Solid Case with some things added and others removed
This case came well packed and protected.Solid feel, not flimsy.Plenty of room for cable management.The EM plate fits very snugly which prevents it dislodging when installing your motherboardExcellent airflow due to magnetic filter covers on top, bottom, and front.Nice rubber feet on bottom and back side (in case you wish to mount case in 'desktop' position)Comes with USB type 3 connectors on front plus USB Type C and a 3.5mm audio output jack.The front panel harness connector is a single modular plug instead of individual wire termination which simplifies its installation, however there is no reset button or storage activity LED on this case.NOTE: the harness for USB-C terminates with a male USB-3.2 connector ( See attached photo) which requires a USB 3.2 header on the motherboard, or an adapter to convert USB-3.2 male to USB-3.0 header (hopefully your motherboard has two).Otherwise you will be forced to connect the USB 3.2 male to an adapter converting it to a standard USB-type 2 header which will reduce the speed of the port.

Perfect for a budget build for my mom
This is my 2nd full build in 2 years using pcpartpicker. This one a budget build for my 80 y/o mom to get her up to Win11. The feet on the side are weird, as I can't imagine you'd want to rest this on its side with a monitor on the glass. I could remove the feet for a tigher fit, but I suspect that might create more problems.I have no concerns about Airflow as I only installed a low end processor that I don't expect will get too terribly hot.I saw one reviewer struggle to get the power supply screwed in, but you have to remove a bracket to mount to the power supply first. It might have been easier if the bracket wasn't attached first.Overall, quality seemed fine. Cable management was a breeze. All mounting screws were included. Honestly I would have been fine with a metal (or acryllic) side panel over glass to save a couple of more dollars since this is a cheap case, but that's just me.

Decent budget case
I picked up the Cooler Master Q300L V2 to use with my Plex server. I was looking for an inexpensive case that would not take up too much space but looked good. This fit the bill.Pros:- Ample space for cable management behind the motherboard tray- Compact design- Space for a 240MM AIO (front mount)- Tempered glass side panel- Plenty of cable pass-throughs- Supports 120 and 240 MM fans- Front panel USB C- Can be used both vertical and horizontalNeutral:- Pre-drilled fan holes smaller than most case fan screws (120 mm fans)- Some restrictions on component sizeCons:No basement"pop-out" PCI slot coversMetal feels flimsy (it held up fine for the build, but I could easily see it getting bent if I wasn't careful)Included case fan is very basicThe Cooler Master Q300L V2 is a good choice if you are looking for a compact case at a budget price. The case is similar to the $20-dollar cheaper original Q300L (and uses the same chassis) but adds a USB-C connection to the front panel and replaces the acrylic side panel with tempered glass. They also updated the magnetic filters to a new design. There is plenty of room behind the motherboard tray for cable management and disk drives - there are mounts for one 3.5" and two 2.5" drives.Additional case fans are a must as the air holes in the case walls are much smaller than the printed side of the magnetic filter would have you believe. I bought a 5-pack of Antec P12 120MM fans to go along with this case and mounted two front intake, one rear exhaust, and two top exhaust. That, along with my CPU cooler (Cooler Master 212 Hyper Black Edition) does the trick. Idle temps are around 35-36 Celsius for a Core Ultra 7 265k using stock settings with a 24 Celsius (75 Fahrenheit) ambient room temp. Under load (Cinebench R23 multi-core test) some cores peaked at about 82 Celcius but in general the package was in the high 60s to mid 70s. While the pre-drilled fan holes were too small for the fan screws, the case air holes were perfectly sized and actually provided more flexibility for fan mounting.There are some restrictions on component size, but they are well documented. I did not have any issues fitting any of my parts. I did see in an online review (and verified with my build) that even though you can fit a bottom fan in the case, depending on the size of your PSU the cables may be in the way.Building in this case was OK. The lack of a removable top and the limited space once components were added made running some wires more difficult. I will note that if I had to do it again I would have added components in a different order. For example, with the PSU installed it was harder to connect the back-of-system plugs (HD audio, fans) to the MicroATX board I used as it was very close to the connecters and limited the approach.All in all, I would recommend this case if you are in the market for a good looking, inexpensive, compact case for a budget or even mid-range build.

Very worth the Price
For 38$ you cant do better. It's 38$ so yes don't expect 100$ worth of stuff. It's EXACTLY perfect budget case. So yes you get one fan but you get a solid case. Clean glass and its light. The magnetic dust covers slip off super easily when handling the case so if your gonna move it alot I suggest a little hot glue to help that stay more on. Or just be careful when you move it. I tend to move my pc around alot from house to house. This is a solid buy with plenty of space.

Perfect mATX case
Used this case as my first PC build. I wanted a small case to fit in a shelf by my desk. The dimensions were perfect without choking the air.It’s mainly cooled by 2x140mm Artic P14d and 3x120mm Artic P12s. Very good airflow, I used ChatGPT to help me optimize the fan curves for the most optimal cooling configuration. I was able to fit 3D printed air ducts to assist in cooling.Case looks great and no issues with cables.
