The Jonsbo N4 NAS Case Review

Jonsbo N4 NAS Case Hardware Review – Technically ‘Jonsbo N2 and a Half’?

I think it would be fair to say that in the world of DIY NAS building, few brands have achieved a similar level of notoriety and acclaim as Jonsbo. This Chinese brand, once non-descript and relatively unknown, promises efficient and cool server enclosures, eventually getting their products front and center in the most prestigious communities for those building their very own server from scratch. At the start of 2024, we saw the release of the Jonsbo N4, a new desktop NAS chassis that seemingly wants to coexist between the profiles of the rest of the devices in their portfolio. Arriving slightly less scalable than that of the N3, yet offering more physical space than that of the N2, the Jonsbo N4 is, however, the first NAS enclosure by the brand to support M-ATX motherboards—an exceptionally long-requested feature! So, is this new Jonsbo enclosure a better purchase for you and your aspiring DIY NAS build? Does it deserve your data?

Jonsbo N4 NAS Case Hardware Review – Quick Conclusion

I like the Jonsbo N4 NAS Case, but there is no denying that for so many reasons the N3 is a superior NAS enclosure. Earlier this year when the N4 was first announced, we made a comparison guide on the N2, N3 and N4 (HERE) and reached the conclusion that the N4 was arguably the most niche unit of the series so far, making us wonder if perhaps Jonsbo had got these numbers in the wrong order! Fast forward to now and when we have spent some time with the N4 case and that opinion has not changed at all! The N4 IS a good NAS case, but in efforts to support MATX motherboard use, strange choices have been made in what to do with the increased dimensions afforded to the system. The arrangement of the SATA storage bays is weirdly inconsistent, the decision to go for 6x 3.5″ and 2x 2.5″ (instead of just going ‘route 1’ and just opt for 8x 8.5″ SATA) is a stance choice in 2024 (as the focus on SSDs rapidly shifts away from 2.5″ to M.2 NVMe, onboard MoBos). The funnelling on cables on the system is very clear, the PCIe card frequency is high and the physical design and aesthetic appeal are better on the N4 than any other Jonsbo NAS case. But the reduced motherboard cavity space and it’s impact on optional rear fans, smaller CPU coolers and half-height PCIe cards is going to be a hurdle for more enterprising users! For under $100 (without delivery!), Jonsbo is still going to be the ‘go-to’ NAS case manufacturer in 2024 onwards, but the Jonsbo N4 is still a little more niche a proposal in terms of its physical appeal to a lot of users. A good DiY NAS Case, but make sure that you look into the N2 and N3 case first, as you might find more to love there!

Jonsbo N4 NAS Case Hardware Review – Packaging and Shipping Presentation

Arriving in a Jonsbo-branded case, much like other solutions by the brand, the N4 is currently only available on AliExpress. With a sub $100 price tag, it’s the delivery costs of around $40 to $50 that might surprise you. Eventually, this case will no doubt become more widely available across traditional e-commerce outlets, but at launch, this system seems to arrive at a comparative price point to the rest of the Jonsbo NAS enclosure family.

The page pretty much gives you all the information you’re going to need for an exclusively e-shop purchase. And, for something that most would largely assume would arrive in plain brown box packaging, the N4 retail package is actually surprisingly nice and provides a decent amount of detail.

The contents of the Jonsbo N4 retail package are pretty standard. The enclosure is encased in hard black foam, and the accessories are all included in a branded white accessory box. The unit I ordered online was unscathed, despite the shipping container having a few dents.

Emptying out the retail container and shipping box provides us with pretty much everything I expected. There is the unit itself, but also a fold-out A4 installation guide. There are numerous screws and cable ties for use during the installation.  And finally, there is the assortment of drive handles and rubber grommets. I will discuss these more later on, but that is pretty much everything you get with this system.

The system is not officially available for purchase pre-populated with a power supply, nor does it arrive with any SATA or Molex power cabling included and pre-attached. This is quite a bare-bones NAS enclosure, and alongside the obvious purchase of a motherboard, CPU, memory, and PSU, etc., don’t forget that you’re almost certainly going to need those SATA fan-out cables and possibly Molex power adapters.

