Overview of the PC Cases
The CORSAIR 3500X RS Reverse Fan ARGB Mid-Tower PC Case is priced at $79.99, while the JONSBO/JONSPLUS Z20 Black Micro-ATX Mini Tower PC Case is available for $99.99. This makes the Corsair model about 20% cheaper than the Jonsbo option. Both cases cater to different user preferences, with the Corsair focusing on aesthetics and cooling capabilities, and the Jonsbo emphasizing portability and compact design.
The 3500X features a striking wraparound glass aesthetic with three pre-installed ARGB fans for vibrant lighting and effective airflow. In contrast, the Jonsbo Z20, although smaller, offers a convenient detachable carrying handle, making it suitable for users who need to transport their systems frequently. Understanding these features can help you make an informed choice based on your specific needs.
Design and Aesthetics
In terms of design, the CORSAIR 3500X stands out with its panoramic glass panels that enhance the visual appeal of any build. The sleek, modern design is complemented by RGB lighting, appealing to gamers and PC enthusiasts who value aesthetics. The spacious interior allows for a clean build, minimizing cable clutter, which is a notable feature for those who prioritize presentation.
On the other hand, the JONSBO Z20 adopts a more utilitarian approach with its compact structure, measuring only about 20 liters in volume. Its robust steel panels combined with a magnetic dust filter make it a practical choice for users who prioritize functionality over flashiness. While it may not have the same level of visual flair as the Corsair, its straightforward design still has its charms, particularly for smaller setups.
Cooling Performance
Cooling capabilities are critical for any PC case, and the CORSAIR 3500X excels in this area. It supports up to 10x 120mm fans, ensuring ample airflow and cooling potential for high-performance builds. The inclusion of three RS120-R ARGB fans pre-installed is a significant advantage, providing both cooling and visual effects right out of the box.
Conversely, the JONSBO Z20 offers flexibility with its cooling options, supporting a 240mm AIO cooler and various fan configurations. It accommodates multiple fan sizes and offers a maximum GPU clearance of 363mm, making it a solid choice for users who prefer to customize their cooling solutions. While it may not match the Corsair's capacity, it still provides sufficient cooling for most builds, especially in its compact form factor.
Compatibility and Expansion
The compatibility of a PC case can determine how versatile and future-proof your build can be. The CORSAIR 3500X supports motherboard form factors from Mini-ITX to EATX, making it a highly flexible option for users planning to upgrade their systems over time. It is also compatible with reverse connection motherboards, which can enhance cable management and aesthetics, allowing for a cleaner build.
In contrast, the JONSBO Z20 is specifically designed to accommodate Micro-ATX motherboards. While this limits its compatibility compared to the Corsair, it still supports a variety of hardware configurations, including a side-mounted SFX power supply. For users who favor a compact setup and do not require larger motherboards, the Jonsbo offers sufficient expansion options without overcrowding the space.
Ease of Building
Building a PC should be a straightforward process, and here, the CORSAIR 3500X shines with its removable tempered glass panels that allow easy access during assembly. The thoughtful design ensures that users can manage their components without hassle, making it a great choice for both beginners and experienced builders alike.
The JONSBO Z20, while compact, also facilitates an easier building experience with its innovative design, including a removable PCI-E fixing piece. This feature optimizes the installation process for longer GPUs, which can often be a challenge in smaller cases. However, the compact nature of the Z20 may still pose some challenges depending on the complexity of the build.
Portability
Portability is a crucial factor for users who need to transport their PCs. The JONSBO Z20 has a distinct advantage here with its detachable carrying handle, allowing users to move their systems easily without the need for additional equipment. This feature makes it particularly appealing for gamers attending LAN parties or individuals who frequently relocate their setups.
In contrast, the CORSAIR 3500X, while not designed for portability, offers a more spacious build that may be cumbersome to transport. This is a point to consider for users whose setups will remain stationary versus those who value the ability to move their systems.
Price Comparison
The price difference between the two cases is notable, with the CORSAIR 3500X priced at $79.99 and the JONSBO Z20 at $99.99. This makes the Corsair model about 20% cheaper, which might be a deciding factor for budget-conscious consumers. While the Jonsbo offers unique features like portability, the additional cost may not be justified for all users, especially those who prioritize aesthetics and cooling performance.
Ultimately, the choice between these two cases may come down to whether the user values the extra features of the Jonsbo enough to warrant the higher price. Assessing your specific needs and budget can help clarify the best option.
Which should you buy?
Choosing between the CORSAIR 3500X RS and the JONSBO Z20 ultimately comes down to your specific needs and preferences. If you prioritize aesthetics, cooling performance, and flexibility in your builds, the CORSAIR 3500X is the superior choice at a more attractive price point of $79.99. However, if portability and a compact design are essential for your usage, the JONSBO Z20, priced at $99.99, offers convenient features that cater to those needs. Consider these factors carefully to make the right decision for your next PC build.
