Ok... You can either...
1.) Just jig/dremel it out, and then file/sand it with either a file/rasp/sandpaper until it's nice and smooth. 2.) For fans, get a hole saw, perfect cut every time. They make them up and past 120mm. 3.) Use a guide for a dremel, like thier mini router attachment. Then setup a wood plank to run the dremel against, this will give you a near perfect cut. I'm sure there are other ways, but those are the ones I know of.

There is one more, its a metal punch you use with a ratchet. They are big steel Die's you place one on eather side, with a hole in the center for a bolt. with a big ratchet, you tighten them together. One side is a sharp round blade the other is just a base. as you crank them together one side punches though the case side making a perfect, no bur, hole.
they are expensive, like 100$ die's. they are made for punching holes in sheet metal.

another way
a tool called a fly cutter, basically its a lathe tool thats mounted on a bar. the bar is adjustable its used like a drill bit, but in a very heavy drill press or better yet in a vertical milling machine. the lathe tool scribes a circle and cuts its way thru the work piece making a very precise hole. The tool Joe described is called a knock out punch. Yes there quite expensive and there manufactured by Greenlee. Standard sizes only go up to 2 1/2", I just bought a set and it was $120. I use them all the time in my work. There used by electricians to make the holes for conduit.
Hole saws work, but unless you use a drill press its hard to keep them from wobbling and cutting an imperfect hole. Even a drill press sometimes is not good enough to keep the hole saw from wobbling. When the sawblade just starts to break thru the work piece its got a high chance of jamming, make damm sure the work is really clamped down tight, else your going to have a big piece of sheet metal whipping around like a giant knife blade. This is not good even if you have fully paid medical insurance. Grep

all of the big stores use laser cutters, or something similar.
For our purposes, it doesn't matter too much, as you will be using plastic molding around the edge of the window, which will cover up anything out to a couple of mm. |

yeah I know, I think without the molding looks better too, but with the molding is a bit easier

I too am of the anti-molding crowd.
I think web masta pretty much spelled it out for you. Here is my current setup for holes and windows. ------------------------------------------------------------------------------------ Used Dewalt (corded) drill from a used tool store $20 Bi-Metal 114mm hole saw from major hardware store $24 Bi-Metal 80mm hole saw from major hardware store $8 New, low end "Skill" brand Jig saw and 6 fine tooth blades $40 I cut pretty damn straight windows (no molding) by hand, but I have years of experience cutting things other then my fingers. For a couple of bux more you can get two "C" clamps and a steel ruler and use that as a guide for cutting straight lines, and use the LARGE hole saw for cutting out the curves/corners in the windows. IE mark out the corners and drill 4 holes with the hole saw, then line up the edges of the holes with the ruler and cut straight lines with the jig saw. I'm sorry I don't have pictures of the procedure, but I hope you get what I'm saying. Then a few bux for the sand paper, or if you have a dremel, just take down the rough edges and your fine. I have yet to need a file for any of my case cutting. This all works equally well with plastic as well as metal. You just have to watch the melt factor with plastic.

Thanks clone, but not everyone has access to a water jet.
I use a jigsaw, and it works wonders...just a little fixit job with a file and some sandpaper afterwards gives me near perfect windows. However, for fan holes, i use a hole saw. Luckily, i have a drill press. I don't see how people use a hole saw with a regular hand drill. 2 large C clamps are essential for clamping down your object. Also, stick a block of wood or something under neath the cutting area.
