    Good airflow, amazing cable management, easy to build in. Unfortunately it doesn't come with a fan hub with everything pre-wired to it like the H510i and H510 Elite does but the airflow and price point it's at compared to those swayed me towards Phanteks.

    Top radiator support would make this the perfect case and would blow the Meshify C out of the water, but I specifically went with this because of the front panel look but previous P400 models never had it and I don't think it'd be possible without a new series of cases.

    Realistically though, a front USB-C port, included vertical GPU mount, and sound dampening material (P400SA maybe?) would really make Fractal Design sweat on the next refresh of the P series.

    This was a pretty easy case choice, as i've been looking a these for quite a while. I love the front pannel, cable management is so easy. Only complaint is that the roof of the case should be a little higher to fit the larger style of case fans.

    Case was way bigger than expected, but not too much of a problem. Really sleek design and amazing airflow. The fine mesh is something other cases should take note of. Cable management was fairly easy in this too for a first time builder.

    Great case from a great company. Excellent air flow, and the fans are quiet. Good cable management. I had an issue with one of the front case fans, wobble, so I reached out to Phanteks customer support. Sent them a short video clip of the issue, and proof of purchase, and they sent out a new fan the same day. If you want a simple rgb case that's quiet, cool, and provides good cable management this is the one to get.

    I love this case because of the quality, price, and features it came with. 3 RGB fans, radiator support for the front (up to 360), radiator support on the top of the case (240), PSU shroud, mesh front cover, etc. Build quality was solid, tempered glass side panel is a plus as well.

    from completed build Dee's Build (AMD - 3600)

    I've built in the older version P400 and P400S cases before. Those had less RGB so it wasn't as much of an issue. With this case, the instructions were a bit minimal, so when it got to the fans being powered and RGB working, it was a bit more confusing. It took me a while to find all the fan powering cables because of the neatly bundled cables from the case. Overall, the case is great to work with, and the mesh on the front panel, top and rear provide optimal cooling. I'm running air cooling only on my build and I have hovering temperatures around 45-50C. Would definitely buy again.

    This case was extremely easy to build in. The rgb fans were a little confusing but I figured that out eventually. There is a decent amount of space in the back for cable management and the velcro tie downs worked well. All in all I would definitely recommend, especially if you are looking for nice rgb fans included with the case. I will be using this in my new build in the coming months.

    Man what a solid case. Been excited to get one since they were released, and I am not disappointed. Would recommend to anyone who is in the market with a budget of $100 on their case. My second Phanteks case, first being the Enthoo 719, and I don't see myself veering away from them. I've had probably every manufacturer, or at least most at this point, and just the build quality and way the cases are made, big fan. Would like to get the P600 next.

    from completed build Cyberpunk Rig

    Absolutely love this case. Incredible ease of installation with nice velcro straps on the back panel. The RGB controller can be utilized but I opted to have the front fan RGB controlled by my motherboard. Unfortunately if you get this version, you lose the 4 prong for the fan power itself. This means that you can't control the speed of the fans based on CPU temp/voltage out of the box. There may be a way to add a controller to the system but I didn't wanna get that intense. So my front intake fans run at 1200 RPM at all times which is a little bit of a bummer but its honestly not very loud so NBD.

    Really happy with my case. Lot of place to work on, cable management is really easy even if I hate it alot.

    Case is sturdy, look good, fan are quiet, 10/10. Can't buy better for the price I think
