The Best Cube Computer Cases

Cube Computer CasesIn today’s guide, we take a look at a handful of the top cube-style computer cases. We’ve rated seven of the best cube PC cases and provided a rundown of what makes each of them a worthy option.

While not as popular as mini-ITX cases, or PSU shrouds, or tempered glass side panels, the cube-style computer case has carved out its own fan club among PC builders. Of course, a cube-shaped case can also be a mini-ITX case, or can have a PSU shroud, or can come with tempered glass panels.

Really, of the cube cases that are out there, there is a pretty wide range of the types of features they can offer. There are cube cases that can accommodate E-ATX motherboards, come in smaller form-factors, are perfect options for liquid cooling, and so on.

So, if you’re in the market for cube-style PC case, in this guide we’ll give you a list of some of the best options.

A Quick Look at the Best Cube Style Computer Cases

Below, we’ve picked four of the top cube cases currently on the market. We’ve selected our favorite all-around cube-style case (with price considered), an extreme option, the cube case with the most RGB lights (preinstalled), the best value option, and the best ultra-budget option. We’ve also included a few honorable mentions further down in this post as well.

1. Lian-Li O11D

The best overall cube-style case

  • Max Cooler Height: 170mm
  • ATX, Micro-ATX, Mini-ITX

The Lian-Li O11D is our choice for the best all-around cube computer case. I think you could make a case for the Thermaltake Level 20 VT here, but with the roomier interior and sleeker design, we gave the edge to the 011D.

In terms of specifications, the Lian-Li O11D can hold graphics cards that are up to 395mm long and CPU coolers up to 170mm tall. That will be more than enough room to house whatever kind of system you want.

The O11D also has support for up to 360mm AIOs/radiators on the top and bottom of the case, and up to a 280mm radiator on the side. So, there is a lot of potential to setup a custom liquid cooling configuraiton in the case—or to use a wide variety of AIO coolers.

Lian-Li’s cubed-style case also comes with plenty of cable management features, including a bunch of cutouts with rubber grommets. And, the case has a full tempered glass side and front panel, too, so you can show off your build.

Ultimately, for what the O11D brings to the table in comparison to the price it comes in at, you’d be hard pressed to find a better overall option among cube-style PC cases.

2. Corsair Crystal Series 680X

An extreme cube case option

If you’re working with a huge budget and you’re looking for a high-end cube-style PC case, then the Corsair Crystal Series 680X is worth checking out. This case does cost ~$250, though, so when we say huge budget, we mean it.

And, while the Cystal Series 680X doesn’t offer as much room as some of the cases on this list, it still has enough space to hold a high-end video card. And, it comes with some high-end features that you won’t find anywhere else.

For starters, its dual chamber design will make hiding your PSU and storage drives and doing cable management incredibly easy. The case also comes with three preinstalled RGB fans on the front of the case, (and a standard fan preinstalled at the rear of the case), a Corsair Lighting Node PRO (to help you coordinate all of your RGB lighting), and the ability to vertically mount your graphics card.

Ultimately, in terms of value, the Cystal Series 680X probably isn’t the best option. But, if you’re looking to go all out on your build and you want a flashy cube-style case that has some next-level features, then the 680X might be the case for you.

3. anidees AI Crystal

The cube case with the most RGB lights

While anidees is somewhat of an unknown among case manufacturers, it’s hard to look at their AI Crystal Cube cases and not fall in love. Not to mention, they come with a ton of RGB lighting.

The Crystal Cube is the second most expensive option on this list, coming in at ~$180. So, it might not be a viable option for everyone. However, it comes with three 5mm-thick tempered glass panels on the front and on both sides and it also comes with 5 RGB fans pre-installed. And, really, that’s likely where the premium for this case comes in, as the included fans from anidees cost close to $60 on their own.

For anyone that has the budget and wants a cube-style case that will stand out, in our opinion, the tempered glass and included RGB fans help make the AI Crystal one of the coolest looking cases around.

The Crystal Cube also has room to fit graphics cards up to 330mm in length and CPU coolers up to 168mm in height. It also has room to accommodate a 240mm AIO as well and can house larger extended ATX motherboards, too.

Ultimately, the price will probably be a tough sell for a lot of builders. However, if you don’t mind spending some money to get a really nice-looking cube case, then the anidees AI Crystal Cube might be an option you’ll want to consider.

4. Thermaltake Core V21

The best cube case under $100

  • Max GPU Length: 350mm
  • Max Cooler Height: 185mm
  • Micro-ATX, Mini-ITX

Our Rating: 8.4/10

The cool thing about cube-style cases is that there are quite a few budget-friendly options to choose from. The Thermaltake Core V21 (and the Core V1 listed below) are two such options.

The Core V21 comes in at just under $80. It is a compact micro-ATX case (it can hold a mini-ITX motherboard as well) that has plenty of room to house a high-end system. It can hold graphics cards up to 350mm long (which is nearly more clearance for a graphics card than any other option on this list) and CPU coolers up to 185mm tall.

It comes with one 200mm fan pre-installed on the front of the case, and every panel besides the acrylic see-through side panel has grills on it, which helps make it a great option for anyone who wants to maximize ventilation in their system

You can also mount your motherboard horizontally, or vertically in the Core V21, giving you some extra versatility in how you build your system.

Overall, the Thermaltake Core V21 obviously isn’t the greatest case ever built. But for those of you who are looking for a budget-friendly small form-factor cube-style computer case, the V21 is about as good of an option as it gets.

