The Best PC Cases in 2021

PC cases come in many sizes and configurations. And the thing is, best PC cases for some aren’t even near the best for others. Some users love silent PC cases, others prefer maximum airflow. Some users want the biggest case they can get, others adore small-form-factor cases.

While it’s impossible to decide on the best PC case around, it’s possible to make a limited selection of best PC cases in different categories. Today, we picked the best among full-tower, mid-tower, Micro ATX, and Mini ITX cases. No matter your preferences you will find an excellent case, just for you. Let’s start.

  • Front I/O Panel Ports: 2xUSB Type C, 4xUSB 3.0, Headphone and Microphone Jacks

This behemoth of a case has all you need for your build. Hell, it can even host the biggest EATX gaming motherboard and one Mini ITX motherboard simultaneously so it has all you need both for your main and secondary rig!

This Super-Tower case is much larger than any regular full tower case (but we’ll still consider it a full tower). You’ll need lots of room for it. Remember that in case you want to get one of these. It is capable of hosting up to 18 fans or four 480mm radiators simultaneously. And it’s perfect for complex, custom water-cooling loops.

If you’re looking for a perfect RGB case, the CORSAIR OBSIDIAN 1000D is the one to get. It comes with a preinstalled RGB controller with enough space for lots of fans and RGB LED strips. Finally, if you’re a data hoarder, good news! This case has enough room for 6 2.5” SSDs and 5 3.5” HDDs.

In a case like this one, expect superb airflow. Design is also stunning. Lots of glass and great placement of storage trays, fan mounts, and other components. Overall, this is the best full tower case on the market.

  • Can Host Two Systems Simultaneously
  • Superb RGB Support
  • Wealth Of Storage Bays
  • Slick Design
  • Superb Airflow

  • Pricey

be quiet! Dark Base PRO 900 Black Rev. 2

The Best Silent Full Tower Case

be quiet dark base pro 900 black rev 2
  • Form Factor: Full Tower
  • Motherboard Support: EATX, ATX, mATX, Mini ITX
  • Front I/O Panel Ports: 1xUSB Type C, 3xUSB 3.0, Headphone and Audio Jacks
  • Drive Bays: 10×2.5”, 5×3.5”, 2×5.25”

be quiet! Dark Base PRO 900 Black Rev. 2 is another bulky case but this one is built for silence, not great airflow (good but not great). It comes with 3 silent fans and has support for up to 10 fans in total. Also, it can host multiple 420mm radiators for liquid cooling solutions. Design is great, with cool orange details and side glass panel.

The case features a modular design with a removable motherboard tray that can be taken out for easy board installation. Modular HDD slots allow users to add or remove them depending on their needs. The included fan controller supports up to 8 fans and has the silent option to remove the noise.

Silent philosophy reflects in well-guarded PSU shroud but the shroud also makes installing the PSU very complicated. On the other hand, airflow is pretty good for a silent case. But high airflow means higher fan RPM and relatively high noise, which diminishes silent design.

The case supports 5 3.5” HDDs, 10 2.5” SSDs, and it also has two 5.25” mounts. You also get a wireless smartphone charger on the top, which is pretty cool. Overall, be quiet! Dark Base PRO 900 Black Rev. 2 is an excellent silent case but it’s too expensive and features unnecessary complicated PSU mount.

  • Low Noise
  • Slick Design
  • Solid Airflow
  • Modular Design
  • Wireless Smartphone Charger
  • Complicated PSU Installation
  • Expensive
  • High Airflow Mode Means Noticeable Fan Noise

  • Front I/O Panel: 4 X USB 3.0, 1 X USB 3.1 TYPE-C, 1 X HD AUDIO
  • Drive Bays: 6×2.5”, 4×3.5” or 10×2.5”

The Lian Li O11 Dynamic XL is an amazing case that comes with superb, high airflow design. The open design of the chassis allows maximum airflow even with just a couple of case fans, with room for up to 10 fans. Next, the case is big enough to host up to three 360mm radiators. You can fit a complex custom loop powered by a chunky pump without issues.

The case comes with excellent RGB support. The front LED strip is tasteful and not in-your-face with its RGB effects. And you also have a nice RGB controller for the LED strip. When it comes to storage space you can install up to six 2.5” SSDs or four 3.5” HDDs, or you can simply install 10 SSDs. You have a couple of hot-swap HDD racks for easy mounting on the go.

