10 Best Mini ITX Cases UK 2024 | NZXT, Corsair and More

Cooler Master are well known in the world of PC building as they manufacture some of the best heat sinks and air coolers in the world. This case is no different with space for liquid cooling radiators and up to seven fans in total. 

The MasterBox is a great all-around choice but is perhaps best suited to budget gaming builds as it can house GFX cards up to 330 mm in length and supports both mini-DTX and mini-ITX motherboards. If you're looking to keep your components running cool, then you can't go wrong with Cooler Master.

This case's two chambers, a front and rear, will keep even the most resource-intensive graphics cards cool – and as well as the two RGB fans included, there's room for up to six in total. Corsair's Direct Airflow Path design also means that this case can handle the most powerful CPUs and GPUs around.

There are also dust filters on practically every opening to ensure that your system looks great once it's in place. Combined with the tempered glass side and RGB lights, it looks incredible when all systems are firing.

The H210 is one of the best options around if you're looking to fit a high-end system into a compact and aesthetically pleasing case without breaking the bank. It's suitable for both air-cooled and liquid-cooled systems, and there's plenty of space inside for GFX cards up to 325 mm. 

With its large tempered glass panel, it's easy to see what you're doing when building your PC, plus it allows you to create any look you want in terms of lighting. There are also plenty of options for cable management to keep everything well organised. 

Just like its older sibling, the Core V1 from Thermaltake is divided into two chambers to allow for the most air circulation possible while keeping your cables neat and tidy. It's full of air holes in order to keep one of the smallest cases on our list as cool as possible.

If you're looking for a small work PC that doesn't take up too much space on a desk, then this is a great option. We'd also recommend this as a media centre if you're after something to tuck away in a cabinet or TV stand.

At first glance, you may be forgiven for thinking that you're looking at an option that's going to cost upwards of £100 thanks to the huge eye-catching RGB light on the front of this case. 

However, thanks to its tall design, it's capable of accommodating the larger CPU coolers (184 mm) and GFX cards up to 347 mm in length, which is the best on our list in terms of interior space. Like others, the hinged tempered glass panel opens up for easy access which is always a nice touch.

The Thermaltake V21 is a modular case, which means that it's divided into two chambers in order to keep your cables separated from your components. In turn, this will maximise cooling whether you opt for fans or liquid cooling.

There is plenty of flexibility thanks to the modular design, so whether you want to include some extra hard drive space for a media centre or fit in a high-end graphics card, you're able to pick and choose the layout which is optimal for your build.

Being the premier maker of gaming accessories in the world, it's no surprise that Razer's cases are made with gamers in mind. The Tomahawk is fully compatible with AIO or custom liquid cooling systems, has plenty of space for air circulation, and can accommodate GFX cards up to 320 mm long as well as those thicker cards that require three expansions slots.

There aren't any cooling options included with the case so you'll need to have some experience in PC building and be aware of which fans, or liquid cooling, you want to install. It's also worth noting that, while expensive, it's most definitely good quality and the two tempered glass swivel doors make accessing the innards a breeze.

Thanks to its incredibly sleek and thin design, there's no better option than this if you're after something to sit exclusively underneath a TV. This wouldn't look out of place next to a DVD player or smart TV box.

You may have noticed the lack of cooling options included with this case, so you'll want to make sure that you're not installing any components that run too hot unless you plan on adding your own fans. Luckily, thanks to the smart thermal interior design and ample ventilation, a simple media centre shouldn't have too much trouble.

If you're looking for a unique and small form PC that you want to hook up to a living room TV to act as a home media centre, then this case would make a great choice. As you can see, it doesn't look too dissimilar to a router or modem.

You can stand it on its end on a shelf next to your WiFi router, or place it flat underneath a television where you'll barely notice its presence, but its small size means that it's not suited for more powerful builds due to the lack of space, and therefore air circulation, inside.

After a cheap case for a simple work PC or a media centre? You won't find one much more compact than this offering from CiT. It's even small enough to mount onto the back of a monitor with the included VESA mount.

As a more budget-friendly option, this case doesn't have the most premium feel and there are some reports of the CD slot not quite lining up properly, so it's not something we'd recommend if you're planning on adding a DVD drive.
