LianLi O11 Dynamic XL

The Lian Li O11 Dynamic is distinguished from the other products on the market by the use of seamless tempered glass for both the front and sides of the device. As a result of the O11 Dynamic not having a necessity for airflow from the front, this style is perfect for it. In terms of airflow, this enclosure supports a broad range of different fan configurations and directions, which allows it to satisfy the cooling requirements of even the most powerful components.

In this scenario, there are two key locations where intake fans might be put to beneficial use. The O11 Dynamic XL features slots on the bottom and the right side of the motherboard tray for the installation of cooling fans. Attaching the water-cooling radiators, each of which is capable of simultaneously supporting up to three 120mm fans, can also be done in these places if desired.

Radiators with diameters ranging from 120mm to 360mm may be placed in any one of the three available slots in the housing for these components. A 360mm radiator is more than enough for most general consumers, so we see the radiator support of this case as adequate. Even our selection of the best CPU coolers for i9 13900K tops out at 360mm.

Tubes leading to the heat-generating components can be routed along the length of the computer case from a water cooling distribution block installed to the right of the motherboard tray. This method not only produces an attractive and well-organized water-cooling loop but also aids in enhancing the build’s visual appeal.

You won’t be let down if you go with the Lian Li O11 Dynamic XL as your water-cooling solution of choice.

How we picked and tested

Picking the ideal PC case is already a complex task even before you add water cooling into the mix. Even the tiniest miscalculation can lead to compatibility issues and you may even need to reconstruct the entire build in a different case.

This is why we laid down stringent criteria when selecting the cases for this roundup.

Our primary focus was on the size of the PC cases we selected. Custom loop water cooling requires a lot of space, and it can even be helpful to have additional room to expand further down the line. This is why we selected large full-tower and super-tower cases in our roundup.

Secondly, we selected the cases that offered the best compatibility for water cooling components on the market. This includes space for reservoirs, custom tubing, large radiators, multiple fans, and other accessories. Any bonus water cooling features offered by cases were also considered in the final ranking.

Moreover, the aesthetics of the cases were also a major point of focus during the selection process of the different cases on this list. Custom loop water cooling can elevate the looks of your build to another level, and the case plays a huge part in that. Therefore, the design and lighting features of the cases were carefully considered.

We also laid a focus on the miscellaneous quality-of-life factors that can make or break a case. For example, the weight and build quality of a case are some of the factors we evaluated closely in this process.

Of course, we also considered the price and value proposition of the various cases that were shortlisted. While most water cooling cases are generally expensive, we prioritized cases that offered a better bang for the buck when it comes to water cooling features and compatibility.

In the testing process, our team of specialized hardware experts left no stone unturned. We carefully evaluated each selected case by running them through a gauntlet of tests specifically designed to test airflow and thermal performance.

Water cooling is directly dependent on the airflow of the case as the air is used to cool down the radiators, which is why thermal testing is crucial in this regard. The empirical and objective data obtained from these tests helped us greatly in the creation of this roundup.

This gave the editorial team a great idea of the quality of the different cases and the thermal performance that can be expected from them.

Combining the testing data with the objective analysis of the cases’ features and prices, we have curated a selection of the best water cooling cases you can buy for your next build.

AiO Liquid Coolers vs. Custom Loop

When deciding between an AiO liquid cooler vs. custom liquid cooling loop, you may be considering which option offers the greater value. The operation of both of these liquid-based cooling methods is similar but has some fundamental differences as well.

It should be made clear that AIO liquid cooling and custom loops are both viable methods of cooling, with many factors tipping the scales in favor of the custom loop and many others suggesting that AIO liquid cooling is superior.

From a true enthusiast’s point of view, a bespoke loop liquid cooling system is far superior to an all-in-one (AIO) liquid cooling solution. With a personalized loop, you can enhance both performance and aesthetics.

