Mehak Sohail | Last Updated On November 22nd, 2021

Let’s face it, loud PC’s are obnoxious for both the user and the other people in the room.

Whether you’re fully immersed in a game or concentrating hard on your work, a loud PC can instantly ruin your focus.

For this reason, the Phanteks Eclipse P600S is the overall best quiet PC case and runs extremely silently no matter what you’re doing. The Pure Base 500DX is the best budget-friendly silent PC case and offers the best bang for your buck.

In today’s in-depth guide, I’ll walk through the top 10 silent PC cases you can buy today (also see here if you want to check out for open air PC cases). Whether you’re looking for a full-tower, mid-tower, or micro-tower I’ll cover everything you need to know.

Let’s get started.

PC Case Buying Guide

Before picking the right silent PC case, there’s a few things you need to keep in mind. Let’s discuss these now.

Chassis (Case) Size:

The most important factor when choosing your PC case size is your motherboard and GPU sizes. Silent PC cases come in three sizes: Full-tower, Mid-tower, and Mini-tower.

Mid-tower cases are the most prevalent since they allow for efficient cooling but aren’t too big. However, the size of your case is mostly up to your preference and how much cooling and sound dampening capability you want.

Make sure to keep the sizes of your motherboard and GPU in mind as you’re choosing a new PC case.

Case Design and Aesthetics:

Most PC users don’t consider what their cases look like, but for PC enthusiasts like us, design is highly important. However, silent PC cases don’t often come with elegant designs. This is because they are designed for silence and not aesthetic.

Nevertheless, there are a few quiet PC cases that are both silent and beautiful that’ll I’ll discuss below.

Cooling:

Modern day PC’s require efficient and effective cooling. Choosing a case with weak thermals can cause your computer to overheat. The amount of cooling your PC needs depends on how much load you’re putting it under and what components you’re loading the computer with.

Look for quiet PC cases with a good airflow scheme and lots of fan slots. Since silent PC cases tend to have less airflow, I’ll show you all the best options available.

Accessibility:

The last thing you should consider is how accessible the interior components of your PC are. If the PC case is hard to build in, I’d recommend looking for a more beginner friendly option.

The Best Quiet PC Case

If you’re looking for the best overall PC case that stays silent, looks amazing, and boosts the performance of your build, then the Phanteks Eclipse P600S is exactly what you need.

High Level Summary

This delightful case comes with a powder coated steel frame, optional tempered glass panel, and the best sound dampening technology you can find.

Furthermore, this case offers the ability to easily switch from silent mode to performance mode, is reasonably priced, and uses a layout designed to support any build.

Since you’re looking for a quiet PC case, the most important feature is the sound dampening technology. Luckily for you, the Phanteks Eclipse P600S delivers unbelievable silence.

The side panels on the case are insulated and designed to cancel most of the high and low-frequencies before they exit the build. With three high-quality layers of sound deadening insulation, even the loudest components in your PC will be hard to hear. Furthermore, your PC will still run cool despite being in silent mode because of the airflow integration in the case.

Another great feature about this case is that it comes with three pre-installed fans. These fans are built to be silent with low rpm and will keep your PC nice and cool along with the four other fan slots.

For the overclockers and heavy duty PC enthusiasts, let’s talk about the performance mode. While silent mode keeps your PC unbelievably silent, how does performance mode shape up in terms of sound and heat?

The side panels on this case are able to swing open and the front and top panels can come off to show high-airflow promoting fabric mesh. This provides even more airflow when you’re putting your PC under load. The Phantek Eclipse P600S fires on all cylinders regardless of how much performance you need.

Other features include excellent cable management with the included Velcro ties, four SSD mounts, a massive PSU compartment, and a tool-less design to promote easy building.

Color options include Satin Black, Anthracite Grey, and Glacier White. If you’re looking for the best overall quiet PC, look no further, the Phanetek is top-of-the-line.

The first thing you’ll notice about the Pure Base 500DX is the vibrant and inviting RGB lights. Along with a beautiful display, this case also offers premium sound dampening features, amazing airflow, and a great price point.

High Level Summary

The Pure Base 500DX uses side panel insulation mats on the tempered glass along with a steel build. This allows the majority of sound waves to be canceled before they even leave the case.

This case also comes equipped with anti-vibration decoupled mounts for the HDD slots and PSU. So, the components in your PC that may get noisy as they’re moving around will actually become completely mute because of the vibration cancelling technology.

