Do you have an LED on the MB?
You say you breadboarded. How did you turn the system on? The case button or?
Do you have a MB speaker?
Initially the PSU power, then the case button, when nothing happened, I unplugged all of the front panel connections and just used the PSU power button. Intially I had a MB speaker, no noise, no fans, no smell. Nothing, like it isn't getting any power.
