Beautiful case at a solid price point.

Mentioned that it was my 2nd build ever, which the first one had the CoolerMaster 690. When I was moving, I didn't have the room to take the case, but I kept the components which I later on put inside a Silverstone as HTPC. Now I see how far the cases how come, that all the details have been well thought. Very easy cable management, it pleases the eye. One thing I could say is about the dust. I choose it to be a glass panel with the RGB. But if leave the case on the floor, and choose to go with the fans provided , you would get some dust, and trust me they don't look to well in the pictures. Otherwise everything is perfect.

Pretty case. Great RGB and storage for all my gear. Looking forward to a second Phantex case in future though as my cable management at the moment (while completely my responsibility) is a bit sh** due to me kinda not realising that I can put smaller cables under the mobo.

Cable management was all I needed and this provided that. Thanks Phanteks

Nice case; not too expensive yet it has the functions of a high end case

What a case. This thing is absolutely amazing to work with. The cable management is glorious, even for a newbie builder like myself. The colors are a nice touch, Should have gotten the sound blocking one though (The p400s I believe). When my fans ramp up it sounds like a hollow tube. Spend the extra money, you won't regret it.

Great case! Amazing to work in, very nice to look at. Airflow seems sufficient. Cable management is excellent due to the wealth of cable cutouts, tie-down points, and the Velcro straps included behind the motherboard tray. Comes with an RGB LED strip which connects and syncs with the logo lighting and the power button LED. My only complaint is that Phanteks should have included an adapter in the box that allows you to connect the RGB strip and other case lighting to the motherboard header. You can definitely buy an inexpensive adapter that Phanteks makes, and the process is very simple, but this part should have been included in the box. Still well worth the five stars, especially for the price.

Amazing case. Comes with a magnetic RGB strip that works well. Was a breeze to build in.
