Cooler Master MasterBox Q300L TUF Gaming Alliance Edition Micro-ATX Tower with TUF Aesthetic Design, Transparent Acrylic Side Panel, Adjustable I/O & Fully Ventilated Airflow (MCB-Q300L-KANN-TUF)

This is an excellent budget case for an mATX or mITX build. Was easy to route cables for effective cable management, even when using a non-modular PSU, as there is plenty of room behind the motherboard tray. Furthermore, this case will accept a “full-width” mATX board, as it has a full set of stand-off holes for both mATX and mITX. Airflow is excellent and, for a low power (e.g. ~ 35w TDP CPU + iGPU) build, you only need your stock CPU cooler and the single rear chassis exhaust fan (which is a good quality CoolerMaster rifled-bearing fan). The case comes with top, bottom and front removable dust filters which, for the top and front, are magnetic fit. This is, however, an inexpensive case, so don’t expect RGB fans, fanbus controllers, tempered glass (the glass panel is acrylic), or heavyweight construction. What you do get is a handsome enough looking case, with lots of fan and radiator mounting options, great airflow and dust filtering, that is easy to work in.

I bought this to hold an older i7 motherboard I acquired. The system is great. The case has many features that surprised me. You usually don't consider case features to be a big selling point for day-to-day use. That's where the surprises come in. The magnetic dust covers work interchangeably and are so easy to remove, clean, and then put back. They hold up well. The side plastic is durable and holds up to use. Doesn't get to dusty. The most fun I had with the case is that the whole thing is perforated with holes. This becomes handy because you can mount as many or as few fans as you like anywhere. You can also mount switches and buttons utilizing the perforated holes as well. When you add the magnetic dust covers back you never notice a thing. The design and quality is more than what I expected from a Cooler master case. They really outdid themselves on this one. I have owned three cooler master cases so far and each one I bought for the price and exceeded my expectations. Good Job. The one caveat I would say is the bottom case has a thin, metal dust cover, that seems to fray at the edges. On carpet or along any surface it seems to come right off and snag on anything it is placed on. It becomes annoying if you move it around alot.

I have built pc's in over 30 computer cases in the last 5 years most around $100+ and I have to say this $50 case is not missing that many features of it's more expensive counter parts. Other then tempered glass. Pros. Great Airflow. Very nice design that works with most hardware colors. USB 3.0 on the front. Very easy to work in. 2x Internal 2.5" SSD mounts so you can see those drives in action! Fits most power supply's with no issues. No sharp edges. No case flex, feels very solid. Con's: Has a weird way of installing the power supply that can make it harder to plug and unplug. Acrylic side panels are easy to damage and scratch even when cleaning with a microfiber cloth--- Not much of a con at the asking price though. Final thoughts, For the price is is one of the best MATX cases that I have ever worked in. It is packed with allot of feature that you often need to spend more to get. Airflow is great in this case due to the whole front is a intake with very little blocking the airflow's path. If you are in the market for a solid case and don't want to spend a ton this case is for you.

Very well worth the few extra dollars over the base case. EXCELLENT airflow for a micro atx case. I still have my Vega 64 at 310mm and this case took it with enough room for 3 nice 120 fans in the front. Despite not having a PSU shroud my setup only includes 2.5" SSDs and an m.2. My PSU is only semi modular but the window tint and design on the window make this a non issue(I have rgb everywhere and this case handled the cable management in such a good way that it may be my cleanest build yet) oh 1 other thing people look for when buying smaller cases is what heatsink people are using, my Cryorig H7 Quad Lumi (what a name) fit with plenty of space (154mm tall I think) awesome job cooler master and thank you amazon drivers!

This is a awesome case. The materials feel nice, and it comes with everything you need. The case is easy to work in, and has features for any build (it can actully support 2 graphics cards). The case looks nice (espically the TUF edition). If you want a budget case that looks good, and is easy to work in, then this is a great case. The only 2 downfalls are, A, the cable managment behind the back panel is pretty bad, and looks like a mess but is not visible from the outside so its fine, and B, this is directed at some people, there is no slot for a dvd player. But other than that, this is a great case.

This is a really awesome case. It is built like a Chevy. It will never fail. I got this right on time. I went with the q300l tuf edition and it has plenty of room for what every you need in it. The cable management is phenomenal plenty of room. I just love how compact it is to. Very easy if you have to move it to a different location. It is heavy too. So it has real metal unlike most cases.

Pros: The case was not too bad to build in. there is enough space behind the motherboard tray for decent cable management. Form factor is nice and small. it fits on my desk without taking up too much space and is light enough im not worried about it being on top of my glass desk Cons: This is a personal thing but I don't think its a particularly good looking case. the acrylic side panel is going to get scratched easily and the front I/O cables made putting in 2 140mm fans kinda of annoying because of they way it is cable managed. The dust Filters: These are probably fine if you dont have kids that can reach your computer, if you do these will not last long. The idea behind them would make them easy to take off and clean but I feel like they are a bit che aply done like the rest of the case. Front I/O says it can be on a different side of the case but i dont think thats possible. would have been nice to move.

I have built my own computer for two decades and I like the simplicity of this case. No massive harddrive trays to clog up the air flow, a ton of places for fans, which I need to keep the fickle 3900x cool and I like the square symmetry. The other reviews are correct on the two negatives with this case: the holes for the fans screws are too small and the metal mesh is too restrictive in front of the fans which kills airflow. Do yourself a favour and, unlike me, take a minute to drill out the fan screw holes. I just forced the screws through with a drill and now they are not coming out. I also cut out massive holes for the fans with a jig saw, with no structural problems. The external magnet filter more than protects the fans and the new fan holes makes populating the case much easier as you can get your hands in from the sides (minus the sharp rough edges of my self made holes). Coolmaster should make the metal mesh have holes that easily pop out with a bit of pressure. Oh and if you are a fan of the biggest fans possible, even though they say only 120mm fans can fit on top, you might be able to shoehorn in two 140mm fans, although they will be pressed right against your MOBO. I had to cut the clip off my CPU power lead to get it to seat properly with the 120mm top side fans. They use the same perforated metal mesh on all three sides which means it has the necessary 140mm fan mounting holes. It sure does look pretty with RGB fans puking rainbows everywhere. I seriously just use Asus Aura to show me the temperature range of the processor via the colours. [Update July 14th, 2020] Turns out the fan screw holes are only too small for the top fans, all the other ones were fine. I managed to squish in a Phantech CPU cooler and used a jigsaw to remove the metal mesh in front of six of the fans. The case is super light now and the RGB fans are much more visible.

The case is awesome and its very easy to assemble. You can check out my video on my YouTube Channel how I put everything together.

Ok

I didn't expect the case to be of premium quality. Nice look, but feels cheap. Great for my Mini Itx build.

Super
