Step 4Various Things...
Some various things to do to complete the project.
First, attach the thicker fan. You want to place it so that it's blowing INTO the case (there should be some arrows in the plastic near where the wires connect to show you how the air flows. You might have to cut off all the other plastic tabs on the fan to make it fit against the side of the box and mesh with the component board. Using a couple small screws that fit in the holes in the fan (and in the holes you cut in the box), attach the fan and a fan grill. You'll probably only be able to attach 2 screws. Then, using some needle-nosed pliers, bend the two remaining "arms" on the fan grill 90 degrees to make little feet. These will hold the fan up off the surface its on so it will be able to get decent air flow.
Next!
Using some thermal tape or thermal compound, attach the heatsink to the top of the Peltier unit. The heatsink basically just rests on top of the case. I used thermal tape to hold things together, but if you use thermal compound, you'll probably have to engineer some sort of brace system to hold them together.
Cut a piece of thin plastic (3rd picture) to use (1) to prevent a short circuit between the transformer and a switch and (2) to prevent all your chilled air from blowing past the hot components and coming out hot. Some air will be blown past them to cool it a bit, but not as much as there would have if the plastic was not in place. You'll need to tinker around with cutting sections out of the plastic for the wires to go through.
Just sort of place the PC board as close to the side of the case as possible so that the fan will fit. Make sure there aren't any short circuits! You can add a bit of hot glue to keep it on the side, but I find that the fan pushing against it works well enough. Plus, I was out of hot glue.
And....
Finally, grab your AC plug with a cable, strip the wires inside as well as the wires to the transformer, insulate everything, and solder the one wire form the transformer to one wire of the plug. Do the same with the other wires.

Can you say where you got the thermal tape from? Thaaanx.
