Jonsbo MOD1 review and test

Jonsbo MOD1 review and test

The previous Jonsbo housings lived understatement. Noble, but yes, not conspicuous should they be. The new Jonsbo MOD1 is radically breaking with this tradition. With bold lines and eye-catching color accents, it really bounces into the eye. However, the premium housing is also to be functional and to convince even water cooling users.

The two current models UMX4 and RM3 represent the typical Jonsbo design. Made of aluminum and genuine glass, the manufacturer creates clear and pleasing lines. Also in color both models are quite classic, because they can be ordered in black or silver. With the novice Jonsbo MOD1, however, little of this reserved elegance is left ….

In this model, Jonsbo breaks the simple form-language and relies on design that is already reminiscent of modern art. In addition there are striking color pigments, optionally in red or as in our test sample in intensive green. Even if Jonsbo breaks with its previous design conventions, the manufacturer remains faithful to the material at first sight. The Jonsbo MOD1 is also externally in brushed aluminum and with a lot of real glass. At the core, however, there is also an innovation here. While the Jonsbo models mentioned above are made of solid steel, the Jonsbo MOD1 is a full aluminum case.

However, the new design is not just a fashion, but also signals a functional reorientation. The Jonsbo MOD1 was developed explicitly as a water cooling housing. The basis for the development were not only the ideas of the manufacturer, but extensive customer surveys. The result is a housing that can hold a 360 mm radiator in the lid as well as in the floor and on the drive shaft. The interior is spacious enough for a high-end system that can be presented well in the eye-catching Jonsbo MOD1 by the tempered glass.

Design and choice of materials also have their price: around 270 euros must be taken into account for the purchase of a Jonsbo MOD1. The Mini-ITX housing Jonsbo MOD1 -Mini, which is also available, is also less expensive and can be installed in a 240 mm radiator. This mini-model costs around 180 euros.

The accessories are limited to the essentials. In addition to the tight, four-sided instructions and the mounting material, the Jonsbo MOD1 only has ten black cable ties and a system speaker.

Exterior appearance

Although Jonsbo has both sides and the cover made of 5 mm thick real glass, the front consists of two layers, thick-walled aluminum layers. The front level has been slanted – this gives an outlook on a central design element. External drives must be dispensed with as is the case with so many current housings.

The green and high-quality Powertaster was integrated directly into the front just like the I / O panel. The two USB 3.0 ports are not shown in blue, but also in green. Two USB 2.0 ports and the standard 3.5 mm audio jacks can also be used.

The thick-walled glass panels are installed at a distance from the aluminum. First, for each disc, four spacers are screwed into the housing, which are milled from the solid. The washers are guided over the screw thread of the spacers. Rubber bands on the spacer and on the washers protect the glass from damage and prevent vibrations from being transmitted easily. The rubber rings on the windows are not fixed. When the washers are placed on the spacers, they therefore jump out quickly and have to be pressed between the washer and the screw thread. On the other hand, the last step is easy – the washers are secured with knurled nuts. Visually and haptically, the assembled housing with the protruding glass surfaces looks very valuable and noble. However, this structure means that there is no dust-proof interior.

Even the front was marked by the oblique course. The design element is also repeated in the shape of the left glass surface. Jonsbo has darkened all glass surfaces comparatively dark (much darker, for example, as Lian Li for the PC-O10). Depending on the light conditions and angle of view, therefore, the glass can be seen partly as a part of the surroundings rather than the interior.

For Jonsbo, it was important that the Jonsbo MOD1 meet the needs of users who want to install a self-built water cooling system. As a consequence, the manufacturer has reserved in the enclosure the areas above and below the mainboard for radiators. The power supply travels into the drive bay and is powered by an extension cable. For a 120mm single-radiator or simply a 120mm fan, the rear panel provides an appropriate mounting location. However, a fan grille is missing.

Glassless, the design of the Jonsbo MOD1 is even more recognizable. The basic construction consists of an aluminum element, which forms the mainboardtray and then winds around the drive shaft and around the connection box in the front area. There closes almost seamlessly (at the Videodreh we have overlooked the transition) a shorter aluminum element, which bulges the front connection box. The basic construction is supplemented by further aluminum surfaces such as the back wall and the two fan covers in the lid and in the floor. Both the floor and the lid can accommodate three 120 mm fans or a 360 mm radiator.

The bottom floor vent looks quite similar to the one in the cover, but there is at least once a dust filter. The simple plastic lattice was screwed, the cleaning is accordingly more difficult. In general, dust protection in the Jonsbo MOD1 is however only very limited possible – which also makes the open design of the fan screen clear. Jonsbo presents the MOD1 on robust, silver-colored HiFi feet and also thinks of gentle rubber bands.

