I wanna add a window to my lian li v1200b plus II but i dont really know what or how to do it. im wondering what a cheap jigsaw is that can get the job done as well as a cheap rotary tool maybe. Has anyone here did any window mods to the v1200 or similar as the side panal is somewhat thick almumium not cheapo tin like the videos that show you how to cut windows are so is there diff ways to cut?
