5. In the center, note that the fan plugs on the right are left in place (see Brett pic #7 for a closer shot). Only the two on the left have to be removed. Brett points to them, but you can see in his fan pic that they're still attached. There are two clips on the top right fan that hold the harness for the connectors that have to be removed. One of mine was broken, so I was lucky I guess. But don't forget them.