Internal structure

If you look into the mainboard chamber, the Jonsbo MOD1 shows the drives and the power supply elegantly. They finally find themselves in their own manhole. Around the motherboard remains around properly. This makes 7.5 cm for the upper 360 mm radiator available between the main board and cover. Below we measure about 6 cm between the ground and the bottom expansion card slot. In the end, it depends on the mainboard format and the expansion cards used, as the height of radiators and fans may fail.

For the installation of the maximum of seven expansion cards knurled screws are used. They are also necessary, because with a normal screwdriver the screws are not reachable. Correspondingly, the user should ensure that the knurled screws are not tightened too tightly.

The side wall of the drive bay is embossed by several green screws. They hold the large Jonsbo logo and the five drive carriers. Three additional 120 mm fans can be installed on the inside wall of the shaft if required. Another 360 mm radiator space can be used here. Because of the limited airflow and the effects on the maximum graphics card length, however, the radiators in the floor and in the lid should be preferable.

Of the five drive racks, the four upper racks can be used twice. Among them is a 2.5-inch drive installed, decoupled on them a 3.5-inch hard drive. In order to mount the drive, the carriers must almost always be removed – only the top SSD can be installed directly in the Jonsbo MOD1. The bottom drive carrier differs slightly from the other carriers – it only accommodates an up-facing 2.5-inch drive.

In the upper part of the bay, the ATX power supply is installed vertically and powered by the internal power cable. The maximum power cord length is 20 cm when all drive carriers are installed. It can be increased even further by the removal of drive carriers.

On the Mainboardtray there are sufficient cable management procedures available. Jonsbo does not use jackets or covers. This also shows the cables in the mainboard segment, which run behind the feedthroughs. Long slots next to the mainboard facilitate the mounting of a tube expansion tank. Jonsbo, on the other hand, did not use a special mounting solution for the pump.

The power I / O cables are what the power supply installation in practice limits more than the mains cable length. They are so unfavorable that they block the way to the power supply and have to be bent aside with force.

The hardware installation is largely uncomplicated in the spacious housing. Only the drive assembly and the handling of the three glass surfaces are somewhat more complex than in the average case. Because Jonsbo delivers the fanless fan housing, we have at least equipped a back-ventilator for the semi-passive test system. A be quiet! SilentWings 3 120mm PWM, which we can operate at full speed of 1,450 rpm.

Jonsbo draws the color scheme consistently with the logo lighting and lets the company’s lettering light up – at least as long as the corresponding S-ATA power connection is also connected to the power supply. The view into the mainboard chamber also makes clear once again that despite the many glass surfaces not much of the installed hardware is to be seen. If you want to see more of its expensive components, you need to look for additional interior lighting. However, the advantage of the heavily tinted glass is that you can also see little of the cables behind the tray.

Test system, ventilation and measurements

In addition to the processing and the equipment of the housing, the temperature behavior is of fundamental importance.

Temperature measurements:

In order to determine the maximum temperatures of the processor, the CPU was charged for 30 minutes by means of the free Stresestest tool Prime 95. Since the Small FFT test has the highest heat loss performance, we use this mode and log the maximum core temperatures with the system tool Lavaly’s Everest. The individual core temperatures are added and divided by the number of physical nuclei. At the same time the graphics card is loaded with the Stresstest Furmark.

The consideration of the temperatures in the idle state (= no-load) becomes increasingly uninteresting, since both the processor and the graphics card manufacturers have developed very good current storage techniques. In the course of this, the data cores are clocked down in the idle state and the current voltage is reduced. As a result, the generated waste heat is reduced to a minimum.

Actually, our temperature measurements should determine how powerful the factory cooling system is. For a fanless housing like the Jonsbo MOD1 we have to work with our own fans. The SilentWings 3 installed on the back wall manages to cool down the semi-passive test system to good temperatures. The Jonsbo MOD1 also benefits from the open design, which facilitates air circulation.

Volume measurements:

For our volume measurements, we use a Voltcraft SL-400 sound level meter, which we place 20 cm away from the housing.

At 1,450 rpm, a SilentWings 3 is no longer very quiet. Accordingly, the volume in our test configuration is moderate. In general, it can be assumed that fans (and water cooling pumps) are more audible in the open Jonsbo MOD1 than in a closed or even sound-insulated housing.

Height of process cooler:

Even if the Jonsbo MOD1 was developed especially for the combination with a water cooling, it also takes up tower coolers problem-free.

