Ok, I got 2 13.8V 15amp identical power supplies from Radio Shack this morning. What I want to do is put them in series to get 27.6V

What do I need to do?

Following this article http://www.procooling.com/articles/h...chnology_-.php I need to unhook the ground to the chassis on one of the supplies. I popped open one unit and it is grounded to the chassis.

Here are some pics.

It is grounded through that green wire in the back. I am not sure though if that is what also grounds the 4 mounting holes? Should I make it to were there is no metal contacting the chassis?
