Cooler Master Q300L V1 Micro-ATX PC Case, High Airflow, Transparent Panel

Super budget case for a super budget build. Happy with the case. It's not the most solid thing in the world but it holds the guts of the PC just fine.

So first I'd like to state that this review is specifically for the Q300L model. Amazon does this annoying thing where they mix all the reviews of all the models together and I can't stand it so I'm just stating the model flat out. I just built my 10 year old nephew’s PC using this case and I have to say that I was very surprised at how much I loved building in this case. Originally I bought the Compucase HEC HX300 case for 30$ from Newegg and I was just frustrated at the lack of air flow from that case. It only had room for one fan which was the back exhaust and that's it. It didn't even have holes for the power supply's intake fan! It was my fault for not researching enough and buying something so cheap. Then I did a little research and came across this case. It is only 50$ but has everything I want. I've seen PC builders on youtube build with this case and they all had great things to say. So the first thing I like about this case is obviously how much airflow it allows. It's an interesting design because there are holes all over the top, all over the bottom, and all over the front and you can install 4 fans if you wanted to (2 up top, 2 in front, 2 in bottom) in addition to the included exhaust fan at the back making it support up to 5 fans! Now with all those holes you might be thinking this is going to be an ugly case but as you'll see in the pictures this is not the case (pun intended) and it has very sleek looking dust filters to cover the top, front, and it’s not obvious from the picture but it has a filter on the bottom as well. I was pleasantly surprised to see that the filter is magnetic which made removing them to install my fans a breeze (pun intended). I also imagine cleaning them when they get dirty will also be very simple. You can simple remove them and just rinse with water. One tip when installing fans is that since there’s air holes all over, they actually made a very small indentation around the holes that you should screw in your fans. These “guides” are hard to notice but if you look closely you’ll see them. They have space for 140mm and 120mm fans depending on whatever you want. Air is able to easily flow through the filter so my air flow issues were resolved! The case also looks very nice in my opinion. I have the black model just because that’s what my nephew wanted but in review videos I’ve seen, the white one looks very nice as well. Cable management at the back is pretty good too and the case comes with a lot of zip ties. The filters I mention above are also very aesthetically pleasing. The power button, 2 USB ports, headphone jack, and speaker jack are on the side which I don’t mind. The interesting thing is that this IO panel can be unscrewed and moved to the other side which is nice. The clear side panel is acrylic but it’s a 50$ case so it’s fine. It doesn’t look bad at all. There’s also room in the cable management area for a 3.5” hard drive and 2 SSD’s inside the main area which is very good. Overall the case was pretty simple to build in. It’s designed very well to maximize airflow while looking great. I think this is an excellent case especially for the price. If you’re in the market for a cheap but good PC case, then you my friends have stumbled on a cheap but GREAT PC case. I would highly recommend this case and am willing to do even more expensive builds with this case in the future. One final note I’ll add, I built my nephew’s pc with a Ryzen 5 1600 processor and RX 480 gpu reference model targeting 1080p gaming and the heat in my old case with that one exhaust fan was reaching around 87 degrees C. After I added two intake fans in the front and one exhaust fan in the top along with the back exhaust fan that comes with this case my temperatures went down into the mid 70’s while gaming which is great. If you want looks as well as functionality for a great price, go with this case.

If you are looking for a cheap, functional chassis to put together a budget build or an AI box, this case delivers strong performance for the price. The all-black exterior and interior look clean, the airflow is surprisingly solid, and all the included mounting hardware matches the sleek black look. It gets the job done for lower-end setups without breaking the bank. However, a few design choices create unnecessary friction while working on or moving the system. The interior is completely black, which sounds great visually, but it makes cable routing and component alignment remarkably frustrating. Unless you are building inside a bright, well-lit room, seeing small headers or threading cables through the dark cutouts takes extra effort. Another annoyance is the PCI expansion slot retention bracket on the back. Instead of allowing you to unscrew individual expansion slots to swap or clean a GPU, you have to undo a massive back plate to access any of the card slots. While it gives total access once off, it forces you to turn far too many screws just to service a single card. Finally, the magnetic dust filters are a double-edged sword. Being able to peel them off in one second for cleaning is convenient, but the magnets are too weak. The filters slide out of place every time you shift the case around, and pets can effortlessly hook a claw underneath the edges and pull them completely off. Pros and Cons Pros: Excellent value for a budget-friendly PC build Solid airflow performance considering the price point Sleek aesthetic with matching black screws and hardware Cons: All-black interior makes it very dark and difficult to route cables without bright room lighting PCI back plate setup requires removing a large bracket rather than individual component screws Magnetic dust filters shift out of place too easily and pull off with minimal force Final Verdict: This is a solid, cost-effective choice for lower-end systems, and I would use it again for budget projects. Just be prepared for a dark working space during assem

Great value micro-atx case. Its cheap and works. Like the compact size and the fact it came with screws, spacers, ties and a fan. I like the magnetic dust filters concept however BEWARE of the very rough and pointed edges which could cut you while handling them. The power button on the side panel worked for me but could be a problem with other builds. I was barely able to fit two Thermalright TL-C14C 140mm fans in the front with the default front facing power button+LED panel layout, while managing the power/led/usb cables in between the two fans to the backpanel but it was a very tight fit. You can move the power panel to top bottom or rear if you have the space. My Thermaltake Smart 700W PSU blocked the bottom though. While the top was blocked the height and size of the Thermalright Phantom Spirit 120 SE Black CPU Cooler. And the rear was blocked by case fan and no real access for cable management through to the back panel. So I had to make the front faced orientation to work, which it did. All in all I am happy with the value of the product.

