ATX power supply in a cd drive case

This instructable will show you how to make an external ATX power supply.
Now many other people have done something like this before, mine is different in the way that the power supply is replaceable and the case and many of the parts came from an old computer (yay recycling).
As you can see, the main reason why I built this is to power my camera for some time lapse and some long exposures, something the batteries just coulden't do.

Step 1 Parts

Ok let's get started. You will hear this alot in this 'structable but if something isn't clear in my pictures or my description, check some other great people that have done ATX mods, their instructions are better than mine.

Now, parts, I just went to the shack and grabbed all the stuff I needed, you can slowly gather the parts from used audio amps and stuff, but I kinda needed this to work soon so I just bought it. Total cost was near $25 but I had a few of the needed parts already.

You will need the usual 10ohm 10watt sand resistors
LED's
Solder
a switch (I made the mistake of buying a lit switch, the extra load to light the switch won't turn the PSU on, so get just a regular switch. As an override, I just shorted out the terminals, I'll get a different switch later)
other random stuff, you should probably read through this whole thing before starting your project.
