Asking because, in my research into cases, a fair number of them it seems, only have a 'grill' at the top, no dust filter.
I'm not planning on OC'ing my system at all, so was just thinking one rear fan (maybe a front one too) and leaving the other fan slots empty.
So I was wondering, if where the two fans go at the top is just covered by a grill, surely when the rear fan is pulling air out of the case there is a chance that the air which replaces the air inside the case comes from above the case? Which would not be desirable.
