cases with side window = more noise ?

[lukx]

Ok might be stupid question but you guys now better so I will ask.
I'm planning on buying this big case for evga sr-x mobo and I'm thinking to go with window or windowless option.
My main concern is noise... so does window have any effect on it? Or it doesn't matter?
Let's not forget there will be two xeons on board So I really need to take care of sound coming out form this monster.

Just use a transparent aluminum window instead of cast acrylic.

edit: oh sorry, wrong time period.
