    Very good case. It has terrific airflow and is pretty good looking. It does look bulkier in person than in the photos, but I appreciate the size because this was my first time building a PC, so it was nice not to be working in a crowded case. Also a very fair price.

    I bought this case for a teenager's first desktop. It's a pretty well-made case with good airflow. Most cables are routed cleanly on the underside of the motherboard. I didn't have any problems plugging in an older power supply and getting the cables to route. It has good airflow, top-side ports for usb/usb-c, and has a clear side panel if you're into blinky lights and rainbows. The only negatives I had were (1) the case is wider than what I thought it would be from the pictures and (2) there aren't any external-facing drive bays.

    This is a really good case, i love how i can access my fans to be able to clean them without having to disassemble half the case and it has a lot of room in it to basically put anything you need in it.

    Good case, for a great price. I got it on sale. Made for a great upgrade over the previous case. Though it can be on the small side if you need more fans for more cooling. Can be a beast for cable management if you have a lot of fans that require wiring.

    A high quality, beautiful computer case. It includes 2 fans for cross flow. Design is well laid out to install all components and provides several cable management features. The smoke glass panel on the side shows off motherboard LEDs.

    I love this case, plenty of space to build in and easy cable management. Note that if you plan on using one or more radiators, there is a more expensive model that also has room for fans on the side that you should consider.

    Built a new PC in this case a few months ago. There is a lot of space behind where you mount the MB to route your cables. Many convenient and good looking holes to hide cables.

    Solid case, good airflow, easy cable management, and looks super nice. RGB shines through the case and when turned off, the glass hides most of the internal components.

    Awesome case, plenty of vents and room for cable discipline. I like the floor legs that are higher than normal case, allows for additional ventilation. Even more room for additional fans if you like. We got them for 3 people and everyone loves it. Highly recommended.

    Excellent case. Airflow is incredible. Keeps my 3080 super cool. The build process was very straightforward. Relatively easy cable management. Only qualms are that the tint on the glass is a little dark and the plastic corners look not refine.

    Awesome Case

    Excellent case for the price! I was impressed with the amount of features that come standard with the Corsair 400D. The snap on mesh front, and magnetic mesh top screen are features that not many other cases offer in the sub $100 category. Thermals are good as you would expect for a case with this much mesh. The case stands off the ground a good bit and should be fine if it had to sit on a low carpet. After working with a few other brands of entry level cases, I'm a believer that the built in cable management on this case is some of the best in the industry. The side panel is tinted glass and makes RGB lighting less blinding. My only gripe with the case is the included two HDD/SSD case is intended to be mounted next to the PSU, and the location of the holes makes it a bit challenging to cable manage with a modular PSU. Overall, this case looks fantastic, and has exceptional features for the price

    Moving from an Omen 30L. Lots of space, lots of places for cables and expansion. Nice, clean look. I like the magnetic dustmat and the option to mount SSD on the rack in front of the mobo.

    Bought two of these as my friend and I were building together and the cases have performed extremely well. As long as you have a good fan set up, airflow will passthrough and keep your system cool. It comes with cable management lane in the back along with straps.

    [Employee of bestbuy] This and the 5000D aren't the flashiest cases, but they are great for cooling, have all the ports you want, and are great for cable management
