Pros: This case definitely has a lot going for it and possesses some pretty nice features. Tool-less design makes this case very easy to set up and the 3 fans keep the system cool (which can be verified using the temperature monitor conveniently located on the front of the case). The case is also very sturdy.

Cons: Temperature probes' accuracy varies depending on how well you place them. This wouldn't be a problem except for the fact that there are no instructions on how to install them, which can complicate things for those who have little to no experience building a system. The LCD display for the temperature monitor is a little bit of a space hog with regard to how it takes up the top two drive bays on the case. Although it's not too much of a problem for me, anyone who requires more than the available 3 bays may want to reconsider.

Overall Review: For those of you who don't want to read all of that up there, here's a basic summary of the case: The NZXT Guardian 921 does what you'll most likely need it to do and comes with the added conveniences of its tool-less design and temperature monitoring system.
