Good video, one thing I'd recommend is when you mention a part to have a picture of it displayed, it makes it a lot easier for me to understand what you're recommending if I can visualize it when you say it.
Some constructive critism, you start off a bit shaky and get more confident as you go. Could I recommend you read through a script while you record and after you are done lauch to the stat again? It would help you take a good take.
One quiery for you, you went with the MSI FM2-A55M-E33 as opposed to the ASRock FM2A75M. Any particular reason?
I do like that it has HDMI and is 10 dollars cheaper on Newegg.