PSU installation is simple because the case has plenty of space and superb cable management. There’s also plenty of room for any setup, be that large EATX board or a normal ATX system. Design is minimalistic but right on the money. Without unnecessary elements, with plenty of glass and unimposing but tasteful details. Overall, this is a near-perfect case without any major downside.

  • Excellent Design
  • Superb Airflow
  • Simple PSU Installation
  • Excellent RGB Support
  • Price
  • Size (Subjective)

  • Solid Design
  • Lots Of Room For Radiators

  • Complicated PSU Installation

How To Choose A PC Case

There’s a lot to consider when looking for a new PC case. Let’s talk about the most important things.

Picking The Right Size

There are three main PC case form factors. We have humongous full tower cases, which can host any motherboard along with multiple GPUs and a bunch of fans or multiple water-cooling radiators.

Mid-tower cases are mainstream. They aren’t huge but can host full-size boards (ATX) along with dual GPUs, multiple fans, and large radiators. Some mid-tower cases can host large, EATX motherboards, but that’s not a common feature.

Small form-factor cases include Mini Tower and Mini ITX cases. The first ones are made for MicroATX and Mini ITX motherboards and are between mid-tower and Mini ITX cases when it comes to size. Not big but not super small.

Finally, Mini ITX cases are perfect for HTPC and low-profile gaming builds. They support Mini-ITX motherboards and, in very rare cases, mATX boards. Also, their airflow usually isn’t the best. But they offer compact footprint. Mini ITX cases take much less space than any other form factor.

Going Silent

Most PC cases are built to provide high airflow. But there are also cases built for maximum silence. They use various methods to reduce the noise. Such as silent case fans, special padding that soaks the noise from HDDs and fans, soundproof metal covers, and more. Do note that many quiet cases provide solid airflow, just don’t expect superb results.

Think About Features You Need

After you decided about the size and whether you want a silent or a regular PC case, it’s time to look for specific features you need. First of all, every case that comes into consideration has to have tool-less design and solid cable management. That’s the basis of every quality case. Additional features include:

Drive Bays – decide how many drive bays you need for your storage devices. Even smaller cases can host a large number of hard drives and SSDs so smaller size doesn’t have to mean just a couple of drive bays.

And make sure you’re satisfied with the number of bays because you won’t be able to increase them in the future. Except by getting a new case.

Number Of Fans Supported – another important thing to look for. If you want a high airflow case, make sure it can house plenty of fans. Just remember that even two fans can be enough for a solid airflow.

Radiator Mounts And Water Cooling Support – water cooling is more popular than ever so many cases support radiators for AIO liquid cooling systems.

Mid-tower and smaller cases usually support up to 280mm radiators. Some mid-tower cases have enough room for 360mm radiators.

When it comes to pumps and custom loops, look out for that. Some cases may come with space for one or two radiators but they won’t have enough room for a proper pump.

Dust Filters – another interesting feature that seems unimportant but can come handy. Cases with multiple dust filters make cleaning inside of the case much easier. All you have to do is to remove the filters and suck the accrued dust with a vacuum cleaner.

Cut-Out On The Back Of The Motherboard Tray – if you’re into custom air coolers for your CPU you might look for the CPU cutout at the back of the motherboard tray. The cutout allows users to replace the cooler without removing the motherboard, which can make the process much simpler and faster.

Space For The CPU Cooler – if you like huge air coolers for your PC, make sure the case you want has enough room for your cooler. There are some huge coolers that even full-tower cases cannot house.

Space For Graphics Card – last but not least, always check that the case you’re interested in is long enough for your graphics card. This is a small oversight that can completely ruin your setup. Each PC case lists max graphics card length in its official spec sheet. Do not forget to check that before buying a case.

Carrying Handle – there are great PC cases out there that feature a carrying handle. If you’re moving your rig often, think about getting a case with a handle attached.

Don’t Forget About The Front I/O Panel – The front I/O panel is the last thing many users look for in a PC case, but it can be important. For instance, if you have a VR headset a front placed HDMI port along with multiple (more than 2) USB 3 ports is a godsend.

Also, if you have a bunch of chargers and other USB accessories hooked up to your PC all the time, it’s handy to be able to hook them all to the front of the case.
