4000 & 5000 Series Case Comparison

Corsair CJ

Our 4000 Series and the most recently launched 5000 Series cases have arrived! Both lineups signal a return to classic CORSAIR styling with a focus on improving the build experience, flexibility, and performance over our previous lineup of cases.


This new case lineup began with the 4000 Series launching back in September of 2020, introducing features like the RapidRoute cable management system, more space behind the motherboard tray, and all new case fans developed with CORSAIR AirGuide technology for delivering focused airflow to your components, all of which come together to make it simple and easy to make a clean looking and high performing build.

CORSAIR AirGuide technology utilizes stator vanes built into the frame of the fan to concentrate airflow out the rear of the fan.

The 4000 Series is a great starting point, but if you need even more room for massive cooling such as a custom water cooling loop built with Hydro X components, our most recently launched 5000 Series of cases take those great features introduced by the 4000 Series and expands on them with more cable management features using the CORSAIR RapidRoute cable management system and more options for mounting cooling hardware, all packed in a mid-tower chassis that’s grown in every dimension.

Since it might be a little difficult to tell the size difference between the two case series, we’ve put together some line art with examples of both cases side by side to illustrate:

It’s clear that the 5000 series case lineup expands on many of the same features present in the 4000 series, the most noticeable difference being in size and the addition of fan/radiator mounting on the motherboard tray as an option.

The 5000 series’ expanded mounting options allow for increased flexibility and headroom should you decide to water cool your system with CORSAIR HYDRO X Series components or if you decide to do a build with a large graphics card like the RTX 3090 or RX 6900 XT which seems to be the current trend in gaming builds.

The 4000 series, being the sort of little brother in our case lineup, you can still build a high end water-cooled system in a 4000 series case as shown by expert builder Hans Peder Sahl so if you’re up for the challenge or maybe just want a smaller footprint, the 4000 series cases are a great option for your next build!

It’s an exciting time to be a builder and both our 4000 series and 5000 series cases are ready for anything, be it a simple office workstation, a new gaming rig, or a top-of-the-line water-cooled monster.
