The 10 Best Water-Cooled PC Cases in 2021

Best water cooled pc cases

What makes the best water-cooled PC case? It all comes down to chassis size, radiator support, and the ease with which custom water-cooling loops can be installed. Since water has a higher thermal conductivity than air, water-cooling cases have a higher density, heat power, and thermal conductivity, allowing the computer device to transport heat over longer distances. However, if water leaks on the hardware, the water-cooling system can be harmful, which is why it is important to use the best and most effective water-cooling cases that offer the best protection for liquid cooling technology. If you’ve decided on a water-cooled pc case, the first step in putting your strategy into action is to choose a case that will suit your liquid cooling system and show it properly.

Today, we’ll look at the 10 best water cooling pc cases possible in 2021. If you’ve decided on a water-cooling system for your PC, the first step in putting your plan into practice would be to have a case that will suit your liquid cooling system and show it properly.

Thermaltake 900

  • Dimensions: 19 x 16.7 x 29.6 inches
  • Motherboard Support: Extended ATX
  • Additional Features: Full tower, 4 USB, 54 pounds
  • Cooling Method: Water

Thermaltake Tower 900 REVIEW:

The Thermaltake Tower 900 is unquestionably not for you if you’re looking for a low-cost water-cooling-friendly case or something with enough space for a big air cooler. In reality, even if you’re looking for a high-end case to use with water-cooling components, this is the case for you. Many recommended it as the best full tower water cooling case. So if you want your water cooled computer cases, choose this! As it is among the best cooling water cases.

When Thermaltake first introduced its double-width Tower 900 at Full Tower height, it may have been asking the same question. Average buyers may be concerned about the case’s weight, but we doubt there will be many lined up for a case nearly 30″ tall and over 17″ wide. My biggest challenge was aligning the lighting and non-reflective surfaces to display Tower 900’s features without glare from its massive tinted glass.

USB ports, two headset jacks, power and reset keys, and power and HDD operation LEDs are all available. Thermaltake seems to recognize that seasoned builders favor motherboard-based automatic fan power. With left and right panel vents covering four dual-pattern (140mm and 120mm) fan mounts and a rear panel mount for two more 140mm or 120mm fans, the Tower 900 is all business in the back. A reflection on the camera lens produced streaks in the image.

All fan mounts, including the internal fan mount atop the front hard drive cage, were shown in detail by Thermaltake. Two 3.5” trays with 2.5” drive mounting holes, two 2.5” trays, and an additional 5.25” bay make up the front portion. By placing a digital controller in that position, Thermaltake creates a more compelling counterpoint in its marketing pictures.


  • Large enough to accommodate almost any liquid-cooling setup
  • Stock fans provide excellent cooling


  • Some people won’t be able to lift it because it’s too heavy
  • Some people find it difficult to move due to the weight

Thermaltake Core P90

  • Dimensions: 18.5 x 18.5 x 24.2 inches
  • Motherboard Support: ATX
  • Maximum graphics card length: 320mm
  • Additional Features: Mid tower, 37.9 Pounds,
  • Cooling Method: Water

Thermaltake Core P90 REVIEW:

Thermaltake has undoubtedly gone further than anyone in terms of pushing the boundaries of chassis style. Considering the price, there aren’t many snazzy features included, with only a regular front panel with the normal ports and buttons – no RGB lighting, fan controllers, or USB 3.1 Type-C here. The main attraction, at least for those who like a bit of DIY, is that the case comes with a large number of components that must be assembled, including a PCIe riser cable.

The Thermaltake Core P90 Tempered Glass is fully open, allowing air to flow freely into your cooling hardware. The effect is very low CPU and GPU temperatures, but it’s worth remembering that there won’t be much airflow over components like the VRMs or your liquid-cooled graphics card.

The build quality is typical Thermaltake, with panels that are very flexible and screws that don’t feel particularly good, but the whole thing goes together well enough and does a decent job. Each side is presented and protected by 5mm thick tempered glass panels, with extended glass mounts for easy cleaning.

Supporting three different positioning formats (Wall-mount, Vertical, and Horizontal), the PC can be angled in a number of ways to fit users in a variety of configurations. The Core P90 suits your PC like never before, thanks to its angled frame design.


