NZXT is an interesting manufacturer. Each company that designs and manufactures cases has their strengths and weaknesses, things they're good at and things that need work, but NZXT is unique in that they're very closely related to iBuyPower (one of the biggest system building boutiques and one that's starting to threaten established brands) and tend to vend some of the most cost effective enclosures to boutiques in general, for better or worse.
Our experiences with NZXT have been mixed. The H2 when it was released suffered from a serious design flaw that drove up internal thermals (an unmarked revision was silently released later that largely resolved those problems), and the Switch 810 was a good but not great enclosure that couldn't quite live up to its promise. But today NZXT is launching the Phantom 820, a case aimed squarely at the top end of the case market where stalwarts like the Thermaltake Level 10 GT, Corsair Obsidian 800D, and SilverStone FT02 reside. It has a lot to live up to, but most impressively of all…it might actually do it.
