Smallest Mini ITX Cases

Smallest ITX Casings for Mid-High-End Builds.

A case is like a house to the PC components and sometimes you just don’t want a super-big case for obvious reasons. That is why the concept of mini-ITX cases exists. The mini-ITX cases are the smallest cases on the market and can host the mini-ITX motherboards. 

A particular thing to note about mini-ITX cases is that you will have to buy compatible components to install them in such a small case. That is why there are power supplies, motherboards, and graphics cards that are designed specifically for mini-ITX cases. The advantage of mini-ITX cases is that you can easily place such a PC in your TV lounge and can even use it as a portable computer if you ever feel the need to move here and there. 

Making a mini-ITX system can usually cost more than making a standard system and yet the performance of a mini-ITX system would most likely be lower than a standard-sized system with similar components. The reason is that there is less airflow in a mini-ITX system and the components like the processor and graphics card downclock themselves when they get thermal-throttled.

If you want a Unique looking casing for your Mini ITX to build and are not afraid to splash the cash then you should consider the InWin A1 Black casing. InWin Casings have been making a lot of rounds in the PC community and has become quite mainstream due to their out-of-the-box design.

Even though there is no top and front fan mounted the casing still manages to keep your temps down. Instead of at the top and front, the casing comes with fans that are hooked at the side and bottom. It supports a fan up to 120mm in size. This particularly helps in keeping the GPU cool as it’s placed near the bottom close to the fans. For further optimizing the airflow there is also an option of placing a rear exhaust fan that will chuck the hot air out. Overall, the airflow is great for the casing and the probability of the PC components throttling thermally is very low.

The casing comes with built-in RGB lighting and also a transparent stand which makes it so that the case is floating in midair. There is also a Qi wireless charger in the casing which will let you charge your smartphone.

The Skyreach 4 Mini is one of the smallest Mini ITX casings on the market right now. It has a volume of 5 liters and its small size factor makes it quite portable as it can easily fit inside a bag pack so you can carry your PC around if you have to.

You can fit a GPU with a length of 210 mm so you can easily hook up a high-end card like the RTX 2070 or even a Zotac 1080 Ti mini. You can fit up to 2.5 drives. There is a compromise on CPU cooling due to its compact size. However, you can hook in a cooler like the Noctua L9i or L9a which is capable of cooling an i5 or a Ryzen 5 processor. The case has been designed with a strong lightweight material that adds to its portability factor. The majority of the PSUs will not fit inside the case and with a mini ITX build, you don’t need a lot of power. So, it comes with a specially designed PSU, the HDPlex 400AC which will look after all your needs.

The only downside to the casing is that it’s on the expensive side. But, the features that you’re getting in return such as the 5 liters volume, its extensive portability and the ability to even house a GPU like the RTX 2070 make it quite worthwhile and must be commended for its design.


The Pros:

  • Great minimalist design.
  • Exceptional thermal performance.
  • Good for mini-ITX builds.
  • Bundled with PCIe 4.0 riser cables.

The Cons:

  • There are no IO options on front.

They say that save the best for the last and that is what I have done with the case that I am going to recommend now. The Louqe Ghost S1 is the best Mini ITX casing in the market as it excels in all three criteria of a casing. It has got ample space inside, has got that premium build quality and it looks phenomenal as well.

The case is made from extruded aluminum panels instead of sheet metal, which gives the casing a more premium look. The interior of the casing has been designed in a sandwich-style layout as the motherboard and PSU can be fit in one compartment while the GPU can be fit in another. The interior has a volume of 8.2 liters which is ample space for hosting a Mini ITX build. There is a tophat vertical extension present which can be used to house different components such as case fans, a radiator, and even storage drives should you feel the need to which makes the case modular. The tophat can be added to the bottom of the casing as well in case you have already maxed out the top of the casing with cooling solutions. You can add your hard drives at the bottom as the casing has got plenty of space and you won’t need to upgrade.

The casing comes in an all-black color and the only downside to this casing is that you will need to splash quite a lot of cash to buy so make sure you have the credit in your account. Nonetheless, it is the best Mini ITX case on the list and you won’t be disappointed.
