Best Looking Open Air Case

Cougar Conquer 2 - Best Looking Open Air Case
Cougar Conquer 2

Type: Full Tower | Colors: Black | Motherboard Support: Mini-ITX, Micro-ATX, ATX, CEB | Dimensions (WxHxD): 368 x 631 x 744 mm | GPU Clearance: 400 mm | CPU Cooler Clearance: 150 mm | PSU Clearance: 220 mm | Expansion Slots: 10 | Included Fans: 1x 120mm fan | RGB: Yes

Pros

  • Extraordinary design
  • Great airflow and thermals
  • Integrated RGB lighting
  • Detachable sub-chassis feature

Cons

  • Expensive
  • Prone to dust

Cougar is known for taking risks and thinking out of the box in the PC case market, and the Conquer 2 is a continuation of that trend. The Conquer 2 takes a page from the original Conquer case and takes everything to the next level. 

Design: One simply cannot talk about the Cougar Conquer 2 without diving deep into its design. The Conquer 2 is one of the most unorthodox cases out there, as it combines an open-air chassis design with a traditional box style. The Conquer 2 is a full-tower case that supports all the common motherboard form factors and has ample space for any modern GPU or CPU cooler. Its unique style has been labeled as a “helicopter design” by many enthusiasts.

Cooling Performance: Despite its unusual appearance, the Conquer 2 does not sacrifice the essentials. Cougar has taken great care to incorporate massive air channels on the front and sides of the case to maximize its cooling performance. The Conquer 2 can support radiators up to 360mm AiOs, and fans up to 120mm on 6 separate slots. The open-air design of the Conquer 2 allows it to maximize air intake from the front and sides, which is why it is a great choice for all kinds of CPU and GPU cooling.

Build Quality: Once again, the Conquer 2 justifies its premium nature with extraordinary build quality. Cougar has used solid sheet metal for the outside shell as well as the inside chassis of the Conquer 2, with minimal flex and high structural rigidity. On top of that, the Conquer 2 comes with 4 tempered glass side panels, which only enhances its build quality. Finally, the inside chassis of the Conquer 2 is detachable, which is a superb convenience feature.

Aesthetics: The Conquer 2 excels in the aesthetics department, as it takes the risk of deviating from the traditional boxy design of PC cases. The case looks more or less like a helicopter cockpit, and Cougar’s branding very much supports this theme. The Conquer 2 looks superb when it is filled with components, particularly when the design is enriched with custom RGB components or water cooling. Cougar also provides one pre-installed 120mm RGB fan on the front to complement the fantastic Trelux integrated RGB lighting at the front of the case.

Noise Level: Being an open-air case, the Cougar Conquer 2 performs admirably when it comes to the acoustics. It is definitely a bit louder than you would expect from a traditional box-style case, but that is to be expected due to the open-air nature of its chassis. The Conquer 2, however, has better airflow than most closed cases, which means that you will not have to install as many fans in the Conquer 2 to keep the internal components at a reasonable temperature.

Value For Money: As a case with a unique shape and innovative design language, it makes sense that the Cougar Conquer 2 is priced at the premium end of the market. However, that is understandable since the tooling and production costs of the Conquer are higher than regular cases. The value proposition is still generally positive as the Conquer 2 holds a unique position in the market that is not challenged by any mainstream competitors.

Buy It If:

You want a case with exceptional design: Featuring a completely unorthodox “helicopter” style exterior and an open-air design, the Cougar Conquer 2 will definitely draw attention to your build.

You want integrated RGB lighting: While case RGB lighting is not rare, the Cougar Conquer 2 is one of the few open-air cases to feature integrated lighting.

Don’t Buy It If:

You have a limited budget: Although the Conquer 2 holds a unique position in the case market, it can certainly deplete your savings.

What Makes It The Best-Looking Open-Air Case?

Featuring an extraordinary exterior design, superb airflow, RGB lighting, and premium build quality, the Cougar Conquer 2 is the best-looking open-air case.

