Full Disclosure: I was given all the products in this video by the respective manufacturers for the purpose of making review or instructional videos. The exception is the Noctua fans which I purchased on Ebay. I do not accept payment from the manufacturers, and I do my best to present unbiased information to you, my viewers. i.e. Just because it was given to me doesn't mean I'm going to say good things about it. If it's crap, I will tell you. Unfortunately, these videos do not generate enough income to purchase the products I review. Therefore, I have to ask the respective companies to give them to me, and if a company is not willing to provide the unit I do not make a review.
