Well built case for the money!

Reviewed in the United States on June 2, 2018

Style: Micro-ATX MBPattern Name: TowerColor: BlackVerified Purchase

Absolutely love how this case and build came together. Plenty of room for a simple build, and I love the option of moving the power/usb's around rather than them always having to stay in the same place. SSD installs are clean, love that the case doesn't have a big stack of metal in the front for HDD, but keeps the HDD hidden behind the back panel which still leaves plenty of room for extra cord. The power supply gets installed securely with a bracket in the case, and is installed a little further into the case to allow for a nice handle on the bottom backside of the case. Overall this case is WELL WORTH the small amount they are asking for. I have built with cases that cost 3x as much that don't make as much sense as this case did. Beautifully built.

Great design executed awfully.

Style: Q300P RGBPattern Name: TowerColor: Q300PVerified Purchase

***Q300P***
This case sucks, and especially not air. It just sucks. I bought this case for a build, tried to cut a corner by going cheap on a case and should have just spent some extra on a better case. I love the look of it, the handles and RGB look awesome. BUT. That’s about all I like. It’s absolutely massive for a Micro ATX case, it’s wider and taller (with handles) than most ATX towers. The “hole” case design is just awful. It makes for absolutely no air movement, on top of the classic Cooler Master plastic panels that choked the air even more. Also the fans were loud not because they’re bad fans, but because the air was just hitting metal on the front. The front AIO panel had two screws that were so tight from factory they rounded off, and I couldn’t get them out. I have a fully modular PSU and cable management still wasn’t fun. The placement of your SSD is just weird as well. Just all around I hate this case. The only way I’d recommend this case is if you are constantly moving it because that’s the most well thought out and most well built thing was the handles.

The MasterBox is the Master of Budget cases.

Reviewed in the United States on May 1, 2018

Style: Micro-ATX MBPattern Name: TowerColor: BlackVerified Purchase

I had some old parts laying around and my son wanted a gaming computer. So, I went around looking for a case to stuff all this stuff into that was nice looking and quality. He was given the following:

Intel G4600
Asus B250M-K
8GB Corsair Vengeance LPX DDR4 2133
XFX RX560 4GB

We were just using parts that were laying around and acquired from friends, so we don't have anything fancy here or any crazy RGB lighting or color schemes. Just a budget-minded micro-atx build for a budget case.

The design on the dust filters is pretty nice, it's not fooling anyone and you can tell it's just a design on a filter, but it does a good job of looking the part and appearing more exquisite than it is. The dust filters cover the top, front, and the bottom of the case and are simply attached by magnets. It's so easy to pop them off and clean them, literally in seconds. It's a very refreshing change to most cases with poorly designed and hard to access dust filters.

Airflow is amazing. The entire case is open on the exterior and the only thing covering the holes is the dust filters. A front mounted radiator would work great for water-cooling. You could also mount smaller radiators on the bottom or rear. In my particular case, I do not think I could get a 240 radiator to span the top without interfering with the CPU cooler, but a 120 would fit fine if positioned at the front.

The USB ports on the side are a nice touch and can be positioned on any of the 4 sides of the case. The only hiccup with doing that is the wiring must follow the ports wherever they go. So, you have to plan ahead so the wiring doesn't get in your way, for instance the wiring may block the mounting of a large radiator if positioned in the front.

Wiring is easy and there is plenty of room to cram your cables out of view. I'm using a non-modular PSU and I was able to hide all the unused wires just fine. There are also nice spots to mount your drives on the backside of the case.

The window is tinted and a little dark. I do not have any lighting in the case yet, but it's difficult to see inside when there is not good lighting the room. I'll definitely be adding a small light bar to bring it to life. If you have RGB fans and components though you should be fine. The window is not glass and thus it scratches easily. The tinted nature makes it hard to see the scratches at viewing distance though, but that's just the nature of these windows. Unless you're gonna drop money on a glass case it's just something you have to live with.

Another small little touch is you can stand the case up like you normally would, but they also included rubber feet on the back-side of the case. So, you can actually lay the case down flat if you wish and have the window facing up for everyone to view inside the case as they walk by.

Honestly, I'm just really impressed for $40. It's not made of gold or anything, but it's just well designed and good quality for this price range. It's also a nice looking case that would look nice anywhere in the house, even the girlfriend or wife won't get mad if this is in the living room. I definitely plan on using it the next time I build a PC for a customer.

Great Budget Micro ATX Case

Reviewed in the United States on February 15, 2019

Style: Micro-ATX MBPattern Name: TowerColor: Q300L TUFVerified Purchase

I was looking for something smaller and affordable to transplant my microATX system into from an old Antec 900 that provided decent air flow for my 4790k and RX 580 and I settled on the Q300L TUF edition. There is decent room in the back for cable management but I suggest going with a modular power supply to save the space that's there. I have an older Corsair CX750 that isn't modular and I am having a tough time closing the back cover completely and I don't have any room in back for my RGB controlller and all of the wiring. This is definitely a great case for the money, though. The modular structure and customization options are hard to beat with other manufacturers.

