Today, we’re going to focus on smaller cases in the small form factor segment, mainly models meant for mini ITX motherboards.
The mini ITX format hasn’t historically been anywhere near as popular as the ATX or even microATX motherboards. However, recent innovations have made them a much better choice. You can learn more in our PC case sizes explained guide.
At A Glance:
In this guide, we’ll go over ten different cases so that you’ll be more likely to find something that works right for you.
We’ll cover everything ranging from a case’s specifications to whether or not a product will be ideal for a first-time builder.
By the end of this guide, you’ll probably have found the perfect small form factor case for your build.
Top 10 Best Mini ITX Cases
1. Thermaltake Core V1
- Comes with a 200mm cooling fan
- Interchangeable side panels for the perfect look
- Supports 3.5” and 2.5” drives
- Dual chamber design improves cooling
- Equipped with a dust filter for the PSU fan
- Supports an expansion card of up to 285mm
Thermaltake’s Core V1 is a favorite in the SFF (small form factor) community. This is because of its support of larger components and how approachable it is for beginners.
While many cases designed for ITX motherboards will require a different approach, building in a Core V1 is much like working with an ATX case.
This case comes with a 200mm cooling fan. However, this may have to be removed if you’re looking to fit in a long GPU.
In addition, there is a dust filter on the PSU fan. As a result, there is one less way that the dust can get into your machine.
The Core V1 takes full advantage of a dual chamber design. This keeps the heat from the GPU isolated from the PSU and many of the cables, improving airflow.
2. NZXT H200i
- Steel construction for added durability
- Features a built-in RGB fan controller
- Comes with two fans and pre-installed RGB strips
- Features cable channels and straps already installed
- Ready for both air and liquid cooling
- Available in four different color combos
The H200i from NZXT is an excellent choice of ITX case for buyers who want their computer to look good and don’t mind sacrificing a bit of portability for it.
As a result of the all-steel construction frame, means that it’s more durable than many competing models that use plastics.
In addition, this case comes with an RGB fan controller. This isn’t something that you would expect to see in a case that’s so reasonably priced.
While this case may be a little more expensive than competing models, cases with fan controllers can easily get up to 150-dollar range.
There are also RGB strips and two case fans that come pre-installed. Therefore, you won’t have to go out of your way to find your own.
This model is the baby brother to the H500i which featured in our 10 best tempered glass case guide.
3. Corsair Crystal 280X RGB
- Comes included with two Corsair RGB fans
- Features three tempered glass panels
- Dual chamber design for better cooling and cable management
- Supports up to two 3.5” or three 2.5” drives
- Dust filters on most vents
Unlike the previous case, which incorporated RGB strips, the lighting in this model is limited to the two Corsair fans that come included.
As you would expect from a reputable company like Corsair, this case is well-made. It also features a logical layout that makes it simple to build in.
Like many of the best ITX cases around, this one features a dual chamber design that helps keep the GPU’s heat isolated from a lot of other components.
In addition, this model also features near-complete coverage with dust filters. This will help reduce the amount of time you spend cleaning it with compressed air.
The inclusion of three tempered glass panels means that you can see the interior from nearly any angle.
If you’re looking for an attractive case that comes with RGB fans, this one is right for you.
4. In Win A1
- Integrated RGB base for a unique look
- Comes included with an 80 Plus Bronze Certified 600W PSU
- Tempered glass panel for interior viewing
- Wireless charging area on the case’s top
- Supports GPUs up to 300mm long
The SFF community loves In Win for their brilliantly small case designs. Their A1 model is one of the favorites due to its GPU support over the company’s smaller Chopin model.
This case can fit an expansion card that is up to 300mm, which is enough for all but the longest cards.
One of the most impressive features that come included with the A1 case is the ability to wirelessly charge any Qi-enabled device on the top surface.
In addition, we loved the transparent RGB base that gives this case the impression of floating.
You can find this model available in both black and white, allowing you to further customization.
If you need something compact and high-quality, this case is an excellent choice.
5. NZXT Manta
- Available in three colors or windowless
- Unique curved design
- Structurally reinforced steel construction
- Comes included with fans to save you money
- Cutouts for managing cables
- Included dust filters
The Manta is somewhat different from the other cases that we have reviewed due to its curved sides.
While the curves may take up a little more space, they also have an advantage beyond looking good. Since the sides of the case bulge out, you’ll have more room for cable management.
You have a choice of three different colors with a window or a stealth black without a window. This allows you to pick the look that works for you.
The included case fans are powerful enough to keep the system running cool. Although it may need extra cooling when overclocking a GPU or under heavy load for hours at a time.