  • Build Quality
  • Good Design
  • Wall Mount
  • Vertical & Horizontal Placement


  • Open Air Chassis (Dust Magnet)
  • No Wall Mount Brackets Included

Lian Li O11D-XL

  • Dimensions: 23.75 x 15 x 23.3 inches
  • Motherboard Support: ATX
  • Additional Features: 13.75 Kilograms, tempered glass material, full tower
  • Cooling Method: Water


The O11 Dynamic XL is packaged in a brown cardboard box with an inverted image of the chassis exterior and interior on the box’s larger sides. There isn’t much detail on the smaller panels other than checkboxes that indicate which version is inside. You get all the standard parts, such as screws, but Lian Li also throws in some extras like HDD plates that can be moved to the chassis’s base and help with liquid-cooling setups.

The Lian Li O11 Dynamic XL looks similar to its smaller sibling, the Lian Li O11 Dynamic, right out of the box. The XL, as the name suggests, is bigger, allowing for more cooling and storage, but there is also a slew of other improvements, as we’ll see later. The O11 Dynamic XL’s main side is entirely made of glass, while the opposite side is solid and features two massive air vents on the inside, both of which are protected by magnetic dust filters.

The RGB strip in the front, between the aluminum and glass panels, looks incredibly spiffy when it is turned on. The interior of the Lian Li O11 Dynamic XL looks fantastic until it is put together and the cables are routed thanks to the well-placed, angled, rubber-grommet-covered openings. As you can see, the whole cable mess, including the wiring from the Thermaltake Floe 360 RGB, is concealed in the trench next to the HDD cages.


  • Aluminum frame and glass panels on a metal frame a perfect mix
  • Excellent set of modern I/O
  • Stylish RGB element with capable controller included
  • Can hold up to three 360 mm radiators


  • It would have been better if there were more Velcro strips.


  • Dimensions: 10 x 27 x 23 inches
  • Motherboard Support: ATX
  • Max Graphic Card Length: 350 mm/ 13.77 inch
  • Additional Features: Aluminum material, Mid Tower case type
  • Cooling Method: Water & Air


Since it comes unassembled, Cougar’s unique packaging is worth a look. It’s up and the builders peel back the layers to uncover more bits. Three fans with grills, several adhesive cable ties and tabs, many screw sets, two feet, and electrical power bracket, and tray, a drive tray that serves two 2.5” or one 3.5” drive, and five cross braces are among the items included. Two more 2.5” or 3.5” diameter drill bits. Prior to motherboard installation, two more 2.5″ or 3.5″ drives can be added to the back of the motherboard tray. The top panel of the Conquer supports two 120mm radiators in the front and three 120mm radiators on top, and the upper structural panel opening is wide enough to feed hose fittings from above if needed. We put these there because the chassis has three fans.

Superior Expansion- You can also show off your high-end and versatile gaming setup, which includes full-size graphics cards up to 350mm, with incredible vision. COUGAR Conquer is a one-of-a-kind masterpiece in the realm of your dreams. Extremely Cooling Performance- For gamers, overclockers, and PC enthusiasts in general, cooling is crucial, and Conquer delivers.

Conquer’s innovative aluminum framing style deviates from conventional cases, making it ideal for modders. It makes it simple to build and change the scenario. Modders would have unparalleled amounts of flexibility to build a dream case beyond imagination thanks to its superior expandability. Water cooled CPU cases are indeed worth the money.

Corsair Obsidian Series 1000D REVIEW:

You’d think this product is just for the seasoned builder, but where else can you gain experience? Surprisingly, this case is designed for those that need extra space and need to store two computers in one case. Also, it is the best full tower case for water cooling. Do you want to stream while gaming, for instance? After all, it is true that saying something is better than doing something.

The GUNGNIR 100 is a mid-tower case, so it’s not particularly large despite its impressive features and hardware support. It measures 510(D) x 227(W) x 525(H) mm, making it ideal for large radiators.

