I saw that pr, I have been a tech junky for a long time and what I find totally amazing is how far we have come in a few years. Even look at the MP3 players out there now. They have them that they are the size of a half a pack of smokes meaning half the size top to bottom that can hold two and a half hours roughly of music. Remember the old bulky machines that could not hold 1/10th of that not that many years ago?
I have never built my own system, thought about it a few times and ended up just buying them instead..lol I am sure there is a satisfaction to be had building them yourself.
