I just put this (http://www.tomshardware.com/forum/250131-31-media-built-feedback-welcome) together inside a different case (Antec Fusion Black 430, with a 500W PSU instead of stock). The motherboard I chose has 4 pins for a speaker, but the case has nothing to put on these pins. So, I put in PSU, CPU, HSF, and turn on, and the machine doesn't enter post. No beeps. I can't tell if it's because the case had no speaker to plug into those 4 pins? (Although it does have front panel audio which is plugged into the mobo.) Or is it something wrong with CPU or mobo? Fans all go on just fine.