Rosewill ATX Mid Tower

  • Dimensions: 22 x 20.5 x 12.4 inches
  • Motherboard Support: ATX
  • Additional Features: 23 pounds weight, Mid-tower case
  • Cooling Method: Water

Rosewill ATX Mid Tower REVIEW:

The Cullinan uses tinted glass panels on three sides to make a bold point about Rosewill’s luxury product strategy. The front panel’s moderate weight means a thinner glass insert, while the thick 0.20″ (5.2mm) tempered side panels add rigidity without the need for frames.

With two USB 3.0 and two USB 2.0 ports, headphone and microphone jacks, and a two-speed fan controller, the front panel ports are more common in high-end situations. Both the power and reset buttons have black-anodized aluminum caps, with blue (power) and red (reset) rings circling them (HDD activity).

The 2.2″ of above-motherboard radiator capacity, as well as two knock-outs for external radiators, are visible on the back of the case. The included 120mm rear fan can be upgraded to 140mm, and slotted fan mounts allow for vertical adjustment of various rear-mounted radiators.

Any 1.5″-thick radiator mounted there will touch the power supply shroud, which covers cables and stops precisely 1.5″ short of included fans. The shroud is also riveted in place, preventing access to the cable connections on a modular power supply. Rosewill is the mid tower case, also the best case for water cooling.


  • Great appearance with tempered glass
  • Great noise deflection
  • 2 large radiators support
  • Top-panel dust filter
  • Good selection for USB ports


  • Mediocre cooling performance

Best Premium Build

NZXT H510 Elite

  • Dimensions: 16.85 x 8.27 x 18.11 inches
  • Motherboard Support: Mini ITX
  • Max Graphic Card Length: 15 inches (381mm)
  • Additional Features: 9050 Grams weight, Mid tower case
  • Cooling Method: Water


If you are looking for the best cases for water cooling and can serve good money then NZXT H510 Elite is the best choice. The case’s design and construction are excellent in this water cooling case. NZXT used a combination of plastic snaps and captive thumbscrews to make the case easy to open and disassemble while remaining sturdy enough to travel around; the front panel, however, is held in place by two tiny Philips head screws.

Pushpins in the upper corners secure the tempered-glass side and front panels to the frame. A single thumbscrew secures the side panel, and two small Philips-head screws secure the front panel. Behind it, two of the case’s RGB fans are installed.

An opening for a bottom-mounted PSU, seven regular expansion-card slots (plus two vertical for showcasing your graphics card), and an exhaust-fan mounting position with a 120mm fan can all be found in the back of the chassis. The impressive build is highlighted by the clean, minimalist style, classic cable management counter, and uninterrupted tempered-glass side panel.

The PSU intake opening in the case’s bottom is covered by a removable plastic mesh filter. The case is held approximately one inch above the ground by the wide, rectangular rubber-coated feet, which allow for easier air intake to the power supply. Thus get your water cooled pc cases ready.


  • Good thermal performance
  • Very stylish design
  • RGB lightning strip mounted


  • A little pricey

Thermaltake Level 20

  • Dimensions: 27.1 x 28.8 x 11 inches
  • Mother Board Support: Extended ATX
  • Max Graphic Card Length: 260 mm
  • Additional Features: Full tower case, Square shape, Metal body
  • Cooling Method: Water

Thermaltake Level 20 REVIEW:

Thermaltake outfitted this ATX mid-tower chassis with two 4mm thick tempered glass windows that take up the vast majority of the left and right side doors, respectively. Although the front and top panels are covered in mesh rather than glass, you can still see the massive ARGB-lit fans mounted on the front of the case through the mesh. The same can be said for anything.

The power button, hard drive LED, microphone and headphone jacks, and a button that can change the LED lights are all located on the left side of the case. The right-hand half of the front I/O panel has four USB Type-A ports, two of which are USB 3.0 and two of which are USB 2.0.

Building a device within the Thermaltake Level 20 RS ARGB has its advantages and disadvantages, but depending on the hardware you choose, it can be a relatively painless process. The motherboard is simple to install, and the case is large enough to aid cable management; essential cables, such as the CPU power cable, are not difficult to link.

Adding storage devices to this case is also easy. Three 2.5-inch drives and two 3.5-inch drives can be installed in the chassis, with one additional mounting position for two more 2.5-inch drives or a single 3.5-inch drive. Two of these drive mounts are visible and accessible from the left panel, while the others are concealed on the opposite side of the case.
