Have you tried the blow dryer trick? I know it sounds crazy, but it has worked for me on my Dell Inspiron and HP Pavilion. Before you spend any money on replacing anything, try this... Blow a hair dryer into the fan of your power supply, on hot, for about 30 seconds to a minute. Then turn your computer on. That's it. I learned this trick while searching for a fix for my HP - when the power supply green light was flashing. But it also worked on my Dell when the power button was flashing amber (when depressed) and wouldn't power on. You can search the web for 'power supply blow dryer' and find videos, etc. I didn't need to disconnect anything.

Would you mind if I ask you another question? Can you see it boots upto Bios display? If you can, please let me know how many rams sticks are installed on it. I hope you've connected both the power connectors. Many people make mistakes with the 4 pin power connector so they left it unconnected, and blaming other components. Without the four pin power connector, it'll never boot up only with the 20 pin connector alone. It should be connected backside of the box below the smps and behind the cpu/heatsink. If you are sure with this, the proceed. Now unplug all the external devices like usb, audio/speaker wire, ethernet. Connect only the keyboard, mouse, power cord and display/video, etc..etc... Also, unplug the internal usb, front audio, and the front panel connector, unplug the hard disk, Dvd/Cd-Rom, etc..(what I want it with only the Processor and Ram installed) .
Power on the mains and check if you can see the light on the motherboard is lit or not, if so, take a screwdriver and short the two pins of the front panel power connector (I hope you understand what i mean, if not just reply me so that I can use a labelled photos or something for your references). If it's not working, you better check the ram once again. If possible replace it with new one and try again.
Or if it's working fine and you can see that it boots upto the Bios display? then put back the components one by one while you keep booting up the system everytime a hardware is connected, that'll help you find out the culprit.
I am aware that your cabinet is the cause, means the the front panel connectors on the cabinet, let me know when you are done.
I am not done yet, but since it's better to give step by step solution than one go solution, I would await your response. Thanks.

This sure sounds like a power supply problem to me, and someone in a blog mentioned possible bad memory, but an accessory could be loading it down. Try a different power supply, and if that doesn't help, disconnect auxiliary boards and see if you get a power up. Other than that, I can't think of what it could be unless the hard drive could affect it.
Actually, I just ran across a blog about checking the PSU unit, and here is a video explaining how:
This may be your problem. Good luck, and hope this helps you.
