Product Description
The Master Box Q500L supports a standard ATX motherboard and PSU in a highly compact layout. With the same exterior dimensions as the Master Box Q300L, support for a standard ATX motherboard was made possible by maximizing the usage of internal space. Although the PSU is mounted by default at the top/front of the chassis, the mounting bracket allows for the repositioning of the PSU depending on preference and form factor. For instance, if a mini ITX or micro ATX motherboard is used instead of an ATX in the Master Box Q500L, the PSU can be mounted in the conventional position of the bottom, rear to allow for increased front panel ventilation and configuration options.

Customers are mixed about the airflow in the computer chassis. Some mention that it has good airflow and dust protection, while others say that it doesn't have good enough ventilation. The case has plenty of ventilation on 4 sides, and the extra fans make a noticeable noise, but it puts out a lot of air, keeping things cool. However, some customers say that the air flow isn't good enough and the dust filters don't allow for good air flow.

"...I do casual gaming and this is my first PC build. The case was pretty easy to work with and cable management was actually no problem..." Read more
Customers are mixed about the cooling of the computer chassis. Some mention that it can be sufficient with a fan everywhere, while others say that it gets as warm as a toaster. They also say that the CPU runs a bit cooler and the VRMs are nice and chilly. However, some customers say that is very small so heat can be an issue, and the case just will not stay reasonably cool.
"...I've had a significant increase in temps and the case is warm to touch when my PC's under stress...." Read more
"...In my old case, it would hit 80c all the time. My CPU runs a bit cooler now too, and my VRMs are nice and chilly barely reaching 60c...." Read more
"...i7 CPU, not overclocked, and during Lightroom exports, the core temps were hitting 100. Moving the dust filter to the top helped a bit...." Read more
"...The system runs cool, quiet and smooth, no thermal throttling. Front and top are basically all open surface covered by magnetic air filters...." Read more
Customers are mixed about the fit of the computer chassis. Some mention that everything fits nice, it fits a full size ATX board, and can go sli with it. However, others say that it doesn't fit very well, it's small for an ATX case, and is far too cramped inside.
"...It will fit a full size ATX MB...." Read more
"...flaw with them is that it doesn't offset the holes at all so you cannot get a snug fit on the screws unless you use some sort of washer to add space...." Read more
"...This fits perfectly with my 4060. The wiring is super easy and simple too...." Read more
"...The power supply is a tight fit at the front of the case and exhausts upward...." Read more

This case is fantastic. I decided to downsize from a Cooler Master Masterbox Pro 5 RGB (as seen in the pictures) and this case is perfect. My temperatures for my GPU (Vega 56) and my CPU (Ryzen 7 1700x OC'd @4.1ghz) are running cooler than ever. My GPU rarely gets about 55c, even during extended gaming sessions. In my old case, it would hit 80c all the time. My CPU runs a bit cooler now too, and my VRMs are nice and chilly barely reaching 60c. That's a far cry from the 95c temps on the VRMs I was getting in my old case. I have ZERO issues that others seem to complain about.
People are calling it the "masteroven". Not even close. What's so hard about adding fans?? The Deep Cool fans I have (3 120mm RGB and 2- 140mm RGB) allow it to run very cool. Air flow is not an issue at all. I have the very bottom 2 fans and the bottom front on pull with the fan on the 120mm rad and the 2- 140mm fans on top exhausting, taking advantage of the nature of heat rising and also getting excellent airflow through my blower style GPU and also across the VRMs of the motherboard. The PSUs fan exhausts up as well, following the path of the airflow.
Building inside this thing was a dream, having built 8 PCs in the past year and a half, I have to say its one of my favorite cases to build in. Plenty of room to fit full size components, and plenty of room on the back of the motherboard tray for cable management with plenty of hold-down points for zip-tying.
It looks awesome and exceeded my expectations. My next step is definitely a custom loop water cooling setup for both the GPU and CPU. I'll update this review when that happens.

The case can be inverted if you pop out the feet from the bottom, which is one of the best things about it. You won't have to worry about missing out on the view panel if your PC needs to sit on the left side of your desk. I don't know if there's a better budget-friendly option with this functionality.
The downside of this case is that it has the nickname "MasterOven" for a reason. The holes along the chassis are too small and spaced out to allow for optimal airflow. I've had a significant increase in temps and the case is warm to touch when my PC's under stress. If you have the right tools, you can cut out holes for your fans, but the design could've been better in the first place.
The front panel is a little flimsy when plugging in a USB cable and it also would've been nice to have the option of glass. My acrylic panel arrived with micro-scratches and I still need to buff them out.
The last two bits mentioned aren't deal-breakers, and if it weren't for the airflow problems I'd give this case 5 stars. I'd recommend getting it if you need something compact and can make the modifications for better airflow.

Recomendaría más la versión micro ATX ya que para eso fue planificado y después hicieron la modificación para tamaño ATX completo.
Tengo un instalado en ese gabinete una T. Madre ASUS ROG STRIX B550-F, cupo a la perfección pero hay que destacar por ejemplo que de tarjeta de video cupo perfectamente mi RTX 2060 ASUS por sus dimenciones que son compactas, si estás planeando una tarjeta de video más grande vas a batallar mucho al momento de armar las cosas por el espacio reducido y el flujo de aire no sería el mismo.
Al momento de conectar cables si fue un poco tedioso porque no hay espacio extra para cables que no se ocupan y tendrías que tener un buen manejo de estos para que no se amontone todo y pueda cerrar bien.
El resultado fue bueno sobre todas las cosas, si en la habitación entra mucho polvo tendrás que tener cuidado con eso, aunque tenga los filtros es muy propenso a que entre mucho polvo en el gabinete entonces hay que hacer limpiesa regular.
En cuanto a tamaño si estoy muy feliz con eso, no quería una torre completa y esto cumple bastante bien, sobretodo para espacios reducidos.

El vendedor aun siendo externo a amazon fue super rápido, aunque el producto me llego 3 días mas tardes de lo esperado por fallo logístico del repartido ( el producto llego en el tiempo estimado que marco el vendedor, el no tuvo la culpa).
which allows for a unique use of all the space. I fit a Gigabyte GA-H97-Gaming 3 ATX LGA1150 motherboard
in with chunky Cooler Master heatsink & fan comfortably. Good quality as always from Cooler Master..
Excellent space & cost efficient case option for building a simple gaming or blender rig.
es perfecto para meter desde una ATX a una Micro ATX. eso si, debes de batallar mucho viendo donde pondras la PSU o fuente de poder, aparte de que el cable que se conecta a esta y a la salida del gabinete es bastante cortito y hay algunos puntos donde no la podras colocar. pero en si, puedes darle la orientacion que quieras al equipo. bastante bueno la verdad y con excelente espacio para la GPU. eso si, si quieres meterle varios HDD solo tiene lugar para 2. para SSD y HDD de 2.5" tiene 3 ranuras. asi que ten en cuenta eso por si eres creador de contenidos y pensabas tener varios discos internos. le cabe un enfriador Cooler Master Hyper 212 Evo sin problemas por si te preocupaba el espacio para el enfriador. tambien hay espacio para IO.
