Now slide the power supply to the left slightly so that you can reach in and lift it out of the frame. As you lift the power supply, feed the cable through the hole to the other side of the fan.
For now the power supply is all you need, put everything else to the side so you have space to work. Modding the power supply This is the fun part! But before you can start snapping on the taps, some preparations need to be made.

Ideally you want all the taps in the green area. This is for the taps I used and link to in this article and the Posi-taps as well. Because they stick straight up instead of laying flat, going past the tape border might get you in a jam when you try to put the aluminum plate back in the ODD bay. Took a lot of work to get it all to fit. Thanks to this experience I now stay in the green area I show in the previous image.
The PCI cable I used and linked to at the top of this article will have 8 wires. The cables on the power supply you need are these: The two thick outer cables on both sides marked in blue are Ground. The two thick inner cables on both sides marked in yellow are 12V.

Even potentially a single video card might exceed the official limits if it needs an 8pin connection plus a 6pin connection.
