  • MASSIVE COOLING OPTIONS: Up to 18 fan mounts and room for up to four 480mm radiators simultaneously.

Corsair’s Obsidian 1000D is a beast. Technically, you can install two PCs in this case with two or more power supplies. If you wanted to create a truly unique standard tower, this is the case for you. This super tower case is huge in every sense of the word. It weighs 65 pounds and measures 27.4 H x 12.1 W x 27.3 D inches. Such a large case also provides enough space for many cooling options. It can simultaneously house up to 18 fan mounts and four 480mm radiators.

Your tower monster starts out with a wide range of cooldown abilities. The 1000D can accommodate four 480mm radiators and 18 fans at the same time, giving you both air and water cooling. Installation of fans and radiators is also a breeze, with modular and telescopic brackets in the cooling bay. Overall, the 1000D pretty much requires some sort of custom cooling setup, due to all the space and ease of installation. To help keep things neat and orderly, the 1000D uses a three-chamber design, with French-style doors that provide easy access to the rear compartment and four removable tempered glass windows on the side. Overall, the look is very clean and utilitarian and the camera design easily compartmentalizes even the most extreme dual-system builds.

The CORSAIR Obsidian can accommodate two radiators in the front. Radiator sizes can range from 120 to 480mm. The rear of the case, on the other hand, can hold a 240mm or 120mm radiator, while the top can accommodate a 140mm to 420mm water cooling system. This box also comes with a built-in control for the fan and light. Installation of fans and radiators is also easy with the case’s telescopic radiator trays. Expanding your build shouldn’t be a problem with this super tower case, as it can support up to five 3.5-inch hard drives and up to six SSDs.

Hardcore gamers will certainly appreciate the ability to stream and play from the same tower thanks to the 1000D’s simultaneous dual system support of an E-ATX motherboard and a Mini-ITX motherboard. Another great feature of the 1000D is the huge storage media. Eleven separate bays house up to five 3.5-inch hard drives and six 2.5-inch SDDs. The staggering storage capacity is very much in line with the brand of this tower that tries to offer more of everything. Of course, no modern build would be complete without RGB support and the 1000D is no different. Corsair’s iCUE software governs the fan and light settings through an integrated Commander PRO controller. The controller gets the job done without complaint and is very easy to use.

Overall, the Corsair Obsidian 1000D is an excellent choice for a water-cooled PC version. Its three-chamber design allows ample space and provides connection points for any type of custom-cooled build, while the radiator capacity is best-in-class. You will need all the cooling capacity you plan to build the 1000D to its potential and load it with a dual system configuration and maximize its 11 storage units in total.

All in all, the Thermaltake Tower 900 Black Edition is a capable super tower that packs a lot of top-notch real estate.

NZXT H500i Compact ATX Mid-Tower PC Gaming Case

NZXT H500i - Compact ATX Mid-Tower PC Gaming Case...
  • Premium quality: All steel construction with the sleek h series design; available in four color...
  • Smart device: Built in RGB and digital fan controller powered by cam, delivers Hue+ and grid+...
  • Adaptive noise reduction: Optimizes cooling and noise balance for the best gaming comfort

NZXT H500i is built with durability in mind and is among the Best Cases for Water Cooling. It is made entirely of steel with a tempered glass panel. The tempered glass panel is well made and easy to install and remove using a single screw to hold it in place. Regarding cooling, the configuration of the mini itx micro atx housing provides good airflow, even with two Air F120mm fans. With plenty of space for extra fans, you don’t have to worry about high temperatures.

Another pleasant surprise is the silence of the H500i. NZXT’s decision not to cut corners on the quality of the materials, thanks to impressive sound insulation. As a bonus, the smart device provides a silent preset that minimizes fan noise. If you are looking for perfect PC cases, you will be very satisfied with it. The H500I NZXT comes with a signature cable handling bar that simply gives the routing hole a .K for a smooth appearance. Features like routing channels and cable tie strips let you manage without just thinking too much about it. The biggest drawback is the CAM software that powers the integrated smart device. Many users have solved problems such as software not loading properly, lost functionality, LED control not working, etc. Since most of the problems have occurred with older versions of the software, make sure that your latest version ( at the time of writing) should deal with it.

The enclosure has seven more wide slots, multiple drive episodes, and a port for an audio/microphone jack, as well as two USB 3.1 GEN1 type ports. Now, this case is a great choice when it comes to cooling power. It provides great air circulation despite having only two AirF120mm pre-installed. You have enough space to add more fans and no need to worry about the extra heat. It may have a 280 mm wide radiator at the front, another 120 mm at the rear. The matter is also fairly silent, which proves that the company was not behind in its conception or in picking up the materials. This PC case is great for water cooling and quiet operation, so we hope you will be very happy with this choice.

Great cable management is the signature of NZXT cases. It comes in the form of a bar that simply covers its routing hole and gives your PC a clean look without allowing the cables to ruin your construction. Naturally, this allows you to use routing channels, tapes, and more to keep the wires tidy in the best possible way and keep extra space for the things that matter. However, there is also a difficulty in referring to this model, and it is its CAM software, which powers the integrated smart device. The software is often reported as flawed and may not load properly, miss some functionality, or even cut off your LED commands. Since reports started arriving, the software has received an update that fixes most of its issues, so always make sure you have the latest version installed.