Avoid this case!

Reviewed in the United States on April 21, 2019

Style: Micro-ATX MBPattern Name: TowerColor: BlackVerified Purchase

The case is cheaply put together. The magnet side cover is a gimmick that becomes a headache. The rubber piece that holds the filter screen easily comes off and get lost. The case gets one star because the basic of any case (both side open for easy install and easy cable management) is at least there. The fan that came with the case came broken and for something so cheap it wasn’t worth going through the hassle of trying to get a replacement fan instead I ended up using one of my older fan. This became such a headache that I ended up replacing it with something else. Maybe in the future I will end up drilling this case out and use it for something else. It’s a complete waste of money.

Misaligned holes = no fan support for top

Reviewed in the United States on April 13, 2019

Style: ATX MBPattern Name: TowerColor: Q500LVerified Purchase

All the holes are misaligned. 120 or 140mm fans will not work in the top. None of the holes line up anywhere.
Also what is the point of bottom fan support if the thing barely sits 2mm off the ground?
Moved my build from a HAF 932 Advanced to this, which was a huge downsize in case, but upsize space saved and portability.

✔ Awesome Little Case! (with a Few Small Flaws)

Reviewed in the United Kingdom on October 3, 2018

Style: Micro-ATX MBPattern Name: TowerColor: BlackVerified Purchase

Having had a larger PC case for a while I thought it was time to move to a smaller option. I liked the look of the BitFenix cases but at around the £50 mark, the CoolerMaster Q300L was just what I was looking for price and design-wise.

Being able to choose where the USB and power buttons are placed is a cool idea but if you want to use it at the top (like in my setup - Pic above) you will need a USB extension to run the cable down the back of the case.

There's plenty of room for cable management and the build quality is good. I have a full sized HDD at the back and there's also space for two SSD's.

Having all the holes means that you don't get much airflow pressure but I haven't had any heat issues with my overclocked AMD 1700X. If you're looking at having your PC on the floor, I woudn't choose this case as it'll most likely be full of dust in a few months. For desktop, I've had it running 4 months with minimal dust although you can see a slight dust ring around the front intake fan.

When setting up be careful with any fluff and this will easily get stuck into magnet dust filter mesh.

If you do decide to buy the CoolerMaster Q300L, you'll also need to invest in some fans as it only comes with one medium-volume fan. LED fans looks great and I've added three plus used the included fan as a front-intake.

Pros
✔ Cool Design
✔ Build Quality + Cable Management
✔ Removable Magnet Dust Filters
✔ Compact Size

Cons
- Only One Fan Included
- Perspex Window Tint Is Very Dark
- USB Cables a little short

I also upgraded the CPU fan to a Arctic Freezer 7 Pro and there's plenty of horizontal room left. If you're going for a big CPU cooler, you might have to watch out with the clearance.

Cheers,
Jim!

Nice looking case, but with a STUPID location of 3.5" HD mount.

Reviewed in the United Kingdom on April 4, 2019

Style: Micro-ATX MBPattern Name: TowerColor: BlackVerified Purchase

Before I get to my main criticism of this case, I will list the positives:
1) Very clever magnetic dust filters which double up as aesthetically attractive (but still understated) covers of the front and top.
2) Beautiful smoked side window, made from polycarbonate (not glass).
3) Clever option of having the case stand vertically or flat, as it has rubber screw feet on the non-windowed side panel.
4) Tons of room behind the motherboard panel for cable management, making for a very tidy build indeed.

Now the negatives (1 big one really):
1) The location of the HD mount is behind the motherboard panel. This is an area that is TOTALLY unventilated, and so the HD gets very hot here. The bracket itself is clever, which is a plate that is screwed to the HD and then this plate clips (and secured by a thumb screw) into its mount.

Because of the excessive heat build-up of the HD (obviously not helped by ZERO air-flow and heat from the back of the CPU), I decided to mount my 3.5" 2TB hybrid drive elsewhere. There's a few alternative locations for 2.5" drives, but not my bigger 3.5" HD. I re-used a mounting bracket from an old build and mounted it on the case's floor panel in front of the PSU. It stays MUCH cooler there.

Overall the result is good. But I cannot fathom the hideous design choice of mounting the 3.5" HD behind the motherboard where it will bake. If you're only using 2.5" SSD/HDs then you will be fine.

Rapporto qualità prezzo indiscutibile!

Reviewed in Italy on December 17, 2018

Style: Micro-ATX MBPattern Name: TowerColor: BlackVerified Purchase

Partiamo dal prezzo: 37€. Di solito a questa cifra si trovano solo case di marche poco conosciute o comunque con soluzioni economiche per quanto riguarda la disposizione dei componenti o del cable management.

Cooler Master invece questa volta si è davvero impegnata e ha tirato fuori una piccola bomba.

La prima cosa che salta agli occhi e la modularità del case con possibilità di installare le ventole o i radiatori dove e come si vuole (nei limiti del formato M-ATX) e perfino l'area pulsanti si puà spostare a piacimento sui 3 lati del pannello laterale, permettendo di trovare la posizione più comoda in base alle esigente (ad esempio io li ho spostati in alto).

