The whole front panel can also be taken off easily by pulling at its bottom. The panel and the door are all plastic. The Phantom has five 5.25-inch bays but does not allow installing 3.5-inch devices into them. You can install a 120 or 140mm fan at the bottom of the front panel and we used this opportunity in our tests by putting a 120mm fan there although there was no dust filter for it in the Phantom kit. The vent grid between the front fan and the HDD rack is rather too small, by the way.
On the left panel, behind a black metallic mesh and a dust filter, there are two 120mm fans (DF1202512RFLN, 0.16 A, 1.92 W, 1300 RPM, 3-pin connection) that are meant to cool the HDD racks. The fan cables are 51 centimeters long; there is a plastic holder for them on the side panel. Here you can also see a place for a 200 or 230mm fan that can cool the mainboard and CPU cooler. The manufacturer proposes that you install NZXT’s own FN-200RB or FS-200LED fan here.
The right panel has a trapezoid vent grid for cooling the HDD racks. That's all we can tell you about it, so let's move on.
The side panels are fixed in place with three thumbscrews. The central screw is special. You can just push it down without actually unfastening it.
A button for turning on the top fan's highlighting can be found at the top of the back panel. Below it there is an exhaust 120mm fan like those on the side panel. It's placed behind a honeycomb vent grid which is not actually very transparent for the air flow. There are as many as four openings for the pipes of a liquid cooling system. They are rubberized and large, over 2 centimeters in diameter. Next go seven expansion-card brackets made from a fine metallic black mesh. Like in most of today’s system cases, the PSU bay is at the very bottom. The mounting holes allow positioning the PSU in either way: with its fan facing up or down.
So, we’ve finally got to the bottom of the Phantom. The bottom panel is perforated below the HDD racks. There is some perforation below the PSU bay, too, which is covered with a removable dust filter. The filter isn’t fastened properly, though. It's easy to take the filter out, but there is a rather large gap between it and the bottom panel. The perforation area is small. It is made to match a 120mm fan, although today's PSUs often come with 140mm fans. Besides, even a 120mm fan is likely to be not exactly in the middle of a PSU case.
The Phantom stands on long 2cm skids that have rubber strips glued to them from below.
The interior of this system case is huge. You can see two rows of rubberized cutouts in the mainboard’s mounting plate to hide cables behind it. The mainboard is installed on standard posts but there are only nine of them included into the kit. The Phantom can accommodate mainboards of many different form-factors: ATX, Extended ATX, Flex ATX, Micro ATX, and Mini-ITX. Every mounting hole is labeled and there is a description of the labels in the middle of the mainboard's mounting plate.
This huge interior allows you to have not one but two HDD racks. The main one is for five devices while the other one can take in only two HDDs. The second rack is removable, so you can easily take it off altogether. There are also five 5.25-inch bays in the top right corner of the chassis.
There is a compartment for hiding cables behind the mainboard. It is less than 2 centimeters wide, but that's enough.
The expansion-card slots are covered with black brackets fastened with thumbscrews. There are holes in the folded part of the back panel for accessing them.
