Alright so I have never modded anything before but I really want to try this. Me and my dad are going to be doing the basic cutting out of the back panel and putting a fan there but I also want to try and put an acrylic window on the side with a hole in the side for my new zalman gfx card cooler. What I want to know, is how hard is it to really put an acrylic window in and if anyone has an good tutorials. Would I just be better off with making it a large grate on the side with a hole cut in it?
