NZXT has tried pushing into the 200+ USD case market before, and while the Khaos was an interesting case, its overall success was limited. NZXT has now taken the Phantom and grown it out into a fully-fledged monster. "Not only bigger, but better" holds true here. Every aspect of the original has been evolved and improved upon. NZXT has also kept enough original design elements to make it a clear member of the Phantom family. There are a few small shortcomings like its fragile HDD trays or a lot of messy cables, but the Phantom 820 does, ultimately, impress.
Especially the multi-color LEDs, embedded not only into the exterior design of the chassis, but also within the case itself, make the case stick out – here is something you won't find in any other chassis. Add the well-engineered four-channel fan controller and the white LEDs in the back, and the case doesn't only end up looking great, but does so while offering the guts you would be looking for in a case of this price category. It feels like NZXT has finally managed to break the 200 USD price barrier by securing itself a spot in the big-tower and high-price segment with the Phantom 820. Well done NZXT, well done.
