All about Enermax Marbleshell MS31

Marbleshell MS31 is a mid-tower cabinet, which is available in both black and white. The cabinet has been designed to optimize airflow, with its marble design and mesh front. It is possible to mount a motherboard up to E-ATX size. Next to that, the case supports up to 420mm AIO with a thickness of 38mm, as well as a total of eleven fans. With a mounted radiator, there is still room for a graphics card of 370mm and without a radiator in the front, you can stretch it to 410mm.

The front is a mesh front, with a slightly different design. At the top we have a small logo which reveals that the cabinet is from Enermax. It doesn't give as much of a stylish look, but you still get a cabinet that has a design you don't find many other places.

Behind the mesh front, we have fitted a dust filter. The dust filter can be easily removed to allow the installation of other fans or a radiator.

If we look at the top of the cabinet, the Marbleshell MS31 has inputs for headsets, two USB 3.0 inputs, USB-C, the power button and reset button.

We go further into the cabinet and remove the glass side. The case supports up to E-ATX. There is plenty of space for the hardware, where it is also possible to draw cables both from the top, bottom and side. It is possible to mount a 420mm radiator in the front or 360mm in the top.

Four 120mm ARGB PWM fans are included.

On the back we have seven PCIe expansion slots, which gives plenty of space to mount either more graphics cards or other things that need a PCIe input.

Let's take a look at the back, at the Marbleshell MS31. Do we have 25mm space for cables. There are very open areas that require extra planning when running the cables to be hidden. There are two slots for SSD at the back, as well as a hard drive cage with space for two 3.5". The power supply is also inserted from the side.

Installation of hardware

Before we move on to mounting the hardware in the case, let's take a look at the included accessories. We have everything from screws, pads for hard drives, strips, GPU golder and a manual.

As previously mentioned, the power supply is inserted from the back. It is screwed directly to the cabinet from the outside.

The motherboard that has been fitted is an ATX, together with the RTX 2080 Ti. We still have plenty of space for the front, even if no radiator is fitted. With a larger motherboard, however, we could have had some problems with the cable routing, which would require a little extra finesse.

For some, the need for a specific cabinet may be minimal, and where it is more about a box to be able to assemble the hardware. Next to that, the price can also have a meaning, where you don't want to throw several thousand for a cabinet.

Marbleshell MS31, gave me a bit of mixed feelings. Because even if the quality seemed okay, it had better not be more than that. I kind of got the feeling of standing with a cabinet from the 00s. Where perhaps not much has been made of the interior details.

The rubber on the side for the cables feels "cheap" and easily falls off as soon as you run a larger cable through. The same applies to the metal. Which is a bit difficult to describe, but reminds of the metal you especially find on older cabinets.

It can also be difficult to make a cabinet at a cheap price, and not make some compromises. But despite the cheap price, Enermax has still managed to create a cabinet where you get a lot for your money.

Having said that, it is a cabinet that meets most people's requirements, and especially with the hardware coming out today, where heat is probably the biggest problem. So the cabinet is made with good airflow in mind.

It's also not often that you see a case of that size which, among other things, has the option of 420mm AIO water cooling, this is usually reserved for somewhat larger cases.

We still have USB-C connection on IO, on the front. Also, the cable routing is there, although it requires a little extra work, due to the large open areas.

Despite the cheap price, and the quality is also just on the edge, it is still a cabinet that comes with a lot of features, and that is why I also end the test by giving 8 out of 10. It is especially the quality of the material , which may lag in some areas. But it is still a cabinet that offers a nice design, good space and good airflow. All for a cheap price.


  • Good space
  • Nice design
  • Airflow optimized
  • Possibility of water cooling
  • USB-C on the front panel
  • Hard disk cages
  • Good option for cable routing
  • Includes four fans
  • Price


  • Seems a bit cheap in quality

Score: 8
