Detailed Look: Phanteks Enthoo Pro Exterior
The rear of the case is mostly standard, with a mount for one 120mm or 140mm case fan that can be moved up or down for more optimal airflow, and eight expansion slots. There are no holes for water cooling tubules, as both the reservoir (with included bracket) and the pump (bracket sold separately) are both installed in the interior. The 140mm fan shown is included with the case.
The I/O ports are located under the top panel, which is flipped up by pressing on the top of the door. Unlike many door panels this panel actually feels quite sturdy and not a likely candidate to snap and break like others. The Enthoo Pro features two USB 2.0 and two USB 3.0 ports, one microphone and headset jack each, and the reset button, all pretty much the standard for cases these days. And of course, the case has internal connectors for the USB ports. As the Pro does not have the outer led strips that the Primo does, there is no LED switch.
Removing the front panel reveals the mount for the front fan(s), which can accommodate anywhere from a 200mm to dual 120mm or 140mm case fans. Phanteks helpfully includes a 200mm case fan for you.