Thermaltake AH T200

Best Open Air Case For Under $100

Thermaltake AH T200 - Best Open Air Case For Under $100
Thermaltake AH T200

Type: Mini Tower | Colors: Black, White, Pink | Motherboard Support: Mini-ITX, Micro-ATX | Dimensions (WxHxD): 282 x 444.2 x 551.5 mm | GPU Clearance: 320 mm | CPU Cooler Clearance: 150 mm | PSU Clearance: 180 mm | Expansion Slots: 5 | Included Fans: None | RGB: No

Pros

  • Unique helicopter design
  • Various color choices
  • Great for compact builds
  • Relatively affordable

Cons

  • Limited motherboard compatibility
  • No included fans

It seems like there is a recent surge in demand for “helicopter” style cases, as the Thermaltake AH T200 is another example of this popular trend. I am not complaining, however, as the case looks absolutely fantastic and is also relatively affordable.

Design: Thermaltake has always been courageous with its designs, and the AH T200 is a continuation of that trend. The AH T200 fits in the mini-tower case category, as it supports only micro ATX and mini ITX motherboards. This makes it a fantastic choice for enthusiasts looking to craft a compact gaming build in a mATX open-air case, but it also limits mainstream motherboard compatibility. Of course, the AH T200 also incorporates an open-air style chassis that separates it from the crowd and maximizes its GPU and CPU cooler compatibility.

Cooling Performance: In its stock configuration, the Thermaltake AH T200 is an above-average performer in terms of thermals. The open-air design of the chassis allows plenty of air to flow through the cabin without much restriction, which is ideal for tower-style CPU coolers. However, Thermaltake does not provide a pre-installed fan in the case. Since the case is relatively affordable, you can spring for the best 120mm open-air case fan to fill one of the four 120/140 mm fan slots available.

Build Quality: The AH T200 from Thermaltake truly excels when it comes to build quality. It features a solid steel frame with 5mm thick tempered glass panels on each side, with 3mm thick tempered glass windows at the front. Both the side panels feature a double-hinged design for maximum convenience and a premium feel. The case features a dismantlable modular design with detachable panels, racks, brackets, and much more, allowing the user to customize the look of the case while increasing convenience as well.

Aesthetics: The design of the Thermaltake AH T200 truly elevates it above the plethora of boxy cases available on the market. Its unique “helicopter” design stands out immediately even from the far end of the room. Thermaltake also offers the AH T200 in an all-white or pink color scheme. I particularly like the white PC case as it would go well in our all-white PC build. The case lacks any built-in RGB lighting but you can always fix that with an aftermarket RGB strip or fan pack. The dual-tempered glass side panels also add to the personality of the case and your setup.

Noise Level: By design, the Thermaltake AH T200 has been crafted to be a quiet case. It is a compact chassis with an open-air design that maximizes airflow from all sides. It features huge vents on the front and the sides for laminar and smooth airflow patterns. Although it may be slightly louder than competing full-sized open-air cases, it still maintains a comfortable acoustic profile at stock, without having an adverse effect on temperatures. You can even add an aftermarket fan without observing a noticeable change in the noise profile.

Value For Money: One does not usually relate such unorthodox cases with affordability, but that is exactly where the Thermaltake AH T200 shines. Despite its unique design and superb build quality, the T200 is a relatively affordable case and delivers excellent value for money. There are not a lot of open-air cases available in this price bracket, let alone those that look as nice as the AH T200. If you are in the market for a compact, micro-ATX budget PC case with an open-air design, this is the one to get.

Buy It If:

Thermaltake AH T200

You want an affordable open-air case: At just under $100 at the time of writing, the Thermaltake AH T200 delivers superb value for money.

You want a compact open-air case: If you’re looking for a small form factor case with a unique design, the Thermaltake AH T200 is the way to go.

Don’t Buy It If:

You want a bigger case: The AH T200 is a micro-ATX case, so it has limited compatibility with standard motherboards, PSUs, GPUs, and CPU coolers.

What Makes It The Best Open-Air Case For Under $100?

Thanks to its unparalleled aesthetics, impressive acoustics, and exceptional value for money, the Thermaltake AH T200 is the best open-air case under $100.

