Phanteks Eclipse P350X Review

Günstiger Midi-Tower mit RGB-Beleuchtung und Hartglas-Seitenpanel

With the Eclipse P350X, Phanteks has released a new entry-level case for motherboards up to E-ATX format, which despite its low price will impress with numerous features. The compact Midi Tower is equipped with RGB lighting in front and side. There is also a large tempered glass window on the left side. As it is now standard with the better cases, a power supply cover is not dispensed with either.

All in all the specifications of the Phantek Eclipse P350X read very well and sound like more than a price of only € 143.00*. If and where Phanteks makes cuts to reach this price, we clarify in the following test report for you.

Scope of Delivery

The Phanteks Eclipse P350X Midi-Tower is well and safely packed. Due to the Tempered Glass side, this must also be the case. We find the accessories in a cardboard box in the front, where the hard disk cages are hidden. Beside some cable ties all necessary screws are present here. We also find a small manual that explains the most important features. This is particularly useful for RGB lighting.

Two SSD mounts are already mounted, as are the fan and two HDD mounts. Also the spacers for the mainboard are pre-installed. So you can start directly with the system construction.


With its design, the Phanteks Eclipse series is aimed at gamers. This is also the case with the Phanteks Eclipse P350X. Optically, it stands out from the crowd without exaggerating. The case is relatively plain black, just like the Eclipse P300. The large tempered glass pane on the left side is conspicuous at first glance. It does not extend over the entire side, but starts above the power supply cover. The hardware can then be inspected here. But at second glance we find even more striking differences.

Especially with RGB lighting you can upgrade your gaming system significantly. Since Phanteks only have an indirect influence on the interior, the manufacturer starts with the RGB lighting outside the housing. There are two LED strips on the front. Also between the power supply cover and the glass pane. The lighting can be controlled either via two switches on the I/O panel, or via a 3-pin RGB header from a compatible motherboard. Yeah, you read right – 3-pin. What’s the meaning of this?

The RGB lighting is digital and therefore addressable. The LED strips can therefore not only light up in one colour, but in several at the same time. It’s especially cool when the fan, mainboard and graphics card are also equipped with digital RGB lighting and you can chase a light wave or similar through the hardware. Synchronization with other peripheral devices is also conceivable. Asus supports this with its Aura software, for example. But the other manufacturers with digital 3-pin RGB headers are of course also compatible. Other RGB products from Phanteks can easily be connected in series to connect additional LED strips or fans, for example.

Inside, Phanteks gives its customers the choice – either white or black. From the outside, the case is only available in black, at least until now. We decided to test the completely black version.

As mentioned above, the I/O panel of the Phanteks Eclipse P350X has two switches to control the RGB lighting. There is also a microphone input and an audio output. Two USB 3.0 ports are also still available. The I/O panel is located in the front area of the upper side of the housing.

On the positive side, Phanteks was concerned about the proper routing of the cables. Through various openings in the mainboard tray the cables can be laid cleanly and hidden for the most part. Especially the power supply cover contributes to this.
