To gain access to the interior of the chassis, simply remove the thumbscrews holding each panel in place. Taking a quick first look at the interior, everything is where you would expect it to be. 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 Phantom 240 does not include rubber grommets, so the chassis may not look as tidy in the end, after everything has been wired up—something that is rather important due to the large window. There is also only 17 mm of space to work with between the motherboard tray and the side panel, which makes the task of creating a clean system even harder.
Some of the larger Phantom's features can be found in the front of the interior. NZXT 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. Doing so reveals a fan-mounting possibility and the retail 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 through the right side.
The PSU bay in the rear is quite simple but effective. The installed unit rests on four tiny rubber bumps to kill any vibrations—as long as there is not too much. Above that are the seven motherboard-expansion slots, each protected by its individual metal mesh cover thumbscrews hold in place. NZXT also pre-installed white-bladed fans into the chassis.
You may install another fan on the floor of the chassis, which, while nice, is not very useful most of the time. Odds are your PSU will cover some of it up anyways. There is enough room between the frame and its top cover for you to place the radiator's fans on top straight on the ceiling, for example, which saves you some precious space.
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. The case and I/O cables are of the usual kind, shipping with an internal 20-pin USB 3.0 connector. Last but not least, the 3-pin-header-equipped fans come with a single Molex adapter, each.