Rosewill TYRFING ATX Mid Tower is a good choice for beginners and those who don’t like complex reader installations. It comes with pre-installed fans that provide a solid foundation for your first build. For some tips on how to get started, check out our ultimate guide on how to build a gaming PC.

One thing that is not satisfied in this case is the spacer design: they are difficult to insert into the spacer holes by hand, so you will probably need to use tools and lots of power. This is a very neat professional enclosure with I / O panels mounted on top and a translucent panel with a side window. Additionally, this model also has quite an advanced cooling system, but we will get back to it soon.

This is a mid-tower case that is large enough to hold something that you can store in a complete tower case. It is one of the widest mid-tower models on the market, not only with great functionality, but it is also offered at extremely low prices. It is very user-friendly and suitable for beginners of PC building or for those who do not want to complicate matters. As a cool, it offers two pre-installed fans, although it can support three additional fans. Also, it can support a processor cooler up to 160mm, as well as 360mm long water cooling radiators on the front and top panels. For the mid-tiered case, it is worth a shot.

If I could use any word to describe the cursor Obsidian 750D, it would be standard. While the price may discourage some people, it has been done so well that it justifies the exceptional construction cost. The housing is made of steel and brushed aluminum with smooth edges and glass panel hinges that fit perfectly. The OBCDian 750D provides plenty of space and has slots up to four SSDs. Cable operation with a removable channel to hide the cable is smooth and easy. One drawback is that Corsair has decided to move the screwed top panel to this model, and unscrewing it every time does not seem to be an optimal solution. This case is quite heavy, as in most cases made from solid materials. This is not necessarily a problem, but if you like the light case, remember something.

Phanteks Eclipse Steel ATX Mid Tower is a very good budget case. This is a very economical package considering that it can accommodate any motherboard, including e-ATX. The front panel provides a variety of ports, such as a microphone and audio port, two USB 3.0 ports, as well as an RGB switch. The enclosure comes with enough space to include two 3.5-inch drive bays, a 2.5-inch drive bay, and your further 2.5-inch drive bay. There are a total of 7 PCI slots, and it even comes with a 120mm exhaust fan on the back.

This housing has two very easy to access filters – top, bottom, and front. But the most notable part of the case is its great cable handling, it includes velcro straps and can help you root your cables easily. This case combines both performance and aesthetics, and it looks both elegant and professional in addition to being highly functional. This is a great option for those on a tight budget, so think about it.

Thermaltake V200 Tempered Glass RGB Edition
If you are looking for the best budget, Thermaltech V200 is the winner. This RGB version comes with seven different fan colors and many customization options, such as controlling RGB fans using the front button or motherboard. One thing you will like about this case is how wide it is. There is plenty of room for larger components and extra fans or multiple hard drives, which gives you more freedom when designing the layout. There is no optical drive in this case, so if you want to use CD, DVD, or Blu-ray, you need to fix an external optical drive. Do not trust the manual to help you. Instructions like Game of Thrones’ Azor Ahai’s predictions are vague, without explaining how specific components can be installed.

Cases For Watercooling

Preinstalled vs. ready for water cooler

It depends on your experience of making custom PCs. Newcomers find it easier to choose a case with a cooling system, so they don’t have to worry about airflow and cooling functionality.

More experienced users usually choose a housing ready for the water cooler and choose their components.

Material support: Compatible with your components

The most important thing about any enclosure is that it can support all the components you want to install. Before making a choice, enclosure details such as IO configuration (number of ports, number of port types), fan configuration (number of mount locations, number of fan types), RGB lighting, compatibility of motherboards (ATX, Micro-ATX, Mini-ITX), etc.


Consider its effectiveness when looking for a case. What does the airflow look like, and how many fans are there with it? What kind of water cooler can it support? Check the overall capacity and quality of the cooling system with information like fan speed, size, model, etc.


You can choose between mini, medium, full and super towers. It is up to you to choose the size that you are most comfortable with, but be aware that two cases of the same size often have different amounts of free space depending on the case management.
Ideally, you should first install a PC case that you are planning to buy and then choose a liquid cooler. This way, you can avoid unwanted compatibility issues and need to replace/order a new cooler.


The amount of noise your circle will make is proportional to the number of your fans. Be careful when choosing the type of fan, as well as determining the speed, size, and model noise level. The materials used for the case will affect the sound level – some provide better soundproofing than others.


The choice of design depends entirely on your personal preference. Ask yourself if you want a residence with minimal, monochromatic design or LED fans. Most cases come with a glass panel that allows you to present the interior layout and various features that help to hide the less presented elements such as wires.

Frequently Asked Questions

Do I need water cooling?

You don’t necessarily need it, but water-cooled is better than air cooling because it removes excess heat quickly and doesn’t heat the inside of the case. The best high-end gaming platforms are much safer with liquid cooling installed.

Which liquid is used in liquid cooling?

It depends. Usually, it is water, deionized water, glycol/water solution, and liquids such as fluorocarbons and PA.

Do you need to replace the liquid cooling?

It depends on how cool you are. Closed-loop cooling does not require fluid replacement. The open-loop system requires fluid replacement periodically.

What tank do I need to cool the water?

It depends on how many ingredients you have. If you have the required number of components for cooling, it is advisable to keep a tank.
However, most mid-range and low-budget gaming platforms will not require a tank.

Improves liquid cooling performance?

It depends. If your processor heats up slowly, liquid cooling will help it run at normal speeds. The best way to improve performance through liquid cooling is to overclock your processor, allowing it to run faster than usual.
