The Gungnir gaming case series has a new top model, the 300R Airflow. This 60-litre midi-tower brings, among other things, features that facilitate the installation of components. All in all, we can probably talk about a user experience on a higher level. Whether it lives up to the selling price is up for consideration. The price is set quite high and the innovations that the MSI case brings may not be enough for everyone.
Conclusion
The system cooling of the Gungnir 300R is weaker considering its price. For example, the CPU temperature is at the tail of the chart. The results for the graphics card stick somewhere in the middle. With the fan placed on the grommet cover, the graphics card temperature drops a little, and this is also the case for the chipset and the M.2 SSD.
One of the plus points of the factory design is definitely the graphics card holder, which is visually appealing in addition to its functionality. The glass with the engraved dragon is synchronously backlit with the fans. The harmonisation is taken care of by a controller located under the ceiling. There is space in the case for installing two 360 mm liquid cooler radiators at the same time. Both in front and on the ceiling. An 80/120 mm fan can additionally be placed on the metal grommet cover. It is also possible to place two additional 120 mm fans on the ceiling of the tunnel, or two 2.5″ storage units using brackets. It’s great that they haven’t forgotten about this often neglected space. A big plus is the fast USB Type-C connector, whose theoretical maximum speed is up to 20 Gbps.
The main shortcoming of the case is definitely the absence of a fine dust filter behind the front panel. Also, MSI could improve the design of the top magnetic filter, which in its current form is similar to filters on the cheapest cases. It doesn’t look too much like you have a 180+ euro case on your desk or on the floor. The last, but all the more minor shortcoming, is the metal cover of the vertical cable grommet. With the stiffer cables we use in testing, the cover in its original position collides with the motherboard’s power cable. Fortunately, the cover can be moved one position further and the cable then has plenty of room to bend.
Hardware installation was trouble-free, with the only exception being the metal cover for the vertical grommet. There is plenty of room under the ceiling with large holes for convenient cable connections, especially for the CPU power supply. Cable management from behind the tray is also well thought out. You don’t have to experiment with which cable to shove through where first, and even then you can still close the case comfortably.
Considering the higher price, the Gungnir 300R has more things that could probably use a little more tweaking. These include the weaker system cooling efficiency. On the other hand, there is a neat graphics card holder and several additional positions for 60/80 and 120 mm fans to support the cooling or take it to the next level. Regardless of the price, it is an overall decent case that earns the editorial award “Approved”.

Anytime I see new case (especially costing that much), I immediately compare it to Fractal’s Define 7/Meshify 2 which I find special ones. Maybe not first ones not having any serious flaws, but first ones not having them when also having just anything enineered that well to the point of competition (or just me trying hard to complain) not having ideas how to do it better or improve it further. They are like pc case benchmark and it’s sad to see that they are already three years old, but for all this time nobody managed to create something that good when it could be that easy as copying all of the tricks. The problem of this MSI case is not even trying when costing the same money.
