NZXT are a well known company for their computer cases and case accessories. They focus almost entirely on these, with the only exception being the latest series of power supplies. They also design most of their products for gamers and modders, therefore they sport an exotic and unique appearance. We reviewed many of NZXT's cases in the past and today we will review one of their latest additions to their products range, the Guardian 921. The Guardian 921 is designed to offer the best value for your money, being loaded with a lot of features and with a unique but not kitschy exterior. We will carefully examine the case and its features in this review.
