A Closer Look - Outside

The MasterBox 600 is designed with function foremost in mind. As such the overall looks aren't super unique, and it utilizes the usual set of materials. That said, Cooler Master has ensured that even with the mesh front, the chassis feels sturdy, making sure that the initial impression is a positive one when it comes to the quality of the case.


In the front, the MasterBox 600 has infused a bit of color with the two lighter gray mesh strips. On top of that the center mesh panel is embossed to give the case some additional depth. It is designed with a really fine mesh and feels so sturdy that it doesn't need plastic support behind it. This results in a very clean view of the include fans. Even the brand logo lines up perfectly with the hub of the lowest fan. You may pull off the cover to reveal the three pre-installed retail-grade SickleFlow140 ARGB units. In the rear, the case looks quite traditional in every sense of the matter and falls right in line with what to expect to see from a $100 chassis.


The main side panel is made of glass and its implementation is nice and clean with a single thumb screw holding it in place in the rear. Turning the MasterBox 600 over, the other panel is all steel and also pinned down by a pair of thumb screws. Cooler Master has opted for silver variants, which is fine, but one could argue that black screws should have been in the budget for the bill of materials of the case.


The PSU bay in the back is nothing out of the ordinary, but does come with two sets of mounting holes, so that you may have the unit's fan facing up or down when you assemble your system. Above that are the seven expansion slots. Unfortunately, Cooler Master has opted for breakout covers and has not even included any as part of the accessories. For a $100 chassis, there is really no reason anymore to cut this corner these days. At the very top, you will find another fan, this time of 120 mm size, set to blow air out the back of the enclosure. Thanks to the elongated mounting holes, you have a bit of flexibility in its vertical placement.


On the top, the mainstream vibes continue with a magnetic, metal mesh cover which keeps dust and grime away from the fan/AIO mounting holes. Here you may comfortably install a radiator of up to 360 mm. The mounting holes are offset, to limit the possibility of cooling in this area colliding with tall components on your motherboard. On the top of the case is also where you will find the IO in form of a power button, a reset/LED toggle, an audio combo jack and the usual set of singular USB-C and two USB-A ports. Cooler Master has deliberately omitted the labels as the reset button is actually used to cycle through the LED options of the included controller.


On the underside, you will once again see exactly what you would expect from a mainstream chassis. There is a dust filter to protect the PSU from dirt. Unfortunately, it is not easily removable without tipping over the whole system. While the case feels sturdy overall, a few aspects seem to go too far into the budget end of things, as having a pull-out dust filter is the norm these days for cases of this price segment.
