Pros: Easy to follow printed manual, looks pretty good, good feature set
Cons: Different in size to conventional ATX mobo's, but wasn't a massive problem.
I bought this mobo for my 1st ever PC build, I was a little nervous, but all was made easy because of the good instructions in the ASRock Z77 Extreme4's printed manual. Some of the printed material is a little small, but there are more detailed explanations of everything in latter parts of the manual. The handy little LED number display will show you if and what is causing a problem should a component be faulty/poorly-installed during post.