Graphics card length:

There are also no restrictions on the graphics card selection. Without a front fan there are generous 40 cm available.

Space for cable management:

the right side we measure a distance of about 2.1 cm. This is only an average value and in fact cables must be bundled well in order to be able to mount the right glass side. For aesthetic reasons, one will pay particular attention to cable management at the Jonsbo MOD1.

Material thickness:

Jonsbo specifies a material thickness of 5 mm for the tempered glass and a material thickness of 3 mm for the aluminum. We can confirm this almost as we measure for the aluminum 2.95 mm.

Conclusion

Already the first Jonsbo housings were a surprise. At an attractive price, they were presented with a high-quality aluminum outer shell and typically in timelessly beautiful designs. With the Jonsbo MOD1 is obviously quite different. At a price of 270 euros it is by far the most expensive Jonsbo model. But there is another target group for this – enthusiasts who are looking for powerful water chillers and are looking for a truly extrovert housing.

The entire structure of the Jonsbo MOD1 is based on this target group. Jonsbo clears the 360mm radiator slots and even rearranges the ATX power supply behind the front – wherever the optical drives will find space. As a result, both the top and bottom of the mainboard will have space for regular radiator zones. The interior is also spacious enough to accommodate long graphics cards and typical tower coolers.

At first sight even more striking than the suitability for water cooling is however the new design, which connects aluminum and glass surfaces in a refined way and additionally also with Farbtupfern in green or red striking. The daring look with slanting lines and the large glass surfaces certainly does not meet every taste, but it has a harmonious effect and ensures that the Jonsbo MOD1 is guaranteed to be noticeable. Functionally, however, with a view to sound and dust protection, clear cuts have to be made. There are also some details that are still to be improved. This includes the rubber rings, which are much too easy to detach from the glass panes, but also the cable guide, which blocks the way to the power supply. Although the combined drive units are efficient, drive mounting is comparatively complex.

With the Lian Li PC-O10, we recently tested a housing that is similar to the Jonsbo MOD1 high show value and is also suitable for the installation of a water cooling system. Nevertheless, the Jonsbo and Lian Li models differ massively. The PC-O10 shows itself sober, elegant, almost undercooled, despite the large (and less heavily toned) glass surfaces, as the Jonsbo MOD1 is still powerful and attention-grabbing. Functionally, both models also pursue quite different approaches. Lian Li integrates the glass surfaces into the simple cuboid shape and ensures proper dust protection. Where Jonsbo drives drives and power supply into a bay, Lian Li creates a separate chamber in which the cables are also effectively hidden. Nevertheless, the PC-O10 is significantly more compact, space-saving and lighter (7 instead of 13.5 kg) with 242 x 493 x 376 mm (W x H x D) to 250 x 505 x 638 mm (W x H x D). It also offers only a 240 mm radiator location and limits the selection of components. Overall, the PC-O10 (and certainly also the larger sibling model PC-O9) looks more mature and more everyday, the Jonsbo MOD1 is noticeably more and leaves the user more room.

The price-performance ratio of the two casings we can not currently compare, because the purchase price for the PC-O10 is still not fixed. What is exciting is a look at another case – the In Win S-Frame. The limited model of 2014 cost not only about 800 euros, but could have inspired Jonsbo to develop the Jonsbo MOD1: in Win it had formed from a single, two-meter-long aluminum piece and at least the sides glazed in a similar way as Jonsbo. While the S-Frame remained an exotic lover’s item through price and limitation, the price-performance ratio looks at the 270 Euro expensive Jonsbo MOD1 at least a bit more attractive – especially since the Jonsbo model is more versatile.

Also the Jonsbo MOD1 is anything but a case for everyone. Apart from the price, the open structure and the polarizing design also ensure this. But ultimately the case should be something special – and exactly that is the Jonsbo MOD1 also. The extraordinary, water-cooled creation of aluminum and real glass is therefore also distinguished by our technology award.

Positive aspects Jonsbo MOD1:

  • High quality materials form a striking case with striking color accents
  • Design has also been consistently pursued in detail, e.g. With green colored USB ports
  • Tidy mainboard chamber, three 360 mm radiators
  • Plenty of space for long graphics cards, enough space for tower coolers
  • Each drive has two drives (apart from the lowest carrier), decoupling for 3.5-inch drives
  • Thumbscrews for expansion card mounting, knurled nuts on the glass surfaces
  • Enough space for cable management, well accessible I / O panel

Negative aspects Jonsbo MOD1:

  • Open housing construction, hardly noise / dust protection
  • All fan slots limited to 120 mm fans
  • I can not get it from the power supply, I / O panel cable comes across the power supply
