You will need a Dremel, jigsaw, or other cutting tool, which can cut through the metal of your case. As always I will be using my Dremel, I have a fiberglass reinforced cutoff wheel attached. Also be sure to always wear safety glasses of some kind, you don’t want to get case shrapnel in your eyes. Also a dust mask is also suggested to keep all the stuff flying around the air out of your lungs.
Go ahead and start cutting along the outermost line, take your time and be patient. Here’s a picture of the cutting process being about half done, see why the mask is a good idea?
4 cutoff wheels later and about 20 minutes of cutting and I am done.
Here’s the big piece I just cut out of my case, go ahead and throw it in the trash or do whatever you like with it
As you can see from the picture it is a good idea to grind down the edges so they are not sharp and jagged, trust me they can hurt. Go ahead and use some kind of grinding stone with your Dremel or a file if you do not have a Dremel.
After you have the edges smooth enough so you wont cut yourself go ahead and clean off all the mess from cutting. Your hole should be about 1/8″ larger than the window now.