While the silencing features stand out, the best quality of this case is its ability to ventilate airflow. With high airflow front and top panels, this case ensures great intake and exhaust.

Furthermore, the Pure Base comes with three 140mm fans preinstalled. They’re located on the back, front, and top of the machine to provide excellent silent airflow.

Even though there’s no performance or silent mode, you’ll be getting great airflow and silence at all times.

Other features include a dedicated PSU shroud to place the PSU and hide the cables, six included Velcro ties, preinstalled ARGB lights on the front and inside, and a three year warranty.

However, let’s talk about a few of the common challenges users have with this case.

Firstly, the instruction manual can be difficult to understand as you’re setting up the case and installing your components.

Furthermore, there’s no padding for the HDD and PSU mounts so if a component becomes loose and shakes around, it may emit some noise.

Color options include either black or white and the option for a tempered glass or fully steel side panel.

The Fractal Design Define C is a case that offers industrial grade sound dampening technology, amazing airflow capabilities, and a stealthy design.

Check Latest Price

High Level Summary

Using Fractal Design’s patented ModuVent technology, this case is able to provide efficient airflow while keeping sound to a mute.

Furthermore, the ModuVent technology allows you to choose if you want a standard full-plate side panel or ventilated panel.

The side panels are easy to adjust and are lined with industrial grade sound dampening foam, seven fan slots, and two pre-installed 140mm fans.

If the ModuVents are in full-panel mode, airflow is slightly affected but not enough to overheat your computer. If in ventilation mode, the top vent has an optional filter that can be placed in to provide high efficiency airflow.

The PSU shroud compartment and Velcro straps help you keep your PC build nice and organized. Moreover, the Define C is extremely spacious.

This case only comes in black and has the option of a full-tempered glass side panel, smaller windowed side panel, or full steel.

If you’re looking for a case that isn’t too flash and gets the job done well, the Fractal Design Define C is a perfect choice.

A great silent case for all PC enthusiasts is the Silent Base 601. This case offers extremely high quality sound dampening features and is super easy to build in. However, the overall ventilation and airflow leave a tiny bit to be desired.

Check Latest Price

High Level Summary

Similar to the Pure Base 500DX, this case also uses sound dampening mats with high quality foam on the front, top, and side panels.

If you choose the variant without a tempered glass window, you’ll get a little bit of extra noise reduction which isn’t totally necessary.

This silent case also features unique noise dampening vents that provide another layer of sound dampening while still permitting airflow. If you’re overclocking your system, all you’ll hear is a tiny little whisper, making the Silent Base 601 an amazing choice for a silent PC case.

Let’s talk about the ventilation and cooling issues I discussed earlier. Basically, the top and front panels provide limited ventilation. Even with seven fan slots and two included fans, higher heat builds can potentially be met with issues.

The Silent Base 601 also offers an exceedingly simple build design and cable management. Beginners can rejoice as the manual is easy to comprehend and follow.

Color options include orange, black, silver accents.

If you’re new to PC building or just looking for a standout case that isn’t too pricey, the 601 is a great choice.

If you’ve dabbled a bit in PC building and want something more unique, the Cooler Master Mastercase SL600M is just the right option. Although it’s slightly more expensive than other cases on the list, the Cooler Master offers “cool” features that are worth the price.

Check Latest Price

High Level Summary

The massive low rpm fans and vertical chimney design offer impressive airflow. This case is also ridiculously silent and is equipped with a rotatable PCI bracket plate.

However, beginners should be aware that this case can be complex to build in. Since the PSU shroud is located at the front of the case, it can be difficult to manage all of your cables since they will naturally want to hang down.

Let’s talk more about the features. Two massive 200mm pre-installed fans spin at a low rpm to keep the case cool and quiet. Furthermore, this case is built with anodized aluminum, tempered glass, and a steel frame.

As I said early, this case is built with a vertical chimney-based design. Most standard PC cases have ventilation that runs from front to back. The Mastercase utilizes the natural rise of heat to aid in ventilation.

This case also includes lots of USB ports, an adjustable fan slide, and a motion sensor for USB LED indicators.

Overall, the Cooler Master Mastercase SL 600M is a premium quiet PC case that’s aesthetically pleasing and highly functional.

Specs

  • Form Factor: Mid-tower
  • Motherboard Support: ATX, Micro-ATX, mini-ITX

The Dark Base Pro 900 Rev. 2 silent PC case offers a high level of customizability and soundless efficiency.

