A Closer Look - Inside

Removing the side panels, it now becomes apparent that Phanteks does not ship any fans with the chassis. They recently launched their SK line of fans, which should fit in here well. While this is not the end of the world, at least one fan in the rear of the chassis would have been helpful. That said, Phanteks is aiming this case clearly at those who either need massive amounts of storage or anyone really going for a dual-system setup out of the box. The steel side panel comes with two magnetic metal mesh covers that protect both openings from any coarser dirt entering the interior.


Four covers in the front fill the side opening next to the motherboard tray. These may not look like much at this angle, but you may actually install a 2.5" drive on each by simply clipping the drive into place. As is pretty much customary with Phanteks cases, there are several Velcro strips for cable management, along with three further 2.5" SSD placement possibilities for traditional trays. That brings the total drive count for this format to seven just on this side of the chassis.


The PSU is is lined with foam elements as an anti-vibration measure, and there is a metal cover for easier and cleaner cable management. You may flip it down to reveal the opening through which any cables for the ITX system should be routed.


Looking at the front, you can clearly see the fabric-covered mesh opening where you could install your intake fans. On top, the four individual plastic covers for the side-mounting position fill the gaps that allow for up to four 120 mm fans or yet another 480 mm radiator. You may also install an SSD on top of these covers for it to be clearly visible inside the running system. That brings the total number for such drives to a whooping eleven within the Phanteks Enthoo Pro II. With the four 3.5" cages, that total climbs to a whooping fifteen.


On the floor of the chassis is yet another possibility for up to three 120 mm fans or a 360 mm radiator. In case you are not keeping count, that means the Enthoo Pro II can hold two 480 and two 360 mm radiators without issue. That said, you would loose out on all but three 2.5" drive bays if you go all out with liquid cooling.


On the bottom of the rear is a little PSU shroud to keep the cable mess away from the interior. While it looks like it is lined with a cool ARGB strip, and the product pictures on Phanteks website make it look like there is one, the chassis actually lacks this extra. This is also where you would mount your secondary ITX system. However, to use it with a dedicated GPU, you will have to buy an optional accessory in the form of a vertical GPU mount and are required to go with liquid cooling for the CPU as an air cooler would no longer fit alongside the graphics card. Alternatively, if you are not going with a dual-system setup or liquid cooling on the floor, you may stack your four 3.5" cages in this area instead. Above that are the expansion slots, which allows for yet another vertically mounted GPU with an optional accessory. Thanks to the three slots, even the biggest GPUs should fit without issue. In the very top, things look quite traditional with the aforementioned fan-mounting possibility.


Taking a quick look at the ceiling, you can also see where the fans or radiator would be mounted here. There is plenty of room between such elements and the motherboard, so you should run into no issues with even a thick radiator.


All the cables within the Phanteks Enthoo Pro II are of the default variety. Phanteks does not include two full sets of cables for the power and reset buttons, or LEDs, but instead added a label to the primary reset and HDD activity LED leads meant be used as the power button and LED for the ITX system. As the Enthoo Pro II comes with a built-in ARGB controller (or DRGB as they call it), you may further expand them with both their own proprietary connector or a generic one, so feel free to buy fans/LED strips of your choosing.