Subsequently, if you have an enthusiast-level motherboard with built-in VRM water cooling, you may benefit from a custom water cooling solution even more. The custom loop can be inserted into the pre-installed water-cooling heatsink to achieve better temperatures of the VRM. This can improve the performance and stability of the VRM in the long term.

One also has to take into account the advantage of custom liquid cooling loops in terms of aesthetics. You can design an extraordinary PC build with the use of appropriate hardline tubing, beautiful water blocks, and unique coolant. Using a custom loop can really elevate the looks of your PC build.

This is not to say that the AiO liquid coolers are not viable options, though. Since the temperature gain is not actually proportional to the higher cost, you should definitely stick with AiO coolers if you do not have an infinite budget for your build. All-in-one liquid coolers hold a massive advantage over custom loops since the latter is so much more expensive by comparison.

Also, ordinary AiO coolers are better suited for use in a regular PC build since custom liquid cooling loops require constant attention and maintenance. Consider these factors when you weigh the benefits of upgrading to custom loop liquid cooling against conventional closed-loop cooling for your next build.

How to Optimize your Airflow

When building your own PC, one of the most important things you should do is work on improving the circulation of air within the computer’s chassis. This approach should not just be tried by enthusiasts, but also by regular users on a more casual basis. This can keep the components of your computer from overheating, prevent the chassis from suffering exponential dust buildup, and, in general, improve the components’ expected lifespan.

In the first step, we are going to work on building up positive pressure inside the chassis. When we talk about positive airflow, what we mean is that the fans located inside of your system are taking in more fresh air than they are pushing out of the system in the form of hot air. Due to this, a positive cooling cycle is produced, which is exactly what you want to achieve.

When there is more air being flushed out than there is being drawn in, negative air pressure develops. This creates a potential vacuum that may start sucking air from cracks and crevices in the chassis, which results in an enormous amount of dust accumulation. The intake and expulsion cycles are balanced in a system with equal air pressure.

Moreover, placing the system in a cooler environment will allow for cooler air to be pulled in, which will reduce the temperatures of both your CPU and your graphics card (GPU). Fans, which are the primary operators in this entire cycle, have the potential to be the ultimate game-changers in successfully circulating the air depending on their size, speed, alignment, and type.

Radiators, if placed appropriately, may function as effective exhausts. In addition to ensuring that your system cools properly and that its circulation is not disrupted by unwanted foreign bodies, keeping your system clean on a regular basis and taking preventative efforts to keep dust and other particles that might cause blockages out of your setup are two of the most important things you can do.

Last but not least, if your chassis is still becoming too hot, you should consider looking at our recommendations for the best airflow PC case alternatives currently available and replacing it if necessary. It’s possible that our in-depth PC case buying guide will come in handy here.

Buyer’s Guide

Water cooling can be a tricky process, especially due to the various compatibility issues that can arise thanks to its bespoke nature. On the flip side, it is one of the most interesting and fascinating features you can implement in your custom rig.

Therefore, it is more than crucial that you buy one of the best water cooling cases if you want your build to go smoothly. Keep in mind the following factors when shopping for your PC case.


In cases that are designated for water cooling, space is of the utmost significance. The cooling system will consist of components such as the pump and the reservoir in addition to a number of radiators of varying sizes. These components have to be kept at a safe distance from the motherboard and given adequate room to breathe.

Even if you are able to store all of your components inside the case, the case itself must be able to ensure that all of the components are kept at temperatures that are optimal for them or as cool as possible. This may be difficult to accomplish with cases that are small in size, but it becomes easier as the size of the case increases.

Due to this, full tower cases are a substantially superior option for water cooling. You can also get away with water cooling in a mid-tower chassis, whereas mini ITX models are not recommended for this application. The space will also be essential since it will enable you to set up your cooling loops as well as any accessories that are necessary to cool specific components.


When considering which PC case to purchase, compatibility should be at the top of your list of priorities because it is the single most crucial aspect of buying a water cooling PC case. Even though the vast majority of computer cases offer at least some level of support for water cooling, you still need to make sure that they are compatible with your selected components.

