Simplify the trouble-shooting by unplugging most components and starting with just the PSU, motherboard, CPU and RAM. Then gradually plug in fans, hard-drives, etc.

If you test with a PSU that is known to work and yet the system will exhibit the same behaviour then it's most likely the mobo''s fault.
Edit:
I see in your signiture that you also have a Earthwatts 500W? Try using that for the test....

then try powering it up

I personally had problems with a new DOA mobo that exhibited the issues as yours, but there are others who described simillar symptomps but the cause was different ranging from defective PSU to discrete video card.
Since your system only quirk seems to be the PSU and the video output comes from the IGP, naturally i suspect the PSU or the motherboard. That said we aren't magicians, unless you start actually testing parts yourself we can't do anything. It's clear that you have enough knowledge with DIY builds, i doubt the mobo speaker would help. It usuually does if the mobo works and we haven't established that yet. Maybe i'm crazy but i sense a touch of sarcasm in your tone.
Is this thread even for a real system? I'm having doubts right now due to your responses.

I recently got more memory and in order to install it I disconnected the cables that went to the front of my board (HD/Power/Reset/Speaker). When I reconnected them and tried to power up the computer I got into a similar situation where I could see the fans spin up for a few seconds, stop and then restart about ten seconds later. It kept doing that forever. It turns out that when reconnecting the cables I had put some in the wrong spot. (Easy to do since they were all together and had no keying to prevent you from making a mistake.)
It took me a few minutes to figure out what was causing the problem but once I reconnected the wires in the proper order everything worked great and the system booted up as it should.

Does your case even have the speaker? Not many do these days.

Even if it is correctly placed, there could be an extra standoff underneath that does not correspond to a motherboard mounting hole.
