Price Comparison
The HAVN HS 420 is priced at £199.99, significantly higher than the Lian Li O11 Dynamic Mini V2, which retails for £84.99. This difference of £115 reflects the distinct features and target audiences of each case. The HAVN HS 420 is aimed at users seeking extensive cooling options and customisation, while the Lian Li O11 caters to those who prefer a compact case without sacrificing hardware capabilities. The value proposition of each case aligns with its price point, making the Lian Li an attractive choice for budget-conscious builders.
Design and Aesthetics
When it comes to design, the HAVN HS 420 features a distinctive hybrid design with a heat-formed UniSheet glass panel that provides a sleek view of internal components. In contrast, the Lian Li O11 Dynamic Mini V2 adopts a minimalist aesthetic with a clean look, utilising smart cable management to keep clutter at bay. The HAVN's innovative curvature may appeal to those who prioritise visibility of their hardware, while the Lian Li's straightforward design is perfect for users who appreciate simplicity and elegance in a compact form factor.
Cooling Performance
Cooling performance is a standout feature of the HAVN HS 420, supporting up to eleven 140mm fans and accommodating three 420mm radiators. This extensive cooling capability is ideal for high-performance builds requiring optimal thermal management. On the other hand, the Lian Li O11 Dynamic Mini V2 supports up to nine fans and two radiators, which is impressive for a mini case. While both cases offer efficient cooling solutions, the HAVN HS 420 is better suited for users intending to build a powerful system with multiple cooling options.
Cable Management
The HAVN HS 420 excels in cable management with its unique SimpliCable system, which includes a PWM fan hub and integrated cable channels for neat routing. This feature allows for a clean and organised build, enhancing the overall aesthetic of the setup. Conversely, the Lian Li O11 Dynamic Mini V2 also prioritises cable management, providing mounts and straps, along with support for back-connected motherboards. Both cases offer efficient solutions, but the HAVN's dedicated system might provide a more user-friendly experience for those who value tidy builds.
Customisation Options
Customisation is a key strength of the HAVN HS 420, featuring a three-way adjustable GPU bracket that accommodates graphics cards of any size, along with space for storage, fans, and even portable displays with a VESA mount. This level of flexibility is ideal for builders who want to tailor their systems extensively. Meanwhile, the Lian Li O11 Dynamic Mini V2 offers flexible GPU installation options, allowing for both horizontal and vertical mounting. However, the HAVN's broader array of customisation features gives it an edge for users looking to personalise their setups extensively.
Size and Footprint
The HAVN HS 420 is a mid-tower case, providing ample space for components, while the Lian Li O11 Dynamic Mini V2 is designed as a small form factor case. Despite its compact nature, the Lian Li offers sufficient room for full-size hardware, making it a practical choice for users with limited space. The HAVN's larger size may appeal to those planning to build more extensive systems, but for users constrained by space, the Lian Li’s mini footprint is a significant advantage.
Build Quality
Both cases exhibit solid build quality, but their construction philosophies differ. The HAVN HS 420 features a tempered glass panel designed to minimise distortion, providing a clear view of the internal hardware while also ensuring durability. The Lian Li O11 Dynamic Mini V2, known for its clean design, also integrates high-quality materials and thoughtful engineering to prevent overheating and dust accumulation. Each case aims to provide a robust environment for components, but the HAVN’s focus on innovative design may attract users looking for a more striking appearance.
Which should you buy?
Choosing between the HAVN HS 420 and the Lian Li O11 Dynamic Mini V2 ultimately depends on your specific needs and preferences. If you're after extensive cooling options and customisation features, the HAVN HS 420, priced at £199.99, stands out with its superior support for cooling components and flexible build options. However, if you prefer a compact case that doesn't compromise on performance and comes at a more affordable price of £84.99, the Lian Li O11 Dynamic Mini V2 is an excellent choice. Both cases serve different user needs, making them strong contenders in the PC case market.