  • Ideal for water-cooling
  • Excellent airflow

Cons

  • Quite pricey
  • Dust prone

We are back with another unique open-air chassis from good ol’ Thermaltake, which has become a household name when it comes to extraordinary PC cases. The Core P3 Pro is a fantastic example of form meets functionality, as it is one of the most attractive PC cases out there while being extraordinarily efficient.

Design: The Core P3 Pro is one of the larger cases on our list, but it still fits in the mid-tower category. It conforms with the traditional boxy standards of regular cases, but completely redesigns the shape by implementing an open-air style. The P3 Pro can support motherboards up to the E-ATX standard and can even support GPUs up to 450 mm in length, so compatibility is not really an issue with this chassis. Its unique design also allows it to be used in both a tower-style and desktop-style orientation.

Cooling Performance: One of the strongest features of the Thermaltake Core P3 Pro is its extraordinary cooling performance. Owing to its open-air design, the Core P3 does an excellent job dissipating the heat from the internal components and preventing heat buildup. The chassis can support radiators up to 420mm, with up to 6x 120/140mm fans, allowing you to maximize the cooling potential of its open-air style. The Core P3 Pro offers a detachable fan bracket that allows you to move the positioning of your fan slots as you please, allowing for numerous liquid cooling configurations.

Build Quality: Continuing the trend of premium Thermaltake cases, the Core P3 Pro delivers outstanding build quality and high-end materials. The case uses a rigid steel chassis with a large 4mm thick tempered glass panel on the front, giving it its unique look as well as structural rigidity. The motherboard tray is recessed and has high-quality cable grommets for easy and clutter-free cable installation. The case also features rotational PCIe slots for vertical or horizontal GPU installation, and the dismantlable modular design of the chassis allows you to customize your build according to your needs.

Aesthetics: Open-air PC cases have the potential to elevate the looks of your entire setup, and the Core P3 Pro is one such example. When fully configured with RGB components and custom water-cooling, the Thermaltake Core P3 Pro has the potential to look absolutely phenomenal from all angles. The case’s unique design allows it to be displayed in a wall-mounted configuration as well, which can provide a whole new look to your gaming setup. Although the case itself does not incorporate RGB lighting, the open design of the case is well-suited for displaying your finest components.

Noise Level: With an open chassis like the Core P3 Pro, you do expect a bit of a higher noise floor than a normal box-style case. The lack of a confined space allows the noise to be transmitted without significant hindrance, thus increasing the perception of noise. The Core P3 Pro falls in the same category, but its noise profile is better than average. Owing to its extraordinary airflow and versatile layout, the cooling fans do not have to ramp up as much to keep a comfortable internal temperature. Moreover, the case also does not trap heat due to its open nature, further lowering noise.

Value For Money: Compared to regular box-style cases, the Thermaltake Core P3 Pro can be found on the more premium side of the pricing spectrum. However, in the context of the open-air case market, the Core P3 Pro is actually priced quite reasonably and delivers a solid value for your money. With extraordinary features and superb airflow, the Core P3 Pro can outperform any competing box-style case in terms of thermals while having the upper hand in aesthetics and functionality. The Core P3 Pro further justifies its price tag with its unique features, such as the ability to be mounted on the wall, making it one of the best overall PC cases.

Type: Test Bench | Colors: Black, White, Orange, Red, Yellow, 8 Others | Motherboard Support: Mini-ITX, Micro-ATX, ATX, E-ATX | Dimensions (WxHxD): 483 x 440 x 461.8 mm | GPU Clearance: Open | CPU Cooler Clearance: Open | PSU Clearance: 300 mm | Expansion Slots: 6 | Included Fans: None | RGB: No

Pros

  • Versatile use cases
  • Various color options
  • Wide compatibility
  • No airflow restrictions

Cons

  • Expensive
  • Plain design

The test bench style has grown in popularity over the past few years, particularly among enthusiasts. The PrimoChill Praxis Wetbench provides a certain level of convenience and versatility that is just not possible with normal PC cases, therefore making it one of the more innovative open-air cases out there.

