great budget matx case.
I just built a PC for my daughter using this case, and as long as you're not going overboard with components, there's plenty of room. We used an mATX motherboard, and the case comes with a single 80mm fan in the rear. There's easily space for three more 120mm fans — possibly four, depending on your motherboard clearances. Airflow seems perfectly adequate, and the included dust screens are a nice touch.The motherboard tray is well-designed, with several pass-throughs in the corners and bottom. We routed all the cables behind the tray and back through to the motherboard, which made for a very clean build. RGB fans shine through well — lighting visibility is decent.This is a great budget case, but keep in mind that at this price point, the metal is thin. Don’t drop it or lean on it too hard — it can bend out of shape easily. I know some people knock the lexan panel, but if you keep your hands off it and use a microfiber cloth to clean it, you’ll be fine. Just avoid anything abrasive or it will scratch.We did run into a minor issue where the power button didn’t work initially — flipping the header on the motherboard resolved it. One other small gripe: the USB ports on the side panel are too close to the power button. If you plug in a USB stick near the power button, it’s very easy to accidentally shut off the PC — I did this a few times.Despite those quirks, there’s not much to complain about at this price. It’s a nice little case with good functionality and solid value.

Great value
For $40 I don't think this case can be beat. It looks great, can stand or lie on it's side, and has a modern layout with the PSU on the bottom. The thumb lips to take off the panels are thoughtful along with the included magnetic dust covers. Although the clear side panel is plastic you can't tell until you touch it. Great air flow in a small case. Plenty of screws, zip ties, and stand offs come with it along with one rear case fan. I put a mini-itx LGA 1155 mobo in it with an i7-3770 for a retro win7 build. My GTX 980 fits perfectly. The motherboard has an odd placement for the USB 3.0 but I lined it up with the GPU power and it doesn't look horrible. Plenty of room on the back side for cable management. My PSU is not modular and I was able to hide all the cords I didn't use back there. If you don't need USB C or other modern amenities this case is perfect. Obviously it's a good choice for retro builds with a modern flare. Cooler Master knocked it out of the park with this one.

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.

Not bad for $40
You get what you pay for. Cable management is okay, cooling is actually not bad (have to buy your own fans.) Super lightweight and compact, but it is serviceable for my little brother’s first computer. Looks okay and does what you need it to do.

front fan mounting
im no hater of this case , cable management is good , really spacious for a small case . the only beef i have with it is fan instalation. 140mm fans in front are the worst. hard to line up with the holes without getting out of align ,but you can do it with a little finaggling (putting it nicely ). other than this , its a really nice little case . thanks to all involved and MAY GOD BLESS ALL !!!!

great small form factor case, easy to install even being small.
I like the small size. With my fans and video card it cant really be any smaller. I had no trouble installing it even as a man with big hands. I like the clear panel. The fan it comes with it kinda silly. Not much air comes out past the case panel for it. Its older so no usbc so i added my own. I like the rubber feet on the side and bottom for use either orientation. I really liked the price! I would happily buy another. The power supply fits snuggly in the bottom, no extra room but it fits nicely.