Il cable management è facilmente gestibile, merito dello spazio posteriore e dei vari fori per i passaggi dei cavi.

La lamiera è rifinita molto bene, tutti i bordi sono arrotondati e non ho trovato nessuna parte tagliente.

Ovviamente non è fatto per sistemi complessi con tanti HD/SSD o con Kit a liquido Custom. Ma per Rig Gaming (anche di fascia lata) ma senza mille componenti direi che è perfetto per il prezzo a cui viene proposto. Inoltre è davvero contenuto come dimensione e all'esterno sono presenti filtri magnetici antipolvere.

Attualmente monta un i7 6700K con GTX 1070 e mi sono trovato decisamente meglio rispetto al Bitfenix Phenom che ho abbandonato per la disperazione (e che ho pagato più del doppio)

First build went well.

Reviewed in the United Kingdom on October 9, 2019

Style: Micro-ATX MBPattern Name: TowerColor: BlackVerified Purchase

Probably not the best idea ever to do a tight mATX build as my first PC build but overall went well.

Word of advise be careful with the power panel, I didn't realise the panel had 4 screws holding it in the case (thought it was just the 2) and removed the top plate as it came off easily only to find that it would not go back on the same again and the power button was held on by this plate (rewired my case so that the reset button is now the power button, and positioned the power button for show).

Case has managed to somehow swallow 2070 super gaming X trio but this was a very tricky install (this was why the power panel had to be removed).

Cooler master ml120r argb cooler fit well too but getting the pipes in the correct position was also tricky.

I have 2 mf140r as intake at the front and the original 120 fan from the case positioned at the top as exhaust near the RAM. So case is very adaptable and nothing is running too hot.

Lots of room in the back for cables, do not have any HDD/sata SSD (only m.2) installed though so can't comment on cable space when these are taking up space. But do have the RGB controller from the ml120r back there running all the RGB fans. Some cables can be fiddly to run (especially the CPU power cable connecting to a MSI b450m mortar max).

Overall pleased with this case, looks good and functions well.

Para equipos compactos ITX o Micro-ATX

Reviewed in Spain on August 1, 2018

Style: Micro-ATX MBPattern Name: TowerColor: BlackVerified Purchase

Hello Amigos Amazon
Buena caja para montarnos un equipo personalizado, Tiene características muy interesantes y bastantes opciones para el cableado.

El chasis esta pensado para usuarios como yo, Que buscan armarse un equipo personalizado sin depender de esos chasis tan exagerados y de gran tamaño.
También existimos los usuarios con motherboard de formatos (Micro ATX) - (Mini ITX)

Esta Torre destaca por el uso de filtros anti-polvo magnéticos en el panel frontal y en la parte superior.
Al ser magnéticos se quitan de manera rápida y sin complicaciones, Solo tenemos que tirar de ellos para sacarlos.
Este diseño hace que sea fácil limpiarlos.

Trae incorporado un ventilador trasero bastante silencioso con unas RPM De 500 rpm hasta los 1080 rpm.

Soporta hasta un máximo de seis ventiladores, dos delanteros, dos superiores, uno trasero y uno abajo.

Los 2 ventiladores delanteros pueden de 12mm o 14mm y estos serán los encargados de la entrada de aire fresco.
Los 2 ventiladores de la parte superior pueden ser de 12mm y son los que expulsaran el aire caliente.
El la parte trasera viene incorporado un ventilador de 12mm y es el encargado de expulsar el aire caliente.
El la parte de abajo se puede poner un ventilador de 12mm o de 14mm y este ayudara a meter mas aire fresco.

Dentro del chasis hay algunas oberturas escondidas por donde pude pasar los cables y conexiones de los componentes y todo queda de manera limpia y ordenada.
Nunca había tenido un chasis con tantas opciones para los cables (Se agradece)

Este chasis esta muy logrado y gracias a todas sus opciones y configuración puede quedar una Torre bastante limpia, Sin cables por medio, Esto evitara que el flujo de aire se interrumpa por culpa de obstáculos.
Si eres de los que tiene un poco de maña y paciencia te quedara una torre super limpia y bonita.

Si lo acompañas de algunos ventiladores y tiras de Leds tendrás una Torre personalizado estupenda.
Sera tu creación y eso no te lo quita nadie.

Por las noche es cuando mas destaca por el lateral, Aunque me hubiera gustado que este lateral fuera de vidrio templado y no de plástico como este, Aunque por este precio es comprensible.
Si tienes ganas de hacerte un PC personalizado aquí tienes el chasis perfecto.
Te puedes montar un ordenador en condiciones.
Es una torre muy chula e interesante con muchas opciones para el montaje.

Dejare algunas fotos, Pienso que una foto vale mas que mil palabras.
Cualquier duda puedes preguntar y recuerda que un simple clic anima a dedicar mas tiempo a valorar un producto y siempre es confortable ver un agradecimiento.
Goodbye friend ☺ Very good
