I feel Anandtech has what I consider the overall most trustworthy reviews, and in many ways the most insightful as well. Quality is high, quantity not so much. I don't know any site that has been so consistently strong for so long.
For cases I like the GamersNexus youtube channel, however the videos are interminably long. I've found that starting 5 minutes in is a safe way to skip some of the repetitive ramble, and any gripes I skipped over will get repeated at least four more times.
