Overview of the HAVN HS 420 and Lian Li O11D EVO
The HAVN HS 420 is priced at £199.99, while the Lian Li O11D EVO comes in at a more affordable £138.99. Both cases cater to gamers and PC builders looking for quality mid-tower options, but they each offer distinct features that appeal to different user preferences.
The HAVN HS 420 stands out with its dual-chamber design, enhancing airflow and cooling efficiency. In contrast, the Lian Li O11D EVO is known for its modularity and customisation, making it a versatile choice for users who may want to tweak their setups over time.
Cooling Performance
Cooling is a critical aspect of any PC build, and both cases excel in this area. The HAVN HS 420 supports up to eleven 140mm fans and can accommodate three 420mm radiators, ensuring extensive options for custom water cooling setups. This impressive cooling potential makes it particularly suitable for high-performance gaming builds or intensive tasks.
The Lian Li O11D EVO also offers strong cooling capabilities, allowing for up to ten fans and various radiator sizes. This ensures that even the most demanding hardware remains cool during intense gaming sessions. While both cases provide excellent cooling options, the HAVN HS 420 has a slight edge due to its higher fan support.
Design and Aesthetics
In terms of design, the HAVN HS 420 features a heat-formed UniSheet glass panel that minimises distortion, providing a clear view of the components inside. This sleek design is not only visually appealing but also functional, allowing users to showcase their hardware effectively.
On the other hand, the Lian Li O11D EVO is designed with a highly customisable structure, including a reversible frame and movable motherboard tray. This level of flexibility allows users to personalise their build to suit their aesthetic preferences. Both cases are visually striking, but the HAVN HS 420's unique glass panel may appeal more to those prioritising aesthetics.
Cable Management
Effective cable management can significantly enhance the overall appearance of a PC build. The HAVN HS 420 features the Unique SimpliCable management system, complete with a PWM fan hub and integrated cable channels. This system ensures neat routing, which is essential for maintaining a clean and organised build.
The Lian Li O11D EVO also includes extensive cable management solutions, which are crucial for keeping cables tidy and out of sight. However, the HAVN HS 420's dedicated management system may offer a more user-friendly experience, particularly for those new to PC building.
Internal Layout and Space
When it comes to internal layout, the HAVN HS 420 provides a spacious environment for storage and cooling components. Its design includes a 3-way adjustable GPU bracket, allowing flexibility for graphics cards of any size. This adaptability is beneficial for users who may upgrade their GPUs in the future.
Conversely, the Lian Li O11D EVO supports a variety of motherboard sizes, including E-ATX, ATX, Micro-ATX, and Mini-ITX, making it a highly versatile option. With 455.7mm of GPU clearance, it can accommodate even large GPUs like the NVIDIA RTX 4090. While both cases offer ample space and flexibility, the Lian Li O11D EVO's support for multiple motherboard sizes may attract users looking for versatility.
Ease of Building
Building a PC can be daunting, but both cases aim to simplify the process. The HAVN HS 420's design is focused on ease of use, particularly with its cable management system. This means that even novice builders can achieve a neat and organised setup without too much hassle.
The Lian Li O11D EVO features a removable motherboard tray and fan brackets, which further streamline the building process. This attention to user experience can make a significant difference for those who may be building their first PC. While both cases are designed to facilitate easier assembly, the Lian Li O11D EVO's additional features may provide a more straightforward building experience.
Brand Reputation and Support
Brand reputation can play a vital role in the decision-making process when choosing a PC case. HAVN is newer in the market, offering innovative designs like the HS 420, which is gaining traction among PC enthusiasts. However, as a newer brand, it may not have the same level of established support and community as longer-standing brands.
Lian Li, on the other hand, has a well-established reputation for producing high-quality PC cases and components. Known for their durability and design, Lian Li products often come with robust customer support and a community of users who can provide assistance and share experiences. This reputation may be an important factor for buyers prioritising reliability and support.
Which should you buy?
Choosing between the HAVN HS 420 and the Lian Li O11D EVO ultimately depends on your specific needs and preferences. The HAVN HS 420, priced at £199.99, offers superior cooling potential, a unique design, and a user-friendly cable management system, making it an excellent choice for high-performance builds and those who value aesthetics.
Conversely, the Lian Li O11D EVO, at £138.99, is highly customisable and versatile, accommodating various motherboard sizes and ensuring an easier building process. Its well-established reputation also provides additional peace of mind.
If you prioritise cooling and design, the HAVN HS 420 is a worthy investment. However, if you seek flexibility and a more budget-friendly option, the Lian Li O11D EVO is likely the better choice.