Considering the price point, this is the best case I've ever used. Sure it isn't the best case in existence but nothing at this price beats it. Cable management is decent, it has felt plenty sturdy to trust with my components and has more space for fans than my motherboard does headers. Cooling is only limited by my issues with limited fan headers, not the case. Fit my 9070 XT no problems as well and the tower air cooler. ONly issues I've had are the weak magnets on the dust filters, and a few sharp edges that I ran into during install. Also only 2 hard drive mounts isn't ideal but hasn't been a problem.

Great for the price. The metal is pretty thin and I'm sure the acrylic panel with scratch easily, but if you're just looking for a home for your Micro ATX motherboard and a GPU then this is a great budget pick.

Overall great! Major and unforgivable problem: the covers for PCI cards are soldered on the case and very hard to remove especially if the motherboard is already installed. I have to almost break the case to detach it to install a PCI network card

This is a pretty good case to setup a tiny pc. I had read a couple of mixed reviews, but probably came out of people trying to do too much with it. I used a Thermalright Assassin Spirit 120 SE, GeForce RTx 3060Ti, the two 120mm Thermalright fans and another two 140mm Thermalright fans on these, with a B560M Power mono and it freaking rocks. Everything fits very nicely and the setup was very easy, with tons of backspace to put the cables in and hide them from the setup. I love it, it looks clean and its airflow is better than I expected to be. I didn’t put any extra lights on it, I don’t think they were needed, but if you put some RGB Fans is going to look pretty cool! My Micro ATX motherboard was completely compatible with this, so I’m happy!

So this q300l case was released by cooler master in 2018 This Case was q500l 2019-2020 predecessor This case has holes in top, front and bottom I had 5 fan laptop cooler on which this Case is sitting right now, my laptop had fan issues so now it's used for PC case cooling I have attached 2 arctic fans 140mm 1600rpm and 120mm ,1200rpm in front for intake 2 coolermaster fans one for exhaust (xtraflow 1500rpm) backcand one for top ( 200-1000 rpm) 1 circle fan (1000-1200) rpm My PC temp with just one exhaust fan was around 45-55 during normal usage and CPU temp was around 64-74 degrees on normal to heavy load and gpu temps were 50 - 60 degrees CPU fan was spinning at 1500 rpm max After bumping up AMD wraith Cooler fan to max fan speed of 2600 rpm in bios settings, my CPU temps went down to 50 degrees. After installing all the fans, My case temps are 36-39 degrees My CPU temp is at 42 degrees normal and at 57 on load. If your buying this case get at least 2-4 fans You can 140mm fans or radiator in the front only On top only 120mm can be attached properly I could be wrong depends on brand and size of 140mm fan My arctic fan screw holes weren't able to match on top of the case. The magnetic dust filter on top and front can be cleaned easily. The side panel is acrylic, fingerprint magnet. 2 USB 3.0 jacks in front Mic and headphones Jack with HD audio but can only do 5.1 channel not 7.1. I had to attach my 7.1 channel headphone in the back Cable management very good Lot of spaces in the back. If you have radiator then your CPU temps will get better than mine . This case should cost around 3500 rupees But I had no choice but pay up 4500 rupees Cuz it I needed it urgently. This pandemic has really screwed PC enthusiast when it comes to pricing of PC components. 4/5 My PC specs AMD 1300X 3.8ghz (2018) Sapphire pulse RX580 8gb OC lite (2020) 😑 Ballistix red 16gb (2020)😑 Cooler master 550 mwe psu (2018) Acer vgo monitor 144hz LG monitor 75hz

1) Cable management that does not suck, that's a big advantage 2) Can be placed under the monitor on the desktop, rubber pieces on the long side 3) With 3 PWM-driven chassis coolers it is a silent beauty 4) Overclocked graphics card temperature is below 65°, that's very nice airflow 5) The side panel is acrylic, not glass, which is so so, but pretty fine for a budget setup 6) Buttons and USBs can be rebased at any side, but I just kept them as-is 7) Very careful and lovely use manual, showing all necessary addons for different setups 8) Loved the included rubber pieces for easy placing of the SSDs Would definitely recommend it!

Goede kast met aardig wat mogelijkheden! Had zelf een kast nodig die niet te veel ruimte innam en niet al te duur was. Ik ben positief verrast.

O gabinete é ótimo e super bonito, o que mais me chamou atenção dele foi o design super compacto e a versatilidade de usar, mas apenas de ser bonito, ele tem os seus defeitos. O acrílico é super fácil de arranhar, enquanto eu estava mudando as peças do meu antigo gabinete para esse, eu deixei o acrílico encima da minha cama com todo o cuidado do mundo, porém, quando eu fui fechar o gabinete com o acrílico, eu vi um pequeno arranhão no canto inferior direito, de início eu não dei muita importância, mas com o reflexo da lâmpada do meu quarto eu achei vários e vários pequenos arranhões que só podem ser vistos na luz, eu simplesmente não entendi o que causou aquilo, já que eu tive o máximo de cuidado possível, mas para quem vai comprar esse gabinete, cuidem do acrílico! E de resto ele me agradou muito, acho incrível como a Cooler Master consegue fazer excelentes gabinetes com preços incríveis. Apesar de ser um gabinete M-ATX, tem como você colocar até 6 fans de 120mm nele que eu achei super top e bacana. Recomendo d+.
