A Closer Look - Outside
Taking a first look at the Phanteks Eclipse P300, it clearly reminds us of the slightly larger P400 (which we have not had the chance to review yet, however). The front is constructed of plastic, but comes with a metal cover, which really adds to the quality feel of the chassis. The design is dominated by slight angles, straight lines, and pronounced edges.
The main side panel of the P300 is made out of glass, but due to the unique design of the chassis, it does not need to cover the whole area as the PSU shroud takes up the bottom of the chassis. This is a pretty awesome approach because it combines the best of both worlds, a glass window and the shroud, in an efficient fashion. On the other side, a solid metal panel has been employed.
In the front, you won't find any drive bays or openings. The only vents are at the top and bottom of the chassis. You may pry the cover off to reveal two 120/140 mm fan-placement possibilities alongside the two 3.5"/2.5" drive bays on the bottom. In the rear, things look much more traditional with the PSU bay on the bottom.
That power supply bay comes with a single set of mounting holes as Phanteks envisions you to use the opening in the floor to draw fresh air in. Above that are the seven expansion slots with a removable cover each held in place by a thumb screw, which is then further secured by a movable metal plate. In the very top, you will find the only fan within the P300: a pretty basic, but high-quality 120 mm unit set to push hot air out the back of the chassis.
In the top, you will find your basic set of I/O consisting of a power button and the usual pair of USB 3.0 plugs alongside the traditional audio connectors. Phanteks has also built an LED-toggle button right into the top with which you can switch the RGB lighting's color up. In the rear is an air vent for a 120 or 140 mm fan. It is covered by a metal-mesh dust filter that is held in place with magnetic strips.
On the underside, you will find another dust filter; it protects the PSU's intake opening from dust and grime. You may easily pull that one out through the back of the case for cleaning without having to tip the entire system over.
