Where can i find housing and wiring for headers pictured below.

I would like to find housing which i can insert molex crimped wire into. It has to be female housing that I can use a desired length of wire to hook to an Arduino Uno.

where can i find this at, and what under what brand name?

An ebay search for Dupont Connector should point you in the right direction.

By far the best source for crimp connectors, precrimped wires and housings is Pololu: Pololu - Crimp Connector Housings
