more
3)(the conclusion!!!) i need case dampeninng stuff

pretty straight forward to me..
and ways, i got 2 Q's
1) can i cut holes in the foam? right now i got a 120mm blowhole on the side, and a rectangular hole on the bottom(airflow) so i would want some stuff i can cut into
2) is there anything at a smallish hardware store that would work? i dont like ordereing things like this online, because they are such small purchases, andi can just bike to the store.... but it isnt a home depot or anything..just a smallish hw store(im in a small town)
now, assuming i couldnt get anything local,
a) what should i get? keep it cheapish!