In addition, there are full-sized dust filters that you’ll find on the front and top of this case to help keep the internals clean.
6. Phanteks Evolv Shift X – Slim Mini ITX Case
- Dual tempered glass panels
- Designed to have a smaller footprint than other cases
- Comes with two 140mm case fans
- Supports GPUs up to 529mm
- Can hold two 3.5” drives or four 2.5” drives
- Easy to build in
Another relatively unique case is the Evolv Shift X from Phanteksp. This model is meant for users who want a computer with a small footprint.
Instead of making this case wider or longer, Phanteks decided to create an ITX case that was taller. This layout makes it an interesting case to build in.
We wouldn’t recommend this case for first-time builders because of how different the process is when compared to other cases. Nonetheless, this model is remarkably easy to assemble.
All four side panels come off, and the top hinges open. This gives you access to everything without having to reach through tiny spaces.
This case can also support the largest GPUs (up to 529mm), and you have a choice of either two 3.5” hard drives or four 2.5” HDDs or SSDs (learn more about SSD vs HDD for gaming here).
7. Cooler Master Elite 110 – Smallest Mini ITX Case
- Mesh panels for improved airflow through the case
- Compatible with GPUs up to 210mm
- Supports both 2.5” and 3.5” drives in various combinations
- Max CPU cooler height of 76mm
- Also supports an AIO
The Cooler Master Elite 110 is a relatively basic ITX case that doesn’t come with too many bells and whistles. But this isn’t necessarily a bad thing.
If you need something simple and affordable, but is well-made and reliable, then this model is an excellent choice.
The frontal panel is made into a mesh to ensure that the machine gets as much airflow as possible. In addition, it even supports water cooling which is rare for a mini ITX case.
Keep in mind that this case only features a CPU cooler height of 76mm, so don’t expect to get any big air coolers to fit inside of it like some of the ones in our top i7-9700k CPU coolers guide.
Also, this model doesn’t support larger GPUs, as the maximum size is 210mm. Therefore, you’ll be limited to a more compact card, restricting your options.
8. Thermaltake Core P1
- Unique open-frame design
- Ideal for liquid cooling due to the lack of side panels
- 5mm tempered glass window is durable
- Modular design helps simplify the build process
- Can be used in three ways: horizontal, vertical, or wall-mount
The Core P1 from Thermaltake is something truly different. It’s a breath of fresh air to small form factor cases.
Most other cases will seem like derivatives of each other. However, you won’t find too many similar models to this that haven’t been custom-made by the builder.
The open frame design of this case means that you can see all of the components. So, if you’re a fan of precise cable management and good-looking parts, then you’ll love this case.
The lack of side panels also means that you’ll have superior airflow, so cooling won’t typically be an issue.
Also, you can choose how you position this case, as it has the basic vertical setup, a horizontal layout, and it can also be mounted to a wall.
9. Fractal Design Nano S – Quietest Mini ITX Case
- Sound dampening design helps reduce fan noise
- Supports up to four storage drives
- Comes included with two case fans
- Removable dust filters are easy to clean out
- Supports ATX power supply units
Fractal Design is known for its excellent small form factor cases. Their Node 202 model is a favorite in the community, so the Nano S has a lot to live up to.
Thankfully, this product continues to uphold the company’s pedigree by being one of the quietest ITX cases on the market.
The Nano S is made using sound dampening panels and ModuVent technology. Both of which work together to ensure that you hear as little fan noise as possible.
This case even comes with two Dynamic Series fans which are rated to be quieter than many of the other case fans on the market.
As with many other Fractal Design cases, this one comes with removable dust filters. This will keep the interior of your system clean.
10. Silverstone SG13
- A choice between mesh or solid frontal panel
- Available in two colors
- Supports full-sized GPUs
- Supports either 1 x 2.5”/1 x 3.5” or 3 x 2.5” storage drives
- Compatible with ATX PSUs
Silverstone is another big name when it comes to compact PCs. Their SG13 case is part of their Sugo Series, which is a favorite amongst gamers.
This is due to the support of full-size GPUs across the entire series, and the SG13 is no different.
In addition, you can also fit in an ATX power supply. Which makes this case an excellent option for anyone that is downsizing from a full-size rig.
When buying an SG13, you’ll have the choice of either a solid frontal panel or one that is made of mesh. The former will reduce noise while the latter will provide extra airflow.
Overall, the SG13 is easy to build in, and it supports larger components than many other models, making it a great choice for a gaming system.
As small form factor PCs become more popular, the number of ITX-compatible cases will only start to increase. We hope that this guide has helped you pick out the right case for your next computer build.