Particularly, be sure to check that your selected case can support your motherboard and offers a sufficient amount of clearance for the various components of your computer, such as the power supply and the graphics cards. The case should have sufficient size to house all of your water cooling parts, provide the space to organize all of the cables, and be generally efficient in its airflow configuration.

Moreover, in-built water reservoirs and reservoir mounts are also wonderful complements to any PC case, but they are not necessary. Your primary focus should be on compatibility with the radiator sizes that you plan to use, as well as the fans and reservoirs that go along with them.

Cross-checking the compatibility of your components with your case will save you a ton of hassle down the line.


A decent PC case can be identified as one that has adequate airflow relative to the size and number of the components it will house. Along with that, it is a good idea to have a case that is large enough so that you will have room for upgrades in the future without having to modify anything else about the system. There are several reasons why merely installing additional fans cannot always be the solution.

As a result, your first option should be to select a case that has been constructed in such a manner that it not only provides sufficient room for optimum airflow but also is intended to improve upon that.

You have a wide variety of options available to you due to the abundance of PC cases now on the market, which range from some executions that are too enthusiastic to others that are straightforward but extremely effective. By keeping system temperatures and dust accumulation to a minimum, which further ensures the lifespan of concerned components, adequate airflow may be achieved.

Be sure to look for mesh panels and dust filtration when selecting your desired case. Even if you plan on water cooling, airflow is crucial since it is required to cool down your radiators as well as the graphics card and other components. Maintaining the ideal airflow conditions in your case is easy to do with the aid of our comprehensive guide that explains how to optimize your airflow.

Design and Aesthetics

The design and overall look of the case itself lead us to our final point. If you are a PC owner and you want to show off your rig in all its glory, then the aesthetics matter a lot. From the perspective of functionality, it is not at all significant; however, there is a certain confidence and sense of pride that comes with a well-designed PC.

This particular realm also comes with a lot of diverse viewpoints, so even if there is a case that you really appreciate, there is still a good probability that there is someone else there who does not actually appreciate it. It all comes down to personal opinion, so it doesn’t matter if you prefer stealthy black cases to those that stand out with their RGB lighting in a white chassis.

The layout of the PC case has an effect not only on its dimensions but also on the number of cables and components that may be housed within it. Therefore, it can still be functional in some specific scenarios. Nevertheless, it is important to consider the design and aesthetics of your PC case before you finalize your purchase decision.

Best Water Cooling Cases - FAQs

What is the difference between a full tower and a mid-tower case?

The difference between a full tower and a mid-tower case is that a full tower is much larger in size and heavier in weight than a mid-tower case. Generally, full towers measure roughly 550 – 750mm tall and 220 – 320mm wide. However, it can vary depending on the manufacturer.

Is water cooling better than air cooling?

Water cooling can be considered better than air cooling in terms of pure thermal performance. AiO water coolers also have the benefit in the department of aesthetics, but they are more expensive than comparable air coolers. Air cooling offers better value for money and also does not have the risk of leakage.

Does custom liquid cooling require maintenance?

Custom liquid cooling does require a bit of maintenance. Nowadays, there are many products available on the market that decrease the likelihood of contamination in the loop. However, personal care and attention have no substitute and even a perfectly prepared liquid cooling loop would require a bit of maintenance from time to time.

Can I use any case for custom water cooling?

You can use any case for custom water cooling as long as it has enough space to physically hold all your components. You should also make sure that the case you select has mounting points for your radiator of choice. Moreover, it is wise to select a case that has good airflow for better performance.

Is custom water cooling worth it?

A custom liquid cooling loop is worth it if you want to improve the temperatures of your CPU drastically while also improving the overall aesthetic of your PC. However, if you are looking for the best price-to-performance ratio, then you might be better off with a standard AiO cooler.
