Review: Jonsbo D40


Inside the D40

The inside of the D40:

To get inside the case, it’s a bit of a hassle since we first have to remove the top part of the D40. Once removed, we have access to the cruciform screws maintaining the side panels. There, it will be necessary to remove them with a screwdriver then to remove the side panes by pulling them upwards. In short, not simple, we would have preferred a closing system based on hand screws as it is usually the case.

The chassis:

Internally, we find a very original organization since the power supply is located at the front of the case. Seen from the front, we only find, really, the motherboard slot and a long plate on its right. As far as the motherboard is concerned, the case only supports ATX and micro-ATX models

Of course, we find a number of cable passages around the motherboard tray. Two of them are present at the top, while we find two more at the bottom. On the right, we have a small opening and a second, longer one just below. Normally, this should be fine, we should be able to pass our cables without too much difficulty

Be careful though, the cabling part doesn’t look obvious since there will be very little room at the back of the motherboard tray: 2 cm at most, 6 mm otherwise, it’s borderline

Storage slots:

Regarding the storage, the various slots are spread all over the inside of the case. Already, we have a long board with two 2.5″ slots located on the right side of the motherboard. At the bottom, a 2.5″/3.5″ slot is also included. Finally, we end at the back of the motherboard tray with a last 3.5″ slot. This makes a total of 3x 2.5″ + 1x 3.5″ or 4x 2.5″.

The power supply slot:

The power supply, as we told you, will install at the front of the case and vertically. There is no need for a rubber mount or foam surround to dampen vibrations. The power supply is suspended, so it does not rest on… nothing.

As far as the PSU is concerned, you can opt for an ATX model without any real constraints in terms of size. Note, however, that if your PSU is more than 17 cm deep, this will restrict the size of the graphics card, which cannot exceed 305 mm in length. With a compact power supply, the graphics card will be able to measure up to 355 mm in length.

Cooling options:

The case comes with no pre-installed fan. So you will have to go through the case a second time if you want to bring a minimum of airflow to this model.

On the other hand, the five fan slots are noteworthy. A 120 mm is available at the back against two 120/140 mm in the top. At the bottom of the D40, we find three slots in 120 mm against two in 140 mm.

Of course, as far as watercooling is concerned, you wont be able to go overboard. This reference signed Jonsbo will only be compatible with 240/280 mm radiators at the top against 120 mm at the back. At the bottom, it will be possible to opt for 360 mm by making some sacrifices (3.5″/2.5″ storage).

Otherwise, we can indulge ourselves with an aircooling cpu cooler since the datasheet mentions compatibility with models of 168 mm in height!

As for the accessories part, what do we find?

  • An assembly manual
  • The screws and bolts contained in a plastic bag
  • A fan filter to be installed at the back of the box
  • Velcro
  • Nylon collars for the cables

The accessories part is quite original with its additional filter to be placed at the back of the case. Apart from that, nothing extraordinary either

In summary:

Jonsbo D40

With its case, Jonsbo plays the card of originality with a chassis whose power supply is installed vertically, at the front. There will not be really big constraints for the components, unless you opt for a very big power supply. However, I’m a little disappointed about the lack of basic ventilation and the lack of space at the back for cabling. The assembly is going to be tough!
