Nice.
It's a nice , entry level builder's model. No real bells and whistles , just very well-thought out. And it has nothing but airflow. The 2 fans that come with it are cheap as all getout , run of an adapter , not a motherboard hander , and don't have a 3 or 4 pin plug , they'll get you into the argb game , but just enough to immediately look for proper replacements. If you're new to this PC building stuff , the case is fantastic with all rolled edges , no weird arcane steps to be functional. And for anybody that ever had the Darkflash DLM-22 , it's about the same size but with one distinction , it does what a good case should do , flow air and look reasonable doing it. If you're on a budget that's slightly less than what this costs , wait a bit and get it when you can , it's worth it.

Great Micro-ATX Case Especially For 1st Builds
Listen, I like it. It hasn't failed on me. Pros: Spacious (This things fits my 6900xt reference just fine) Comes with 2 front case fans that aren't too noisy Easy to take apart (tempered glass, front panel, back panel) RGB (because.. lights) Tempered glass so you can look at your bright shiny things Con Cable management is a pain (could be a "me" thing, but it's pretty tight back there) I bought this case for my first build last year (5600g build) and it hasn't failed yet. Through my nervous reopening and upgrading parts (yeah, I still get nervous opening up my built system), it's still running fine. I recommend

Just like my old one.
I got this after my old one's glass shattered. It has been a good case to me and I recommend it. It has some good cord/cable management and it has fantastic airflow from the front. It's perfect size to move, not too big or small. Highly rexcomend this as it comes with the ARGB stuff already hooked up. All you need it a MOBO with the right headers.

Nice case, but very thin gauge metal
It's very easy to build in and neatly manage cables. Plenty of room for large video cards or more complex cooling. The fans that come with it are quiet, and the included RGB controller is nice and simple, and retains your setting when unplugged. Airflow seems good - I have the mesh front version, so this may be more of an issue on the clear front model. If you have a larger or a modular power supply, it will get cramped in the basement if you're using the removable hard drive case. If not, plenty of room for a front mount radiator or to hide cables. There are also plenty of 2.5 mounts for SSDs, two on top of the basement, and two on the back of the motherboard tray. The only real downside is the thin gauge metal, mostly noticeable on the back by the motherboard io area and rear fan. This makes installing the io shield a little more challenging than normal, but getting a (quality) io shield in the firms it up some, and adding a rear fan helps even more. But it is the thinnest structure I've ever had on a name btand case. I would be more disappointed if I had paid the full Amazon $100 price new, but for $60 on like new condition, it's worth it and I can get over it.

The best case in it's size and price class
I've bought multiple of this case for different micro-atx gaming computers, and I've never been disappointed. Box is standard, foam is standard, nothing to complain about regarding the packaging. The included argb fans are good, depending on the day you may get a splitter or a dedicated hub, both are fine. Fans are 3 pin power so nothing too crazy, I'd say if you feel the need to upgrade the fans this case may be worth skipping, as the fans themselves are a big value add. Argb is standard 3 pin motherboard header, and there should be options for daisy chaining more fans or strips if they are the same standard 3-pin ARGB Hard drive cage is removable and easy to mount, power supplies are easy to fit, there is a very generous amount of room to cable manage in the back, and cutouts are placed appropriately for any cables you may need for the motherboard. Hard drive mounts for 2.5" drives on the power supply shroud and in the back are a bit unorthodox but fine, I would not recommend spinning drives in anything but the hard drive cage as there is no hard connection to the case. They are secured via the included screws into the hard drive itself and then wedged into rubber grommets which are wedged into the case holes, so for SSDs this is a non issue. PCIe slot covers are not replaceable, but that's not a deal breaker at this price point. AIO support on the top of the case is limited to a 240mm. 2x 120mm or 140mm fans will fit fine by themselves as there is enough space above the motherboard for either. For front mounting any fans, either 120mm or 140mm will fit, and while 3x 120 will fit, there is not enough extra space on the top or bottom for a 360mm AIO, so don't try it. For bottom routing the tubes of either a 240mm or 280mm on the inside of the case, you may need to remove the hard drive cage to fit the cables, otherwise it should be fine with top routed AIO tubes. Overall at the original price of $65 I'd say this is a no-brainer, at $75 it's still a good option, but at $90 I'd pass as there are much better options within that price class.

Built this with a b450m bazooka max, r5 3600, rtx 2060. Really solid design with good airflow. The two included aRGB fans, tempered glass side panel and magnetic filter on the top are a nice touch. The fans come with an RGB controller as well which makes changing the colours/patterns easy to configure. A few notes for people looking to buy: - The PCIe slot covers have to be permanently removed for the GPU installation, so make sure you remove the correct ones. I'd also recommend removing the slots before installing the motherboard since the slots have to be pushed inwards to be removed (potentially damaging the mobo if you're not careful). - The front fans aren't PWM, but you can use 3-pin fans on a 4-pin header, you just won't be able to control the fan speeds. - The cable routing grommets are pretty basic, they're just holes in the case (no rubber grommets that are in more premium cases). - The RGB controller is the only way to change the fan lighting, so you'll either have to open up the case to use the controller every time you want to make changes, or connect it to the reset button in the front I/O for external access.

Ottimo airflow. Lo consiglio

Me encantó el gabinete: es súper espacioso y viene muy bien seccionado para colocar las piezas. Incluye cubre polvo, la ventilación es excelente, y se agradece que los ventiladores tengan iluminación personalizable. Además, trae cinchos que facilitan muchísimo la organización de los cables durante la instalación. Muy satisfecha con esta compra.

uncomfortably small if you're dealing with lots of cables and a big hand. I'd save up more and get a mid tower instead.
