Phanteks have made a lot of nice chassis lately and the P400 is a great addition to the lineup, in a perfect world I would love to see an optional drive bay in the front and a selection of different front panels for the case - that front panel sure comes off easy and there are no wires connected to it :)

This case is spectacular. It's aesthetics are great, and the RGB front panel combined with the Phanteks RGB strip really makes for a nice look. The only complaint that I have is that the window goes all the way down to the bottom of the compartment, so if you are using an LED strip, there is no way to set it beneath the glass so that only the light is visible.. That's a small complaint, but it bothers me a bit. Overall the case design, cable management, and aesthetics are awesome. 5 stars, easily one of my new favorite cases.

One note: If you are using a modular PSU, hook up the cables you are going to use before you mount it, because it is nearly impossible to hook up cables once the PSU is mounted, especially for people with bigger hands.

Phenomenal cable management for those that lack there of. Only downsides were this being a fingerprint magnet and the front-facing panel was tough to get off for me. Took me a piece of cloth, a butter knife, and a rubber spatula to take it off! Still my favorite case though, I highly recommend it.

Great Budget case. Plenty room for cable management. Easy to work with

Just an awesome looking case with a durable window. It was so nice working inside the case as I built the pc. The front cover comes off easily, almost too easily, and is filtered throughout. Again, I love the exterior LED's which allows me to personalize it to my taste. And it is aesthetically pleasing presenting a tough look.........perfect for the War Machine.

Modern and Sleek design. LED control and adapter for additional LED strip. More than enough space for any moderate build.

I've heard complaints about this but honestly this might be my favorite case, especially for cable management! The RGB lights are nice but I also am kinda disappointed they didn't give out free strips, would've been nice since now I have to buy a separate $20 pair. So be wary of that. Building in this case wasn't too hard but I saw myself constantly watching every step because I didn't want to scratch it which the inevitable happened regardless. Over all the case has looks going for it but keep in mind how sensitive this thing can be. It is a fingerprint magnet! but at least it has really good dust filters.

I **** with this case

holy **** this case is sick. grommets, lots of cable management room, 2 drive caddies, 2 SSD brackets psu shroud, comes with ties, built in LEDs, a port to add an LED strip that will sync with the built in ones, minimalist style, and for about $70. I am so glad i decided to get this case, its my favorite part of my build.

Nice looking case with lots of features at a price that my wallet can deal with

bhsnipes 11 points 27 months ago

Perhaps the best case I've seen at this price point. It includes features that you would normally see in a $100+ case.

Nice cable management with Rubber grommets. LED lighting, dust filters, and a separate enclosure for the PSU.
