Building a rig is super easy. Have you ever changed a component in a pc? RAM, HD, or Video Card? It is the same, only repeated a few more times, then install the OS and you are good. If you have never changed a component in a pc before, mining efficiently might be above your current skill level. Getting the hardware is only the first step. To get the most out of your machine, you need to be comfortable working with your gear. Overclocking, cooling, and being able to quickly diagnose issues are prerequisites to running a profitable mining rig. This rush is a great time to learn these things though. If you hit problems, try to distill them down to the most basic keywords, then google will have an answer for anything you come across.
