Can this be done without modding the case . I want to keep a dvd drive and one harddrive in there . I seen you can mount on of the hd's on top but I have no place to mount the dvd drive. Im not sure if it could fit at the bottom and I've looked around here for about 1hr and I cant find someone that has done it without cutting their case . A big thanks if someone could give me some options. Can it fit on the bottom with the motherboard installed ?