5. Thermaltake Core V1

The best budget cube case

Thermaltake Core V1
  • Max GPU Length: 260mm
  • Max Cooler Height: 140mm
  • Micro-ATX, Mini-ITX
  • Black & White

Thermaltake’s Core V1 is an even smaller version of the Core V21 listed above. It’s a mini-ITX case that looks very similar to the Core V21 and comes in at an even lower price (a little under $50.)

Like the Core V21, every panel but one on the V1 are all grilled to maximize ventilation. One of the panels has an acrylic window on it and the cool part about the Core V1’s panels are that they are all interchangeable. So, you can put the acrylic panel on either side of the case, or on the top as well.

The V1 can hold graphics cards up to 260mm long and CPU coolers up to 140mm tall. So, it is one of the more compact cases on this list and, as such, will be a bit more limited in what kind of hardware you can install in it. Still, there are mini graphics cards out there (the ASUS Phoenix RTX 3060 mini is only 177mm long), so you should still be able to build a powerful gaming computer inside of the V1.

The case also comes with a large 200mm fan pre-installed on the front and you can add two 80mm fans on the back. You can also swap out the 200mm fan on the front of the case for a 140mm or 120mm AIO cooler as well.

In the end, for under $50 you can land yourself a nice mini-ITX case that has plenty of space to house a high-end system and plenty of ventilation/cooling options to help keep your system running cool.

6. Thermaltake Level 20 VT

Honorable mention #1

Thermaltake Level 20 VT
  • Max GPU Length: 350mm
  • Max Cooler Height: 185mm
  • Micro-ATX, Mini-ITX
  • Black & White

Our Rating: 8.9/10

Check Price on Amazon

It’s tough to pick between the Thermaltake Level 20 VT and the Lian-Li O11D. Both are excellent cases with outstanding features (both offer nice aesthetics, multiple tempered glass panels, plenty of room, and excellent build quality).

Both cases can house high-end graphics cards and the Thermaltake Level 20 VT does come in at ~$30 cheaper.

However, the Lian Li 011D (in my opinion) has a more appealing design, can hold larger 360mm radiators, and is designed to keep the power supply hidden—which will make building an aesthetically pleasing system a bit easier.

But, these aren’t deal-breakers for the Thermaltake Level 20 VT, because there are builders out there who will prefer its design, will be fine with a smaller 280mm AIO cooler, and are skilled enough in cable management to make the PSU and its cables look good.

So, the bottom line is that, if you don’t mind the differences between the Level 20 VT and the 011D (or, if you prefer the Level 20 VT’s features), then this cube case from Thermaltake would be an excellent choice.

7. Fractal Design Node 804

Honorable mention #2

Fractal Design Node 804
  • Max GPU Length: 320mm
  • Max Cooler Height: 160mm
  • Micro-ATX, Mini-ITX
  • Black & White

Our Rating: 8.8/10

Check Price on Amazon

Fractal Design rarely disappoints with their cases and their Node 804 cube-style case is no different. With a unique dual chamber design, the Node 804 is perfect for maximizing cooling and ventilation.

Like all Fractal Design cases, the Node 804 sports a minimalistic design and comes with a brushed aluminum front panel.

For liquid cooling support, the Node 804 has the potential to hold up to four different radiators at the same time. So, needless to say, you have a lot of potential for liquid cooling in this case.

The Node 804 is a micro-ATX case (it can hold mini-ITX motherboards as well) and it can hold graphics cards up to 320mm long and if you want to opt for an air CPU cooler over liquid cooling, you can install heatsinks as tall as 160mm.

In the end, if you’re looking for a well designed small form-factor cube-style case that has plenty of features for liquid cooling, then the Node 804 is likely an option you’ll want to check out.

8. Cooler Master MasterCase H100

Honorable mention #3

Cooler Master MasterCase H100
  • Max GPU Length: 210mm
  • Max Cooler Height: 83mm
  • Micro-ATX, Mini-ITX
  • Black & White

Our Rating: 8.1/10

Check Price on Amazon

Finally, we have the Cooler Master MasterCase H100. The MasterCase H100 could also be considered as the best value option for cube-style cases as it does come in a bit under $100 and it has some features that might make it a better option for you when compared to the V21.

The MasterCase H100 can hold graphics cards as long as 210mm. For GPUs, that doesn’t give you a whole lot of options and you’ll be forced to use a low profile graphics card. But, if you’re looking to build as small of a PC as possible, you probably already expected that.

The H100 also has a CPU cooler height restriction of 83mm. That will limit you to low profile air coolers or a 120mm or 140mm AIO to cool this system.

While the H100 is quite a bit more limited in terms of space, its large 200mm fan on the vented front panel will help provide excellent airflow. And, the built-on handle at the top makes the H100 a great option for anyone who is looking to build a portable desktop.

Ultimately, if you have a moderate budget and you’re looking to build a very small system—and you don’t mind settling for the lower performance that will come from being restricted by this case’s GPU clearance—then the H100 is worth checking out.

If you want more room to house a higher-end system, though, and you don’t mind getting a little bit bigger case to do so, then the V21 is probably the better choice for you.

Is a Cube Style Computer Case for You?

While cube-style cases often come in more compact designs, they still are able to offer the main features that you’ll need in order to build a high-end system (they’ll work for budget-friendly gaming PCs as well). They can accommodate full-size graphics cards and air coolers, have a good range of options for airflow and liquid cooling and can look pretty cool, too.

In the end, cube-style PC cases won’t be for everyone, but if you are someone who likes the boxy-type of design, then the options listed above are probably right up your alley.
