Overview of the HAVN HS 420 and Lian Li A3

The HAVN HS 420 is a mid-tower PC case priced at £199.99, while the Lian Li A3 is a compact micro ATX cabinet retailing for £69.99. These two products cater to different user needs, with the HAVN HS 420 designed for high-performance builds and extensive cooling options, whereas the Lian Li A3 offers a more elegant, space-saving design suitable for smaller systems.

The HAVN HS 420 features a dual-chamber layout that supports up to eleven 140mm fans and has the capacity for three 420mm radiators. In contrast, the Lian Li A3 can accommodate up to ten fans and a 360mm radiator, making it less versatile for large cooling setups but ideal for compact builds.

Design and Aesthetics

The HAVN HS 420's design focuses on functionality and cooling efficiency, featuring a heat-formed UniSheet glass panel that offers a clear view of its interior. This innovative design minimises distortion, enhancing the visual appeal of your components. The case's black hybrid design adds a modern touch that complements gaming setups.

On the other hand, the Lian Li A3 stands out with its refined wooden accents, giving it a sophisticated appearance. The compact design, measuring just 26.3 litres, makes it a stylish option for those looking to save desk space without sacrificing aesthetics. While both cases are visually appealing, the choice ultimately depends on whether you prefer a sleek, modern look or an elegant wood finish.

Cooling Performance

Cooling performance is a key consideration for gamers and PC builders alike. The HAVN HS 420 excels in this area, supporting up to eleven 140mm fans and the installation of three 420mm radiators. This extensive cooling setup is well-suited for high-performance components, ensuring optimal temperatures during intensive gaming sessions or heavy workloads.

Conversely, the Lian Li A3 supports up to ten fans and a 360mm radiator. While this is adequate for most micro ATX builds, it may not provide the same level of performance as the HAVN HS 420 in extreme scenarios. However, for users with moderate cooling needs, the Lian Li A3 offers sufficient airflow and cooling capabilities in a more compact form factor.

Compatibility with Components

The HAVN HS 420 is designed to accommodate a wide range of components, including a three-way adjustable GPU bracket that fits graphics cards of any size. This flexibility is perfect for users looking to build high-end gaming rigs. The case also supports ample storage options and has dedicated space for custom water cooling setups, making it a versatile choice for enthusiasts.

In contrast, the Lian Li A3 supports micro ATX and Mini-ITX motherboards, along with PCI expansion slots for four graphics cards. It can house graphics cards up to 415mm long, which is impressive for its size. However, the limited space means that it may not be suitable for larger components or extensive upgrades, making it more suitable for casual users or those with less demanding setups.

Cable Management

Effective cable management can greatly enhance the aesthetics and airflow of a PC build. The HAVN HS 420 features a unique SimpliCable cable management system that includes a PWM fan hub and integrated cable channels. This design facilitates neat routing, allowing builders to maintain a clean and organised interior. The ease of use in managing cables is a significant advantage for those who value a tidy build.

On the other hand, the Lian Li A3 does not emphasise cable management to the same extent. While it provides the basic functionality for routing cables, it lacks the dedicated systems found in the HAVN HS 420. Users who prioritise a sleek appearance may find the HAVN's cable management system more appealing.

Price Point

The price difference between the two cases is substantial, with the HAVN HS 420 priced at £199.99 and the Lian Li A3 available for £69.99. This makes the Lian Li A3 a more budget-friendly option, appealing to users looking for a stylish yet functional case without breaking the bank.

However, the higher price of the HAVN HS 420 reflects its advanced features and superior cooling capabilities. For users seeking a high-performance case that supports extensive customisation and cooling options, the investment may be justified. The choice here largely depends on your budget and specific needs for your PC build.

Target Audience

The HAVN HS 420 is geared towards PC builders who require a spacious, high-performance case with extensive cooling options. Gamers and content creators who push their hardware to the limits will benefit from its features, making it a suitable choice for those looking to build a powerful workstation or gaming rig.

Conversely, the Lian Li A3 is designed for users who appreciate aesthetics and need a compact solution for their micro ATX builds. It caters to casual gamers, office setups, or anyone who values a refined appearance in a smaller form factor. The choice between the two will depend on whether performance or compact elegance is the priority.

Which should you buy?

Choosing between the HAVN HS 420 and the Lian Li A3 ultimately depends on your specific needs and preferences. If you require extensive cooling options, component compatibility, and advanced cable management, the HAVN HS 420 is the superior choice at £199.99. However, for those seeking a stylish, compact case at an affordable price of £69.99, the Lian Li A3 is an excellent option that meets basic requirements without compromising on aesthetics. Consider your needs carefully to make the best decision for your PC build.
