The most popular cases when it comes down to cube style PCs tend to be compact. That isn’t the case for Thermaltake’s Level 20 XT, a monstrous E-ATX and ATX cube case designed for high end rigs with custom water cooling systems.

The chassis is big, but worth considering if you’re into multiple overclocked CPU builds and other extravagant components. It comes with four chambers to accommodate up to 11 radiators.

The Level 20 XT has a unique horizontal motherboard tray to showcase your components through its copious 4mm tempered glass panels.

The flat tray separates the case’s two chambers and also makes for an efficient separation between the power supply and graphics card compartments.

This content is good but still needs improvement. For example, the information about “radiators” could be explained so that the reader will understand what it is rather than just looking at a picture of what seems like a window air conditioning unit.

Explain to readers why your PSU and drives are located inside of their own space instead of in some other area before telling them that radiators can also be installed here. Then give a few ways for the reader to determine if this is such a viable place for installing specific components.

For example, this comment may have been posted: “The two vertically mounted radiators were completely inaudible under full load. But I would advise using smaller fans and using push-pull configuration.”

Like Thermaltake’s open-air PC cases, the Level 20 XT is built to withstand years of upgrades, tear-downs and rebuilds. With removable panels, racks and customized setups that leave little wiggle room for anything other than absolute modularity, the XT version of the Level 20 takes a page from our own book – The Engine.

Level up your gaming with the “Dismantlable Modular Design” philosophy that allows you to tear down A Level 20 PC case for ease of installation and upgrading!

The Thermaltake Level 20 XT isn’t cheap, but it’s hard to deny that it’s one of the most striking gaming cube chassis money can buy right now. Combine that with cutting-edge features, and you have an advanced system tailor-made for professional grade PC builds

Corsair’s Crystal Series 280X RGB is a new and modern build from Corsair, featuring crisp tempered glass walls – with support for two 140mm radiators – and the option to add in a pair of fans. It also comes with a sleek-looking design language that many gamers should be quite familiar with.

Corsair boasts of several technical aspects regarding the case such as its “Direct Airflow™ Path Cooling.” Rather than passively cooling via a mesh-meshed side panel, airflow paths are configured so that fresh intake is brought in from the massive 250mm fan in the front.

Hot air is exhausted through 4 exhaust fans and leftover heat is vented out of the top or bottom of the enclosure (where HDDs can be mounted).

And with advancements like these, it’s no wonder why the Corsair 780T is so popular that they had to make a custom plastic cover to cover up all their logos!

The use of separate chambers alleviates the issue of heating hard drives thus effectively improves cooling. This is because when there are no drive cages, air can run directly to the heat-generating components, like a computer’s CPU and GPU, therefore maximizing relief to those components during stress tests.

Corsair pays special attention to their louvers and ports by including dust filters with premade holes for fans and power supplies to prevent dust build-up in the case over time.

This is a thoughtful move on Corsair’s part as you don’t have to worry about replacing or making your own filters, saving you valuable time.

The Corsair Crystal Series 280X RGB with Lighting Node PRO RGB controller, integrates three tempered glass panels which all help achieve a gorgeously elegant, tessellated aesthetic that is sure to leave any onlooker in awe.

With the addition of its two LL120 RGB fans, the Crystal Series 280X RGB microATX tower case, not only features Airflow Control Technology for impressive cooling capabilities and two pre-installed anodized custom LED lighting zones in the front and one in the back to offer an astonishing illumination experience, but also allows you to seamlessly incorporate your own LED lighting upgrades!

When it comes to gaming brand awareness in the United States, Corsair happens to be one of the leading manufacturers of PC memory, PSUs and cases. (1)(2)(3) As such.

Corsair has its hands in developing a number of accessories for graphics cards including the 280X series. The line features three different products: the 280X RGB, 280X Whiteout and 280X Blackout.

While we might not be as familiar with Anidees compared to other companies like Corsair, their innovative AI Crystal Cube AR V3 is a quality contender in the RGB PC case arena.

Announced at Computex 2018 , the company’s latest addition to their growing catalogue of PC cases comes equipped with tempered glass panels that feature customizable RGB lighting.

And while it may seem flimsy at first glance thanks to its glass construction, this case thankfully doesn’t suffer from the same fragility issues found in some competitors until you reach their high price points.

The Crystalfontz Cube comes standard with five AI Aureola RGB fans, two LED strips (one for the front and one for the back panel), and an AI Aureola V2 fan hub.

The layout of the Anidees AI Crystal Cube AR v3 case is pretty special. Instead of using a standard dual chamber internal structure to protect your components, the main compartment of this case is separated by a plastic wall and acts as an insulator to keep heat production lower in this section of your unit.

Not only that, but it also makes it very easy for you to set up your cable management system, making sure everything looks nice and clean inside your build.

With both a USB 3.0 port on the outside and four on the interior, there’s more than enough room to accommodate any peripheral you might have lying around.

The Anidees AI Crystal Cube AR V3 is an all-in-one liquid CPU cooler that also comes with fans, capable of running in two different fan setups.

In the first option, a combination of 140 mm and 80 mm fans blow into dedicated chambers to keep your CPU cool. A powerful array of 4 140 mm fans can be added to the second option by using the included fan bracket.

