Not suitable for modern Motherboards, Coolers or GPUs
The N400 offers a decent number of drive bays and airflow options, but several design choices made the building experience more frustrating than it needed to be. * The PCIe slot covers are flimsy and do not provide much support for add-in cards, resulting in poor alignment with the motherboard slots. * Only two of the 3.5” drive bays include tool-free mounts, while the rest require screws. * The 2.5” SSD mounting system is also of low quality and difficult to manage, making cable routing more challenging than it should be. * There is very little space above the motherboard, which makes it difficult to connect cables, especially when using a tower cooler. While the case technically supports two fans in this area, there is realistically no room for them if a larger air cooler is installed. The same goes for the two fans which can be installed behind the drive bay, as they share the same space as the 2.5" mounting adapter. * The case is not designed with right-angle motherboard connectors in mind, meaning compatibility may vary when using SATA, USB, 24-pin power connectors etc. * The included fans are functional but do not compare well with modern, quieter alternatives. * The dust filters are not easy to remove for cleaning. * The case does not come with common motherboard standoffs pre-installed (e.g those shared by both ATX and mATX), which adds an unnecessary step to the building process. * There is no AIO support here. You might get one mounted on the rear 120mm fan, but that isn't going to be enough for modern hardware. If a budget case with storage capacity is the main priority, it can be made to work, especially as you'll be saving a lot of money vs alternative high-drive capacity cases.

Amazing value for a very attractive computer case! I got this for $40 on sale, and it was worth every penny. The metal case is light and mostly strong. Some points are a bit delicate, like the front panel fans and gpu shield thing. The magnetic front panel is great for quick cleaning. My PC takes up less space while looking attractive and keeping my internals cooler than before. I appreciate the cover in the bottom of the case to hide the extra cables from my non modular power supply. Everything but the 3.5 drive bay from my mid tower case fit great into this case.

A great case for those who want a simple yes classy design. Enough room for several additional fans if desired, and was mostly easy to work with. Some areas are a bit tricky to deal with compared to some cases that make life simpler, but everything is made solid and most of the case is metal, so there isn't really any cheap plastic involved. This makes for a sturdy case with decent room for whatever you might need in any good-tier computer builds

An excellent case for simple construction, if the price stays below $50, it is a good option. It is small and has good building materials. Easy to use and has everything you need for a small, powerful PC. Ease of removal, functionality, looks modern, excellent cable management.

Como es de esperarse de cooler master, el case cumple con lo que se requería: nada de luces rgb, aunque bien podría haber venido con 3 ventiladores en lugar de solamente 2. Lo compensé comprando un kit extra. En estos días de PCs con SSD, cuesta encontrar un case con más de.3 bahías para unidades de 3.5". Este case cumple la expectativa: puede alojar hasta 8 discos si se usa la bahía pensada para la unidad floppy (si, es un diseño viejo) o bien se puede usar ese espacio para un bracket para montar puertos USB 3.1 y el Tipo C que viene disponible en la tarjeta madre que se montó en este case. La lámina es delgada pero resistente y no es muy pesado, algo que se agradece. Viene con un diseño para montar ventiladores laterales o una solución de water cooling, sin embargo, y de nuevo, al ser un diseño viejo, carece de opciones decuadas para ruteo de cables, que se complica al ser un full tower pero esbelto, lo que limita un tanto el espacio para el cableado. El diseño del chasis tiene un inconveniente con las nuevas tarjetas que traen algunos puertos colocados en forma horizontal y con la entrada de conexión hacia el frente del case. En micaso pasó que los puertos USB 3 y los pueros SATA 1 y 2 estan dispuestos de esa forma y para poder conectar, hubo necesidad de deformar la lámina pues el diseño pensado para el water cooling, tiene un relieve que impide las conexiones. Hacer un buen ruteo de cables, deja inutilizado el espacio pensado para el watercooling/ventiladores extra. A pesar de esos detalles, el case cumple con el requisito principal: Alojar discos mecánicos de 3.5" para un RAID. Está en pruebas, a ver que tal funciona la solución de ventilación instalada ( ventiladores dr alta ganancia) para mantener el equipo fresco.

I bought this case for my home server. I was looking all over the internet for sub $80 cases with more than 6 drive bays. This is the one I pulled the trigger on. I could not be more happy. There is more than enough drive bays for my needs, the quality of the case is amazing, the value is fantastic, it is super easy to build in, and it comes with all the screws needed for a complete build. The drive bays were the main reason behind buying this case. There are other cases from other brands that feature similar amounts of drive bays, but at almost double the cost. The case quality is amazing, it felt really sturdy with all my hardware inside of it, there was not metal bending or anything. At roughly $75 (when I bought it) it gives a great value compared to other cases. It was super easy to build my server in this case as well, it only took me about 30 minutes for everything. Thankfully this case came with all the proper installation hardware for components, I have had to deal with some cases before that actually did not have all the necessary screws included.
