Okay here's the deal....I bought a cheap Xdreamer case off of newegg...and I modded it, and put fans all over it....(you can see the mods at http://images.pyrospheric.net/ ) but in the process of cutting the fan holes for my 2 92mm fans in the window, I cracked it pretty good. The problem is that I don't know if the window is plexiglass or lexan or what. I wonder what is easier to cut? also, I am wondering if anybody has any suggestions for a better way to cut out fan holes and thier associated screw holes. I really want to finish this case up and have it looking good, but I need to get a nice window first! if anyone has a tip or a link or advice, please let me know! Thanks in advance!