If you like the look of Corsair’s Crystal Series 280X RGB but wish you had something bigger to show it off in, Anidees has an option for you.

The AI Crystal Cube AR V3 is designed similar to the Crystal Series 280X RGB case but instead of being a cube, it’s rectangular in shape so you can place it on its side rather than upright.

If you’re familiar with Fractal Design’s cases, then you already know what to expect from the Node 804.

It’s a sleek, minimalist case that contains all the charms of previous models like expertly executed minimalistic design elements and excellently built structures which are designed for micro ATX and mini ITX rigs.

The 804’s attractive design and efficient cooling ensures heat takes its leave in two separate compartments. This creates a positive pressure effect which filters hot air from the PSU, ensuring a stable operating temperature at all times.

In other words, you get one of the best-looking cases we’ve seen as well as an optimal configuration to protect your valuable equipment from overheating.

The Node 804 supports more radiators than any other mATX case currently on the market, enabling enthusiast users with liquid cooling to build systems that not only handle maximum performance but do so in a way that is visually appealing.

With four full-sized radiators supported simultaneously, two in each of its chambers, the Node 804 allows you to embrace your inner water cooling nerd while making it look super stylish as well.

The main drawbacks of the Fractal Design Node 804 stem from it being on the older side. One example of this is the glass in its left side window panel.

It’s not as stylish as a full glass panel, which is more common on newer cases. And at first glance, the interior seems dull because there isn’t much else beyond the few available ports and buttons.

However, this is really just a question of aesthetics – those who prefer an overall minimalist approach may be drawn to the 804’s minimalism.

The original Node 202 chassis was designed with customization in mind, and its larger brother is of no exception.

The Node 804 offers an elegant solution for anyone who prefers a smaller but just as clean PC build without compromising on valuable cooling options or manufacturer quality.

At its price point, the Thermaltake Core V21 is a top choice for users looking to build an affordable high-performance cube gaming PC. It’s got enough features to stand out from typical budget cases while keeping costs down and it looks good while doing all of this.

Dual chamber layouts have become the standard in products released at the tail end of 2021 and Core V21 is no different.

The Core V21 offers an innovative new design unlike anything ever seen before, giving you the option to vertically mount your motherboard via a 90 degree installation.

This fully maximizes space within a medium sized cube case. Previously only possible in larger chassis’ like its bigger brother the Level 20 XT, this new feature makes the CORE V21 one of our most unique cases ever!

The Core V21 can stack two units on top of each other and offer users an extra storage space for anything from something as simple as extra drives to a dedicated water cooling chamber.

This is a great idea for someone who might just be getting into PC building with limited funds available because it means how you then take that small setup and gradually upgrade to bigger and better things.

A reputation lay in the hands of writers, so when it’s noticed that mistakes are present, the readers may not trust the content the writer produces in the future.

The thing about Fractal Design is that the company looks at everything from a unique perspective, even simple things like case design.

Take for example the Modern ATX Cube – a mini-ITX tower that packs all of the same features as its larger counterparts into a space just half the size.

Most would consider this kind of feature to be overkill, but it’s actually quite practical when you think about it:

Thermaltake Core V21 has a very good price for what it offers. The cable management system is well thought out, and you have many options as to how you can place your components in this case.

There are also a lot of cooling options that are easily accessed and can be improved upon by the user at any time without having to buy additional hardware if they so choose.

The design leaves something to be desired but it doesn’t matter because function over form wins out every time, especially in an entry-level product like the Core V21!!!

One of the main things that make SilverStone’s SG13 case stand out among the other cases in its price range is the fact that it can hold a micro-ATX motherboard, despite being a cube PC case.

While this may not be important to some people, it’s certainly something extra to consider if you plan on creating a powerful yet small form factor system.

Most people also appreciate how densely packed optical drives and hard disk drives fit within this chassis (because they’re often limited as far as space goes), as well as how easily they are removed / installed due to their conveniently placed PCI access holes.

They also like the fact that it can be used as an efficient home theatre PC, because it comes with vents for carrying sound from the front audio ports to both sides of your room.

The SG13’s small size makes it the perfect candidate for a gaming rig. As it only accepts standard-sized GPUs, you’ll have to compromise on CPU power.

This shouldn’t be too much of an issue as most graphics cards are faster than modern quad-core processors anyway.

However, users will still have to deal with cooling limitations, but this should be easy enough to do as mini ITX cases have plenty of options when it comes to cooling solutions appropriate for such computers.

The SG13 is available with white and black color schemes, as well as all-pink. In addition to this model that features two USB 3.0 ports on the front, there is also a version with a USB-C connector.

The SilverStone SG13 is a simple to-the-point SFF case. It’s a cube with an HTPC aesthetic, but it has quad-seasoned support for video cards, microATX motherboards, and Micro ATX power supplies in addition to requiring at least an SFX power supply that is rated for at least 180W (which means you’ll be getting 80 PLUS certified efficiency at 115V since the usual lowest wattage rating on any PSU is 300W).

Part of our redesign was also to simplify the language; this one got rid of the “”test”” thing because we’re trying to explain how they can be used by people who don’t want much fuss or attention when using it.
