I just receive a Cooler Master RC-130-KKN1 Elite 130 case. I want to put a 3.5 HDD on the bottom of the case. But Cooler Master state that I have to use rubber spacer to attach the HDD, but when I 'transport the case' I have to 'remove' the spacer. Has anyone put a HDD into a Elite 130 without the spacer?? And how did you do it??
