Cooler Master MasterBox Q300L Micro-ATX Tower with Magnetic Design Dust Filter, Transparent Acrylic Side Panel, Adjustable I/O & Fully Ventilated Airflow, Black (MCB-Q300L-KANN-S00)

This budget PC case is an absolute dream to work with! Despite the affordable price, it offers plenty of space inside, making it easy to install all your components without feeling cramped. The back plate has ample room for cable management, allowing you to keep everything tidy and organized with minimal effort. Whether you're a beginner or a seasoned builder, this case provides excellent value and a hassle-free building experience. Highly recommended for anyone looking for a solid, budget-friendly case!

Look, let's jump to the point: this thing is difficult to build in. If you are putting together a desktop with larger components or more storage, I would look at something else.However, it's a very economical case with *acceptable* cable management, and if you are building something like a NAS, HTPC, server, or any PC really with a low-profile cooler or AIO, it will go together in less than an hour, especially if you don't care about what you see through the window.Here's what I managed to stuff in it in a much longer timeframe:-i5-whocares-it's-from-2019-asrock mini-itx motherboard-Noctua NH-U12a tower cooler-geforce rtx 4060-2x sata SSD's-4x 120mm case fans (one of the two available CPU cooler fans)-sleeved PSU cable extensionsPros:- compact, pretty standard construction: riveted together, metal and plastic side panels- you can move the IO panel around- pretty flexible fan placement with 120mm fans- pretty flexible SSD mounting, even more if you're willing to use mounting tape- nice dust filter config and great airflow, although they do move around a lot handling the caseCons:- very little space between top of motherboard and top of case. Mounting a radiator up top would require splitting the radiator and fans both inside and outside of the case. Putting an exhaust fan above a tower cooler would be impossible as well without putting it outside the case- because of this space, it's also difficult to connect an 8-pin CPU connector at the top of the motherboard. If you have a modular PSU or extension cables, connecting the cable before installing the motherboard is essential but also cover the mounting hole on my motherboard- rear exhaust fan mount not "countersunk", it will be very close to whatever cooler you use, which is why I could only use one CPU cooler fan- cable management space is pretty thin- one HDD mount which cuts down even more on cable management space if you actually put anything on it.Overall it's a good case for what it's designed for, and v2 is supposedly better.

I feel like this case doesn't get enough love, because while the upgrades over the original are minor and the styling is a little outdated, it's still a great refinement over its predecessor. It's my go to case for pre-builds currently because when it comes to new and average users who aren't the most well versed in pcs it makes it easy for these types of users to approach their builds without feeling overwhelmed while offering all the features you'd expect from a newer case. The case is compact and doesn't take up much space. The front gives you easy access to all your components including the power supply and cables. You're given quality dust filters. You actually get a usb c port on the top which is hard to find around this price range. The rear is spacious and makes cable management easy. The overall construction is very solid and doesn't feel cheap or flimsy. The tempered glass panel is a very welcomed addition over the acrylic it originally came with. The pcie slots are screw in and not irreplaceable pop offs. It checks most boxes and is extremely easy to build in even if you are new to this hobby. As a starter case and even for experienced users I think the Q300L V2 still manages to stand out.

I was looking for a small mATX case to use with some older parts that I had in storage (I will list all the parts at the end for reference). So far it's worked great and I didn't really run into any major issues. I like how compact the case is and I was able to fit it under a small table. The computer is for light gaming and web browsing, so thermals have not been bad.Putting all the components together in the case was pretty straight forward. I found it a lot easier to work with than a small ITX or even a full ATX build. I didn't install any fancy or exotic parts (AIO/Water Cooling) and kept it simple, which I feel helped a lot. I like the dust filters that come with the case and the design on the filters give it a nice look. Since I am using a simple CPU (9400F), fan noise is non-existent since the processor doesn't generate a lot of heat. I'm using some Corsair RGB fans (x2 in front panel/x2 top of case), which look great and have them configured to silent in iCUE.There are a few issues so far with the case: 1) Stock outtake fan stops spinning randomly. I have it connected to the motherboard and have set the fan to full speed, but it does not fix the issue. I've also tried other fan headers on the board, but the fan continues to stop spinning. Not a big deal since a basic case fan is inexpensive, so I will be replacing it. 2) The Plexiglass can scratch easily if your not careful. I debated taking off the plastic film for this reason, but decided to remove it in the end. Glass would have been better, but for the price, you really can't complain. 3) Expansion slot covers are attached to the case, so removing them can be a little tricky. I ended up bending one of the slots a little bit, but was able to fix it by bending it back into place carefully. Finally, the only other thing that would have been nice is to have an all-in-one front panel connector. This would definitely help inexperienced builders to easily connect the front panel ports/power to the board without much struggle.Overall I'm happy with the case and do recommend it for anyone looking for an inexpensive mATX build that will look great.PC Specs:AsRock B365M Pro 4 Motherboardi5 9400F8GB TeamGroup RAM 2133Mhz (two modules)RX 570 4GBTeamGroup SSDEVGA 650W Power Supply ATX (non-modular)ID Cooling Low-Profile CPU Fan (IS-47-XT)x4 Corsair SP120 RGB Fans with Commander Core

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.
