Is anything pressing against the Clear CMOS button on the backside of the I/O panel? Sometimes the panels are not punched out. If that button is being pressed, it will not power on. I see no other jumpers in the manual that I would suggest checking other than that button.

Check the cable connections coming into the board and your mounting points in your case. Pull all the motherboard attached cables off USB, Firewire, Power button, etc (except power) and use the onboard power button to start the computer. Drives, memory, CPU do not cause a motherboard to not power on. A failure of those components will typically cause a power on with no POST or a power on with a sudden power off. Power and or grounding are usually suspect for your issue.

Try a different power supply and then lastly, DOA motherboard. It happens.
