Depends on the size/shape of the fan grill. In most cases, no, not significantly.

The metal grids on the back of most cases will reduce airflow by quite a bit. If it has really large holes its not so restricting but heres a test, take your fan out and feel how much air it is actually pushing. then hold it up to the grid or grill and then see how much its pushing then... I am gonna take a drimmel to the back of my case.

Thanks everyone. My side case fan for the CPU is slotted circles and relatively free flowing, but my rear case grid is only about 50% clear. The dremmil sounds like an excellent cure.

Yes use the wire grills if you can and cut out those swiss cheese grates on the case, they are terrible and make a lot of extra noise.

So what is the best way of taking out those metal grills in my case? I have 2 in the front blocking my 2x80mm front fans causing them to blow very little air, but the metal is pretty tough... ?

Yeah, they increase the fan noise output by about 10db.

Use a Dremel with a carbide cutter or cutoff wheels, then smooth with a drum sander.
