Can't get my computer to boot after making some changes...

Ok, I have the following:
Epox 8k3a+ and XP 1700

I had to mod my case to add a couple other hard drives to my case (they are going to be mounted on the floor of my case), which included drilling some holes into my case. Anyways, after putting everything back in the case, I tried booting up with all my original equipment and it didn't post. My mobo has some indicator leds and "led 3" was lit up red. Apparently, that led indicates that the board doesn't have power. I stripped everything down and removed evertyhing except my cpu, memory, and vid card. I tried booting and nothing happened this time when I pressed the power button except it looked like it was going to turn on since the fans had just started to spin, but then it just shut right back down.

I was frustrated so I ripped out another power supply from a different case and hooked up the ATX power connector and only the molex connectors for fans and tried again. However, I still had the same problem as before. The red led 3 was lit up and only my fans spun.

I tried clearing my CMOS and checked the atx power connection several different times, but I still have that same issue. Any idea?

I should also mention that this board has the idicator codes via a led panel on the board itself, but I don't receive any codes from that since apparently the board thinks it is not getting power.

I know its a pain, but have you tried to remove the mobo from the case & do a "bare bones" setup.
Did you take the board out to the drilling & was it an electric drill?

If it doesn't have power what is powering the LED?
Are you sure you didn't cut any wires while you were drilling?
Keep in mind that the cases are designed with proper airflow in mind.  When you modify it in this way you can create an overheating situation.

You may have shorted out the board.  Try swapping in a new one.

2nd ide channel ( mobo ), cable or HD is causing problem. Try different HD and/or cable swapping to see which it is.

Ok, this was the deal:

The reason it wasn't working when the sec. IDE was plugged in is because only one of the two ATAPI devices on the channel were connected to power.  The master had power, but the slave didn't.  I didn't think that would cause a problem, but it did.

Have you tried changing RAM slots or even the chips

Did you drill holes with the motherboard in the case?

If so, you probably have covered the board with metal chips which do a great job of shorting out signals.

Remove the MB from the case and try cleaning the metal chips off with compressed air and/or a vacuum cleaner taking care not to damage anything.

It's also entirely possible that you've ruined your motherboard.
