Water cooler PC cases work the same as the air cooler does. The purpose of these cases is only to cool the system and prevent overheating the components. The base plates absorb the CPU’s heat and transport the heat by circulating water to the radiator and throughout the heat from the system.

In this buying guide, we try our best to evaluate the importance of the best cases for water cooling for your system’s components and tell you which one is best.

Case Size:

The case size depends on the size of the motherboard; it is only up to you which one is according to your needs. While making a purchase, make sure to be aware of the headroom as it depends on the design or layout of the cases. Some of the following sizes of liquid cooler PC cases are available in the market.

  1. Mini Tower: These are smaller in size and are suitable for the small set-up. These cases are mostly 35 to 40 cm high and have small space for the components. As we know that these are small in size, that’s why only designed for those people who want a small set-up. In the best small water cooling case, there is a setback: they cannot disperse the heat properly and are not suitable for the large set-up.
  2. Mid Tower: These medium-sized PC cases are 40 to 50 cm high and are the standard size of PC cases for daily use and are also mountable. They the most popular size among people as it is taller than the other sizes. However, for some users, the width and the depth will not vary as much as they can hold all significant components. These cases suit best for the home or even for desktop computers.
  3. Full Tower: These are the largest and can accommodate all large components and are suitable for all systems. These are large boxes with spacious interiors and lots of slots on the front and rear. Full tower cases are larger and may handle heavier desktops, like servers and file-sharing computers.

Radiator Compatibility:

A radiator is a PC component responsible for exchanging heat from a liquid source to the atmosphere. This process makes sure that the components of your system remain safe from overheating.

When you want to buy a CPU case, choose the one with enough space for radiators. If you want your system to remain cool and to flow out the heat properly, then look for the radiator support given in your case. The enormousness of the case matters a lot for the positioning of the radiator, and height or width may affect the cooling process. 

Mini ITX is not a good choice for you because they do not support properly cooling the system and using limited components. Larger cases offer large space, more locations, and also have more mounting possibilities. Our recommended top PC cases for water cooling are best due to their assembly of a custom-made water-cooling with several radiators.

Drain & Fill Ports:

Drains and fill ports are used to emptying and effortlessly filling your loops. Place these valves in position and have easy access for the greatest experience. They are responsible for the fluent working of the water cooling system.

Some cases have a feature to drain and fill the ports. From this feature, you may have easy access to the specific areas so that you can fill up your system and drain it. Sometimes it may look pointless, but the ports are suitably placed and make the process easy and convenient.

Motherboard Size:

The motherboard is the main component of any computing system. It is the main printed circuit board in the computer responsible for all the functions. It is the central communication backbone and connectivity point of the computer from which all external and internal peripherals are connected.

Best cases for water cooling come in different sizes and form factors, but it depends on the size of the motherboard. That’s why before purchasing the PC case, first decide your motherboard size and the other requirements.

To effectively cool down the GPU, the best gaming cases for water cooling have reasonable GPU clearance. The space around the GPU helps to eliminate the heat away. That’s why it is important to have enough GPU length space to accommodate easily.

Connectivity with Other Devices:

Connectivity is the ability to link systems or application programs. Mostly these connections are established already and don’t need any changes to the applications or the system.

In most cases, the front panel has connectivity for audio input and outpout with USB ports. At the same time, the rear points mostly have cable connections. Best white cases for water cooling have a USB 3.1 Type-A or Type-C connection, which is a plus point. Make sure that your frame is compatible with the peripherals you want to connect.
