Should You Buy the Jonsbo N4, N3 or N2 for your NAS DiY Build?

Building your NAS has inarguably become easier in recent years, thanks in large part to considerably more tailored and NAS-designed components arriving on the market that allow users to take a lot of the guesswork out of building a private cloud and network server from scratch. Although a lot of improvements and innovations have occurred in power-efficient SoC/Mobile CPUs and the miniaturization of technology, when it comes to actual NAS enclosures/cases – it’s actually a much less populated market than you might think. NAS cases are not really the same as traditional PC cases – designed with a greater focus on storage capabilities, hot swapping storage when needed, engineered for 24×7 use and designed to house the NAS-focused CPU+MoBo combos that have rolled out from brands such as ASrock, Topton, CWWK, Minisforum and more. Indeed, arguably one of the most popular brand’s in the market for NAS enclosures is Jonsbo, with its growing range of NAS-designed enclosures. Now that its fourth iteration has rolled out, the Jonsbo N4, I thought it time to find out what the main differences are between their three most popular NAS cases right now, the Jonsbo N2, N3 and N4. Each one has its strengths and weaknesses, ranging from scalability and day 1 storage, to motherboard compatibility and cooling systems. So, let’s compare the Jonsbo N4 vs N3 vs N2 and help you decide which one is best for you and your data!

It supports up to 6 3.5″ HDDs, positioning it between the N2 and N3 in terms of storage capacity but makes a distinct statement with its unique material choice and aesthetic. The N4 also supports a slightly larger CPU cooler height than the N2, up to 70mm, but less than the N3, balancing between compact design and cooling efficiency. Its cooling strategy is centered around a single built-in 120mm fan, ensuring that despite its capacity for larger motherboards, thermal management remains a priority. Through these nuanced differences in storage capacity, motherboard support, CPU cooler height, and cooling strategies, the Jonsbo N2, N3, and N4 enclosures offer tailored solutions for a range of user requirements, from compact, efficient setups to more expansive, versatile builds.

Jonsbo N3 vs N2 vs N4 – NAS Size and Physical Footprint

The Jonsbo N2, N3, and N4 NAS cases exhibit a thoughtful progression in physical size to accommodate varying user needs and preferences. The N2, the most compact of the trio, measures 222.5mm in width and depth, standing 224mm tall. This square-like dimension underscores its design for efficiency and minimal spatial footprint, ideal for users seeking a space-saving solution without compromising on storage capacity, with room for up to five 3.5″ HDDs. In contrast, the N3 slightly expands on this design philosophy, with dimensions of 233mm by 262mm by 298mm (WxDxH), thereby offering a larger internal volume. This additional space is leveraged to support up to eight 3.5″ HDDs, catering to users with greater storage needs while still maintaining a relatively compact form factor suitable for small office or home environments.

Model	Dimensions (WxDxH) mm	Max. CPU Cooler Height (mm)	Cooling System	Ventilation
N2	222.5 x 222.5 x 224	65	120x15mm fan *1 (built-in)	Side panels, top, rear
N3	233 x 262 x 298	130	100x25mm *2 (optional), 80x25mm *2 (built-in)	Side, back, ventilated front panel
N4	286 x 300 x 228	70	120mm *1 (built-in)	Side panels, top, rear, wooden front panel

Moving further up in size, the N4 distinguishes itself with dimensions of 286mm by 300mm by 228mm (WxDxH), making it the widest and deepest, yet not the tallest among the three. This layout is indicative of its design to accommodate both ITX and M-ATX motherboards, providing flexibility for users who may require more expansive motherboard support. The increased width and depth also facilitate an enhanced cooling solution and additional drive bays, accommodating up to six 3.5″ HDDs. Despite its larger size relative to the N2 and N3, the N4’s design remains conscious of space efficiency, striking a balance between accommodating more powerful hardware and maintaining a form factor that is still manageable within a variety of settings. This gradation in size across the Jonsbo NAS case lineup reflects a deliberate approach to meet diverse user requirements, from the most space-conscious to those needing a broader scope of hardware support and cooling efficiency.

Jonsbo N2 vs N4 vs N2 – Storage Capacity

The storage capacity of the Jonsbo N2, N3, and N4 NAS cases varies to cater to different user demands, reflecting a clear gradation in terms of available drive bays for HDDs and SSDs.

The N3, on the other hand, extends the ventilation scheme to include vents on the sides, back, and notably, a ventilated front panel. This comprehensive approach to airflow management ensures that cool air can be drawn in from the front and expelled through the side and rear vents, creating a constant flow of air through the chassis. The ventilated front panel not only contributes to the cooling efficiency but also adds to the case’s visual identity, merging functional design with aesthetic considerations. The ability to intake air from the front is particularly beneficial for systems with multiple drives, as it helps to mitigate heat buildup around the storage bays, maintaining optimal performance of the drives and other internal components.

The N4 case adopts a similar ventilation strategy to the N2, with vents on the side panels, a large top vent, and rear ventilation, ensuring ample airflow through the case. However, it distinguishes itself with a wooden front panel that covers half of the front, adding a unique aesthetic touch while still allowing for air intake through the lower half of the front panel. This design choice strikes a balance between form and function, offering effective cooling by combining the benefits of the N2’s ventilation pattern with a stylistic differentiation. The wooden panel adds a touch of elegance and natural texture to the case, setting it apart visually from many other NAS and PC cases on the market, without compromising on the thermal management aspect.

Across all three models, the use of rubber pull handles on the drive bays instead of trays not only simplifies the installation and removal process but also reduces vibration transmission, contributing to quieter operation. This design choice reflects a thoughtful consideration of usability and noise reduction, further enhancing the user experience.
