by tracing the contour of the window on your case. Then do the
marks for the screws, which will be holding the window in place.
Once you are done its time to cut and pierce. Here is a picture
of the hole I did on top of my case for the window; you can
also build nice weapons with the metal scrap pieces.
the window itself I use Plexiglas because it's cheap (both pieces
cost less then $10) and easy to work with. Remember that your
window has to be a little bigger than the hole so you can screw
it on. The Plexiglas I used is 1/8" thick, which makes it very
easy to cut with a jigsaw, but you should still be careful.
I have a little trick to make sure that the screw holes on the
window and the ones on the case will match, make the holes in
the case first, and then place the window where you want. You
will see the holes you did in your case through the Plexiglas.
Take a marker and do a little dot over each hole. This will
give you a perfect match. You can see what I mean on the next