Design: PrimoChill has deviated a bit from the traditional flat test bench design by incorporating 2 different platforms, with the top one being at an angle. This allows the motherboard and adjacent components to take full advantage of the available space, which is why the Praxis Wetbench is compatible with all popular motherboard form factors. The case also shows unrestricted compatibility with GPUs and CPU air coolers since there is no side panel. The PSU compatibility is also generous, with an upper limit of 300mm for this particular test bench.

Cooling Performance: Since the PrimoChill Praxis Wetbench uses an open-air style with no restrictions to airflow, it delivers superb cooling performance in all possible scenarios. The case is also quite well-equipped for water cooling, as it has mounting points for a pump, reservoir, and radiators up to 360mm in length. The test bench has no restrictions on airflow, so it is ideally suited for both air cooling and water cooling, making it one of the most versatile, best airflow cases on the market right now.

Build Quality: One glance at the PrimoChill Praxis Wetbench will let you know that it is a premium piece of equipment. The craftsmanship and metalwork are absolutely top-notch, giving the case an air of supremacy. The case elevates the open-air design by incorporating a modular system with interchangeable parts, allowing you to customize your test bench according to your needs. The motherboard and radiator rack can be easily disconnected to completely change the layout of your build. The Wetbench is also fine-tuned for custom water cooling, further elevating its desirability.

Aesthetics: Cases in the test bench style are not really sought for their aesthetics, but that does not mean that you can’t build a nice-looking rig on such a case. The PrimoChill Praxis Wetbench offers a very wide array of color options that can help you personalize your test bench. You can get either a black or white base, with accents that can be configured in red, green, blue, yellow, purple, and many other colors. Although the case does not house any built-in RGB lighting strips, the unique color options do make up for the lack of personalization elements in a case that is primarily focused on functionality.

Noise Level: An open-air test bench will always have a slightly higher noise profile than an enclosed chassis, and the same trend can be seen in the PrimoChill Praxis Wetbench. However, when properly configured, the acoustic profile is very comfortable and does not raise any significant red flags. The fans of the GPU and CPU cooler do not have to ramp up aggressively, since the airflow is so good by design. Even in a custom water-cooling loop, the fans can be easily configured to hit the sweet spot between performance and acoustics. 

Value For Money: Due to its unique nature and narrow target market, the PrimoChill Praxis Wetbench is certainly a premium PC case. However, it is one of the most well-built and versatile test benches on the market right now. With extraordinary functionality and a host of customizable features, the Praxis Wetbench is one of the foremost recommendations for enthusiasts who are in the market for a high-end test bench.

Type: Mid Tower | Colors: Black | Motherboard Support: Mini-ITX, Micro-ATX, ATX | Dimensions (WxHxD): 470 x 470 x 615 mm | GPU Clearance: 320 mm | CPU Cooler Clearance: 180 mm | PSU Clearance: 220 mm | Expansion Slots: 8 | Included Fans: None | RGB: No

Pros

  • Dual-chamber design
  • Exceptional build quality
  • Impressive thermals and airflow
  • Great for custom water cooling

Cons

  • High price
  • Very large footprint

Continuing the trend of extraordinary case design and innovative layouts, Thermaltake brings forth the Core P90 which is crafted specifically with custom water cooling in mind. The case takes the open-air concept and turns it up a notch, allowing the user to fully express themselves through its unique design.

Design: Thermaltake has opted for a dual-chamber design with the Core P90, but not in the traditional sense. Instead of positioning the two chambers back to back, the Core P90 positions them alongside each other at an angle, creating a unique triangular look when observed from above. The Core P90 still conforms to the mid-tower case standard, so it has support for mini ITX, micro ATX, and regular ATX motherboards. Thanks to its exceptional layout, the Core P90 is the perfect wall-mounted open-air PC case as well, and it can be used in a regular tower-style or desktop layout too.

Cooling Performance: The Core P90 is an extraordinary case for custom water cooling, and that is evident from its innovative layout. The case features an open frame with plenty of space for your reservoir and pump, while the radiator support spans all the way up to 480mm. Moreover, you can also add 4x 120mm fans or 3x 140mm fans if you choose to go with regular case fans instead of a radiator. The airflow inside the chassis is fantastic, thanks to its open-air design and large ventilation gaps.

