Dimension comparison
Design and Aesthetics
The HAVN HS 420 features a unique hybrid design with a heat-formed UniSheet glass panel that minimises distortion, providing a clear view of your components. In contrast, the CORSAIR 3500X showcases a wraparound glass aesthetic that enhances its visual appeal. While both cases are designed to highlight your hardware, the HAVN's design focuses on an innovative curvature, whereas the Corsair opts for a more traditional all-glass look. The HS 420's sleek design aims for modernity, while the 3500X emphasises a classic elegance, making them both attractive choices for any build.
Cooling Performance
The HAVN HS 420 offers excellent cooling capabilities, supporting up to eleven 140mm fans and accommodating three 420mm radiators, making it ideal for custom water cooling setups. On the other hand, the CORSAIR 3500X can fit up to ten 120mm fans, which is slightly less than the HAVN. However, it still provides robust cooling options with side, roof, and PSU mounting points. While both cases prioritise airflow, the HAVN excels in expandability for cooling, making it suitable for high-performance builds that require extensive thermal management.
Cable Management
Effective cable management is crucial for a clean build, and the HAVN HS 420 excels in this area with its unique SimpliCable system, featuring integrated cable channels and a PWM fan hub. This design promotes neat routing and organisation, enhancing both aesthetics and airflow. Conversely, the CORSAIR 3500X includes removable tempered glass panels that make accessing your cables easier but does not highlight a specific management system. While both cases provide some level of cable management, the HAVN offers a more structured approach, making it easier for users to maintain an orderly setup.
Compatibility and Flexibility
The HAVN HS 420 is designed to be highly versatile, with a customisable interior that supports storage, fans, radiators, and even portable displays, thanks to its included VESA mount. Its adjustable GPU bracket can accommodate graphics cards of any size, enhancing flexibility for diverse builds. The CORSAIR 3500X, supporting motherboard form-factors from Mini-ITX to EATX, also offers a good level of compatibility. However, it lacks the extensive customisation options found in the HAVN. If you're looking for a case that offers exceptional adaptability, the HAVN HS 420 might be the better choice.
Pre-Installed Cooling Solutions
The CORSAIR 3500X comes with three pre-installed RS120 ARGB fans, which provide immediate cooling and attractive lighting without additional purchases. This feature allows users to enjoy high-performance cooling right out of the box. In contrast, the HAVN HS 420 does not specify any pre-installed fans, placing the onus on the user to configure their cooling solution. While the absence of pre-installed fans in the HAVN may appeal to those wanting a custom setup, the convenience offered by the Corsair's pre-installed fans cannot be overlooked, especially for newcomers to PC building.
Pricing and Value
The HAVN HS 420 is priced at £199.99, reflecting its advanced features and extensive cooling capabilities. In stark contrast, the CORSAIR 3500X is significantly more affordable at £84.98. This price difference can be attributed to the varying features and customisation levels of each case. While the HAVN provides sophisticated cooling and cable management that may justify its higher price, the Corsair offers exceptional value for those who desire a solid case without breaking the bank. Ultimately, your choice will depend on your budget and specific needs.
User Experience and Accessibility
Both cases are designed to provide a user-friendly experience, but they cater to different preferences. The HAVN HS 420's innovative design and focus on cable management make it appealing for users who prioritise aesthetics and organisation. Meanwhile, the CORSAIR 3500X allows for easier access with its removable tempered glass panels, making it simpler to build and upgrade. If you value accessibility for frequent modifications, the Corsair case may be more suitable. However, if you prefer a well-organised build with excellent cooling capabilities, the HAVN case stands out.
Which should you buy?
Choosing between the HAVN HS 420 and the CORSAIR 3500X ultimately depends on your individual priorities and budget. If you seek advanced cooling options, extensive customisation, and superior cable management, the HAVN HS 420 at £199.99 is an excellent investment. However, if you're looking for a cost-effective solution that provides solid cooling features without the need for extensive modifications, the CORSAIR 3500X at £84.98 presents great value. Consider your specific requirements and budget to determine which case aligns best with your PC building goals.
