Good Luck with the build. I put my own together about 3 months ago and was not too difficult (with a huge amount of help from this forum).
The amount of things that need to be plugged together can be a bit overwhelming when you start but as long as you take your time and read the motherboard manual particularly the page which labels all the various sockets for all the various cables then you will breeze through it. The manuals really are the key and that is coming from somebody who rarely reads manuals for anything.
Post lots of pic's during and after the build!
