It isn't complicated. Just place in the hard-ware, and connect the cords in the proper areas. The one area you may have a problem with is the small connection wires... the ones where you have to connect the power LED, the HDD switch, the speaker, and all of those other small ones onto the motherboard. That's sometimes a pain in the rear end. But other then that it is simple. Make sure your fingers have no static on them and you aren't working near a static heavy surfaces.
