Making my own power switch connectors for mobo?

I am transferring a new motherboard to an old case. Problem is, the power sw, reset, etc are on one ribbon and that is connected to a circuit board. I would like to make my own power switch or at least link it to an existing switch on the case. I am looking for the plastic piece that connects the pins to the wire. They are either single or double, allowing one or two pins to be connected.
Does anyone know the proper name for these plastic pin connectors that I can connect a wire and attach it to a pin?
I dont know where I can buy these plastic connectors. Anyone know?

I can't remember what they are called but they are modular and can be reconfigured. By using a pin or the tip of a hobby knife, the individual wires and conncectors can be removed from the plastic housing. If your case or an old case has an extra wire for turbo switch or green led or something, cut it out and attach it to the switch on the case you want to use. With a little research and disassebly, its a good learning project and mod. I have chaged connectors from 2 pin to 3 and vice versa many times.

How do you use a hobby knife of other tool to remove the wires from the block pin connectors (and to add other wires)? Also, some blocks have a blocked pin. I wonder if I can remove that too.