Build Quality: Thermaltake’s Core P90 also delivers superb build quality in all areas, thanks to high-quality materials and expert craftsmanship. Connected to the steel chassis, the two 5mm thick tempered glass panels provide a premium feel to the case. Moreover, the Core P90 features a modular system in which users can customize the components of their case by removing panels, racks, brackets, and so on. The case also allows you to install the GPU in either a horizontal or vertical mount, thanks to the inclusion of the TT Gaming PCIe 3.0 Riser Cable.

Aesthetics: Once the case is fully furnished with components, it is hard to look away from the masterpiece that is the Thermaltake Core P90. Especially when a custom water cooling loop is installed, the design of the chassis complements the internal components extremely. well. The angled tempered glass panels separate it from the traditional boxy design of boring cases, allowing the user to glance at their build in all its glory. The Core P90 works especially well with RGB components and colored liquid, thanks to its unique viewing angles. Mounting the Core P90 on the wall will certainly make it a centerpiece of your entire room.

Noise Level: Since the Thermaltake Core P90 is specialized for custom water cooling, it really does not raise any significant red flags when it comes to acoustics. The open-air chassis does allow more noise to be transmitted through the case, but the superb airflow allows the case to balance the noise by running the fans at a lower overall speed. Moreover, if you install a liquid cooling loop in the Core P90, it automatically becomes one of the quietest PC cases on the open-air market thanks to its excellent radiator placement and unrestricted airflow. 

Value For Money: Certainly, an innovative open-air chassis like the Core P90 falls towards the premium end of the pricing spectrum. However, that does not make it an unreasonable consideration for your next water cooling build. The Thermaltake Core P90 holds a unique position in the market as it provides a completely unorthodox design with unmatched features. Whether you want the best water cooling case in a showcase style, or you just want to build a wall-mounted PC as a centerpiece of your setup, the Thermaltake Core P90 is an excellent value for that initial investment.

Open Air Case vs. Closed Case

Open-air Case Closed Case
Better airflow Slightly better acoustics
Exceptional aesthetics More dust protection
Ideal for water-cooling Better durability

The choice between an open-air PC case and a closed case presents distinct advantages and drawbacks that cater to specific preferences and requirements.

Open-air PC cases, characterized by their exposed design with minimal panels or covers, offer several benefits. They excel in thermal management by allowing unrestricted airflow, resulting in lower component temperatures. On top of that, open-air cases have the potential to look visually stunning, especially when water-cooling components are installed. Moreover, open-air cases often make components more accessible for easy installation, upgrades, and maintenance. However, these cases have the downside of lacking dust filtration, leaving components more vulnerable to dust accumulation over time.

On the other hand, closed PC cases, with their enclosed structure featuring various panels, prioritize noise reduction and dust protection. The closed design minimizes noise leakage, creating a quieter computing environment. Additionally, integrated dust filters help keep internal components cleaner, reducing the need for frequent PC cleaning. A closed case also offers better overall durability and endurance than an open-air one. However, this design can sometimes lead to higher internal temperatures, especially if the case’s airflow design is not optimized. 

Open Air Case Pros and Cons

Open-air cases, with their distinct lack of solid side panels, offer a range of benefits that appeal to both PC enthusiasts and gamers. One of their standout advantages is the superb airflow they provide. Unhindered by obstructive panels, these cases allow unrestricted movement of air, resulting in improved cooling for components. Additionally, the unique design of open-air cases not only showcases the internal components but also aids in dissipating heat efficiently, contributing to overall system stability.

For those who prioritize aesthetics and customization, open-air cases offer a canvas for creative expression. The absence of traditional side panels provides an unobstructed view of intricate water cooling setups, RGB lighting configurations, and meticulously organized cable management. Moreover, these cases often feature easy access to components, simplifying the process of hardware upgrades or maintenance.

However, open-air cases do come with certain drawbacks. Due to their lack of panels, they tend to have a slightly higher noise floor compared to enclosed cases that can dampen sound. The unrestricted case airflow that aids cooling can also facilitate the movement of dust particles into the system, leading to potential accumulation and increased maintenance requirements. Additionally, the unique design and advanced features of open-air cases often lead to higher price points compared to more traditional cases.