Check Latest Price

High Level Summary

The Dark Base Pro 600 Rev. 2 is another premium case that costs more because it has more features.

However, it does have weaker thermal performance than other cases and requires additional coolers if you’re running a high-duty rig.

Nevertheless, this case does do an amazing job at keeping things silent. It does this by using solid paneling and a mostly closed design. The aluminum, steel, and tempered glass paired with the panel insulation mats allow for a uber quiet experience.

The Pro 900 features anti-vibration technology in the HDD, PSU, fans and motherboard slot which cancel out all shaking sounds. When it comes to silence, this case is as good as it gets.

You have the option of removing the front panel on the case to reveal a mesh layer with additional ventilation. Furthermore, there are three preinstalled 140mm fans that are silent and offer efficient airflow.

This case can support up to seven fans and a variety of air and water coolers. On top of that, the best feature about this case is its size and versatility. Using a modular design, this case can support multiple HDDs, SSDs, and optical drives.

Specs

  • Form Factor: Full-tower
  • Motherboard Support: E-ATX, XL-ATX, ATX, Micro-ATX, mini-ITX
  • Dimensions: 243 x 586 x 577mm

The Corsair Carbide Series 275 is the most practical quiet PC case that’s also very affordable. If you’re on the hunt for a simple PC case that efficiently lowers sound and cools your rig, the search is over.

Check Latest Price

High Level Summary

This is a fully steel paneled case without any windows to glance inside, meaning there’s no need for cable management. The Corsair is the ultimate case for simple and beginner builds.

With a fully steel case, there’s nowhere for the noise to escape. The all-steel panels also include sound dampening foam that insulates sound waves. The only holes on this case are in the form of small ventilation slits along the front of the case.

With an almost fully-sealed design, ventilation can become a challenge. The case comes with two pre-installed fans and can hold up to six. Furthermore, the top panel is removable for better ventilation but the sound dampening features are also removed.

Overall, the Corsair is a great minimalist case that provides excellent silencing capabilities and is a great choice for beginners.

  • Motherboard Support: ATX, Micro-ATX, mini-ITX

If you’re looking for a budget friendly micro-tower case with amazing sound dampening, the Cooler Master Silencio S400 is the best pick.

Check Latest Price

High Level Summary

Coming only in black, this case has the option of including a tempered glass window. Behind each panel are sound dampening foam insulators that efficiently soak up sound waves and vibrations.

Although you can easily purchase a more functional and aesthetic case with a few more dollars, the Silencio S400 is clean and compact.

Since this case is almost fully sealed, the increase in silence is accompanied with a lack of ventilation. With a sealed front door and top panel in place, there are only a few slits that provide ventilation.

However, the case does include two pre-installed fans and has space for more throughout. But based on my experience, the case runs very hot when all the panels are in place.

Overall, this quiet PC case is a compact workhorse that is best suited for lower performance rigs.

Specs

  • Form Factor: Micro Tower
  • Motherboard Support: Micro-ATX, mini-ITX
  • Dimensions: 210 x 408 x 418mm
  • Weight: 15.5lb / 7kg
  • Radiator Support: 120mm, 140mm, 240mm, 280mm
  • I/O Ports: 2x USB 3.2 Gen 1, 1x HD Audio/Mic, 1x SD card reader

The ABOKCORE S500 is a low to mid budget silent PC case that provides great versatility and a simple aesthetic. 

Check Latest Price

High Level Summary

This case is built with steel, plastic, and also features sound dampening foam on each side of the body.

However, just like the Silencio S400, this case sacrifices ventilation for more silence. None of the panels are removable or able to be opened. For this reason, this case relies on the two pre-installed fans and one additional fan slot to cool the PC. For a full sized tower, there’s an extreme lack of cooling capabilities.

The best feature of this case is the ability to support up to six SSDs.

Overall, the ABKONCORE S500 is on the lower end of the best quiet PC cases and great for users who don’t run high level rigs.

Specs

  • Form Factor: Mid-tower
  • Motherboard Support: ATX, Micro-ATX, mini-ITX
  • Dimensions: 205 x 420 x 430mm
  • Weight: 15.4lb / 7kg

The front and side panels are equipped with sound dampening insulation. Furthermore the steel build and anti-vibration padding on the SSD mounts provide an extremely silent build.

Furthermore, you’ll need to be more selective with the components you use since the case is smaller in size.
