Next, we removed the side steel panels and the ABS plastic ones in order to have an unobstructed view of the interior of the Phantom 630. The casing can fit up to an XL-ATX sized motherboard (such as this and this). For graphics cards, it can accommodate those with lengths up to 12.7-inch. As the chassis features removable 3.5-inch drive cages, the chassis can actually fit cards that are also much longer than that!
On the other side of the chassis, we see a large cut-out on the motherboard tray to facilitate high-end CPU cooler back plate installations, and the rubber grommets that cover the cut-outs set aside for internal cable management purposes. Also, notice the two removable 2.5-inch drive mounting trays located below the motherboard tray cut-out? Since this side of the casing will service the connectivity of the storage bays, we figure that NZXT thought it would be apt to maximize further drive mounting options. It's not a bad idea considering it's designed for mounting SSD drives.
At the edge of the motherboard tray's cut-out, there is a fan connector circuit board. It is linked to the fan speed control switch, which is located at the top control panel of the casing. As a result, any cooling fan that is connected to this circuit board, will have its speed centrally controlled by the fan speed switch. Up to a total of ten cooling fans can be connected to the circuit board.
Next, we focus on the rear and bottom of the Phantom 630, but from the interior this time round:-
The casing's motherboard tray has some of the commonly used standoffs pre-installed. There are even markings to indicate which of the mounting holes are in use for the various board form factors.
For storage matters, the NZXT Phantom 630 comes with three removable 3.5-inch drive enclosures (1x large, 1x medium, 1x small) and they can be stacked according to the requirements of the system builder for a grand total of six 3.5-inch internal drives. They feature plastic trays for a tool-free installation experience of each 3.5-inch drive. Some of these 3.5-inch drive enclosures can be removed to make way for a massively long graphics card, but we doubt the need will arise given the size of the casing and that most conform to standard lengths.
Located above the 3.5-inch drive enclosures are the 5.25-inch drive bays that feature latching mechanisms for installation convenience. On the other side of each slot, there are two screw holes for using the bundled 6-23 screws, which can be used for additional fastening of the installed 5.25-inch drive.
Next, we stripped the casing's front and top to see what's really underneath. On the front, we see the supplied 200mm intake fan. While that should more than suffice, the front mount is able to accommodate a pair of 140mm intake cooling fans for more direct drive ventilation.
Similarly on the top, there's a cooling fan that measures 200mm that can be swapped out for a pair of 140mm outlet fans or a triplet of 120mm ones. Take note that the filters would have to be removed if you are installing the alternative fans as they are meant for the 200mm fans. In this regard, it's quite likely that the optional mounting option were more for installation of respective water cooling radiators from underneath the top panel rather than replacing the 200mm fans.
There is yet another huge 200mm cooling fan located on one of its side metal panel with the same plastic mesh filter. You can extend the fan's power connector to the fan connector circuit board, and once connected, the cooling fan can be centrally controlled too.
As a note to our readers, the instruction manual of the Phantom 630 also details the installation instructions for the possible configurations of liquid cooling solutions. This is one of the unique features of this chassis, the flexibility of the supported cooling configurations, on top of their generous bundle of cooling fans.