Overall, I’m happy with what I’m getting here, and as long as you know that you’re getting a bare-bones NAS enclosure, there’s nothing to be unsatisfied with here. Let’s discuss the external design of the N4.

Jonsbo N4 NAS Case Hardware Review – Design

The Jonsbo N4 case is approximately the same height as the N2 but distinguishes itself by being the widest NAS enclosure from the brand, largely due to the support for the larger M-ATX motherboard cavity internally. Interestingly, this system manages to be nearly identical to most other eight-bay 3.5-inch SATA NAS cases, while technically being a six-bay case traditionally.

There is ample passive ventilation throughout the entire NAS enclosure. Each side of the casing features a ventilation strip positioned beside the motherboard once installed, and the top panel also has a large ventilated area in the metal top cavity to assist warm air in naturally rising out of the case.

The design also introduces a real wood front panel purely for aesthetic reasons, not unlike the AUDHEID 8-bay case. It is surprisingly high quality, even if it largely offers minimal technical or operational improvement to the enclosure. The N4 is available in both black and white metal enclosure options, and although I have the black version here, I would argue the white version looks quite unique with the wooden panel motif. The wooden panel, situated directly in front of the motherboard internally, should not present any heat concerns due to significant passive ventilation around it and ample pathways for the internal CPU cooler to circulate air throughout the system behind this panel.

The storage area of the N4 is located behind a magnetically attached and ventilated front panel at the base of the system. This panel, easily removable via two finger hooks on either side of the enclosure, reveals the individual SATA storage bays of the N4. This vented and mesh dust-protected front panel is of reasonable quality and addresses the inconvenient access to storage bays seen in previous models from the brand.

Overall, I’m quite pleased with the small aesthetic improvements made in the Jonsbo NAS system over the units that preceded it. Drive bay access has been simplified, the stylistic integration of wood and metal paneling looks appealing, passive ventilation is well-designed and plentiful, and overall, the case feels high quality and not at all cheaply constructed. Let’s discuss the storage potential of the Jonsbo N4, as this has been a topic of heated debate ever since the brand announced this new enclosure.

Jonsbo N4 NAS Case Hardware Review – Storage

Discussing the storage capabilities of the Jonsbo N4 has, in the month since its launch, drawn a lot of debate. The system arrives with two tiers of storage: 3.5-inch SATA media and 2.5-inch SATA media. Unlike previous releases by the brand in this enclosure series, all storage media bays are directly accessible via the front of the casing. The first-generation system was a two-drive system, the N2 was a five 3.5” drive system, and the N3 was an eight-drive system. The N4, however, scales things back and arrives with six 3.5-inch SATA storage media bays.

Alongside these, we find two 2.5-inch SATA drive media bays. With the total storage separated in a grid of 4 + 4, this is a peculiar choice, as the use of 2.5-inch SATA SSDs has notably decreased in recent years. There’s a clear division in most storage circles: 3.5-inch SATA storage is used for low-priced, high-capacity storage, and M.2 NVMe SSD storage is chosen for high performance but low capacity. Given that the majority of modern motherboards these days come with at least one M.2 NVMe slot, traditionally used for an operating system SSD, the necessity of 2.5-inch SATA SSD bays in a 2024 NAS enclosure is up for debate!

The debate regarding the storage bays of the system is further exacerbated when you learn that only four of these bays support hot-swapping. Slots one, two, three, and four are all attached with a SATA/SAS backplane located at the rear of the enclosure.

Whereas, the other two 3.5-inch SATA and two 2.5-inch SATA are just empty physical cavities that will require the user to directly connect SATA cables from the motherboard, as well as introduce individual SATA power for each drive. The convenience of hot swapping without getting too up close and personal with the system components on the fly is a peculiar choice of storage deployment in a system released hot on the heels of the Jonsbo N2 and N3.

