Check out the stickies in the section. They have all the info you need on building. It shows a couple guy's builds all the way through the process, and another member made an awesome walk-through with pictures on how to build a lower. If you have some specific questions after looking through that, just let us know.
Oh, and drop by the introductions section to let us know a little bit about yourself.
