Low air flow due to case?

I was thinking of doing some mods to my computer case. The thing is that i have 5 fans (front, side, top and 2 in the back, ALL same type of fans). The front and side fans have good air flow but the others do not.

I think this is due to that, for example, the back fans are "blocked" by the back panel of my case. In other words, the side fan has a big hole with a gril but where the back fans are there are just littles holes (many of them) and there is probably just 50% of a hole there.
--------------------------
Question:
Would it be ok to saw out a hole, out of the case, where the other 2 back fanes and top fan are?

Fore better understanding see the following link :) 3 pictures of what I´m trying to say here.

Cut the rear grills out with tin snips or wire cutters. Have that side fan blow INTO your case rather than out.

Don't saw out the holes as this will create metal shavings (bad news).

That'll work...my case had even smaller and fewer holes. Wouldn't even let dust out and very loud. I used a nibbler to cut a nice big round hole out.

Just take everything out before you start making your holes like you want them i have done the same thing.

another tip is 2 have the fans at the top blowing out as hot air rises so will get rig of more heat same with the back ont if it is directly below psu have side and frount ones blowiong in but always have one more blowing in than out and dont have a fan directly abouve cpu and its facn cos it will disrupt airflow also make sure all vents which hve a fan are sniped open but put a grill on the frount so stop u cuttin your legs off when they next 2 case like i do cos i dont have money 4 grils so its just bluetacked onto my hdd with sige panle off
lol gud luck

To iterate the obvious, break and smooth any sharp edges and put a grille on all open exterior fans.

How about just enlarging the perforations with a drill?

My post listed above describes a way of removing the grills without removing parts (motherboard, psu, hd,pci cards, etc.) Removing everything is tedious and not worth the trouble.

As long as you put something beneath the work area to catch metal chunks(if that happens), you shouldn't have to remove any parts. This is how i removed the grills from my case. Of course, cutting the grills out will result in VERY sharp edges. You wouldn't want to clean these edges up with anything, as this would create a whole bunch of meatal shavings (dust). I decided to use electrical tape to soften the edges up. Next, i placed an 80mm fan grill to protect the fan blades on the outside of the case. Everything works perfectly. Way more airflow, reduced system temp, and no chance of cutting my hands. Just remember to be careful when cutting, don't let any metal pieces fall onto the motherboard.

Of course tape or something like it is fine to cover a sharp edge...too many years of insuring my finished products were finished.

Thanks to all. Many replies :) All good :)

I´m going to take my mobo out anyway. I´m going to be installing the SLK-947U heatsink. Becouse it weighs so much i´m going to but the mounting throught the mobo. Just in case :)

Thanks again.

Thats the best and safest way, so you dont get any metal filings on anything and it is easier to clean up, better safe then sorry.