With the scale of the system’s physical width increased for its support of M-ITX motherboards, the N4 is similarly sized to the majority of other eight-bay NAS systems in the market. Yet, practically all other eight-bay NAS enclosures opt for traditional SATA trays that directly load onto a single 8-port internal backplane. It is an odd choice by the brand to opt for this style of drive insertion.

This is further exacerbated by Jonsbo’s continued decision to forgo the use of traditional storage media trays and instead opt for rubber handles and individual grommet drive screws for each physical drive. Not only does this mean that the installation of 2.5-inch SATA media in these larger bays requires an additional physical adapter, but the installation of the Jonsbo storage media drives with these handles has always felt clunky and poorly served when drives are being moved in and out of the system.

In Jonsbo’s defense, this approach is somewhat of a house style for the brand in many of their previous releases, and they do reduce operational vibration and noise compared to the insertion of metal trays. However, this decrease in drive vibration is somewhat minimal and arguably even less useful when using larger capacity or enterprise drives that are simply too mechanical and jam-packed with hardware to be suitably muted in operation anyway.

All in all, I find these rubber handles for drives reminiscent of something from the early 2000s of entry-level home server devices and feel completely out of place with the rest of the system’s arguably modern aesthetic.

Jonsbo N4 NAS Case Hardware Review – Internal

The Jonsbo N4 features three removable panels for accessing the bulk of the internal system framework. Additionally, several internal cavities/pathways guide cables between the installed motherboard and individual components. Given the relatively compact framework of the system, efficient cable management is paramount to prevent blocking active airflow. Although a bit of a tight fit, Jonsbo mostly pulls it off, albeit with a few questionable choices along the way.

The single 120mm fan is secured with four screws at each corner, and once removed, it allows for easy maintenance of the active cooling fan.

I find myself missing the dual-fan arrangement featured on the N3 model, especially since, short of a substantial CPU cooler, this is the only fan that can be installed in the system. There are no additional placement holes for optional fans.

The system has a PSU cavity that supports an SFX power supply, up to 125mm in height. An empty space above the PSU area is used for funneling cables from the front panel slots five through eight.

The rear fan area reveals four individual SATA connectors that require funneling additional SATA cables from, via either a fan-out cable or individually, into your chosen motherboard. The backplane is powered by a single Molex female input.

The front-mounted USB Type-A and USB Type-C ports connect to three individual F-panel connector cables that run directly behind the wooden section of the enclosure. The system lacks audio sockets and does not feature LEDs for the individual storage bays, presenting an understated case overall.

Removing the top panel is straightforward, done by unscrewing some screws at the rear of the enclosure. This reveals the space available for installing your ITX or MATX motherboard.

Screw points for mounting your motherboard are clearly identified with the letters M, I, or M/I – the latter indicating a shared screw point for either motherboard installation. The guidance holes for PSU power and SATA cabling are clear; however, it’s highly recommended to route these cables in advance of installing your motherboard as doing so afterward will be challenging.

This brings us to another area of the system that’s somewhat divisive. The height of the motherboard installation cavity is quite low, supporting only low-profile CPU coolers. While there are many impressive half-height CPU coolers available, and modern SOC processors often come with slim 1 to 2cm fan-assisted heatsinks, this limitation is notable.

Users often choose NAS cases that support MATX motherboards for the purpose of using more powerful CPUs, alongside the benefits of larger PCIe slots and more DIMM slots. This all necessitates more cooling, making the N4’s limited capacity for CPU coolers a bit puzzling.

Regarding MATX benefits, the system has slots for up to four individual PCIe cards. Realistically, most users will install one to two double-width cards. The system’s lower motherboard cavity height also means it only supports half-height PCIe cards, which should be fine for network interface cards or compact M.2 NVMe upgrade cards. However, modern graphics cards and larger PCIe upgrade cards will not fit.

Realistically, the majority of users interested in the Jonsbo N4 are likely looking for a system suited to multimedia, low to mid-level VM and container deployment, or simply to enhance their home lab. A smaller segment seeking to expand into AI, high graphical demands, or aggressive VM deployment might find the reduced PCIe card capacity limiting.
