To gain access to the interior of the chassis, simply remove the thumbscrews holding each panel in place. Sound dampening material has been applied to both sides of these parts to further encapsulate any noise from within. Taking a quick first look at the interior, everything is where you would expect it to be. While the case has similarities to the Phantom 410 or Tempest 410, NZXT has changed a few things around to update the overall design. Turning the case around, one can see a large opening in the motherboard tray and holes running along the edge of the tray in an L-shaped layout. Unfortunately, the H230 does not include rubber grommets, so the chassis may not look as tidy in the end, with everything wired up.
Most of the changes over the Phantom 410 or Tempest 410 can be found in the front of the interior. NZXT has included two hard-drive cages similar to those found in the Phantom 530, for example. Each of these can hold up to three 3.5" or 2.5" hard drives. You may also take the top cage out to create more space for a large graphics cards, for example. Doing so reveals a fan mounting position behind some dust filters and the 120 mm unit NZXT included in the bottom of the front. Just like in the Phantom, each hard-drive tray may also be removed by pulling it toward the motherboard tray and out the right side of the case.
The PSU bay in the rear is quite simple but effective. The installed unit rests on four tiny rubber bumps to keep vibrations away from the chassis frame—at least as long as there is very little of it. Above that are the seven motherboard-expansion slots, each protected by an individual metal mesh cover held in place by thumbscrews. NZXT also pre-installed white-bladed fans into the chassis.
Before we dive into the assembly process, let us take a quick look at the cables. All of them are black to go with the looks of the chassis. While those for the case are of the usual kind, all the fans within the NZXT H230 come equipped with both a 3-pin and Molex connector for utmost flexibility. Last but not least, the I/O cables are of the usual kind, and the chassis ships with an internal 20-pin USB 3.0 connector.
