i went to home depot and bought some rotozip sabercut bits, cut out that hole in no time at all. i still have to do the intake air holes, and the in and out in the top chamber as well, but its almost 8 here and its exam week, don't wanna make too much noise. i'm afraid my neighbors are gonna call a noise complaint some time with all the building noise going on over here, although they haven't even complained to ME about it as of now. those dremels are LOUD for how small they are, but very handy anyway. i'm covered in saw dust...good thing i have a vacuum to clean the carpet up lol.
