This is by far the best MicroATX $60 case on the market. Comes with 2 ARGB fans for that price. I got the mesh but they do have it in tempered glass front. Both case have a tempered glass side panel.Pros:1. The 2 included fans are ARGB. Also has room for up to 6 120mm fans. 3 up front 2 on top and 1 in the back.2. Plenty of room for SSD's and 2 3.5 hard drives. Cage can be removed also. They only include 2 ssd's mounts which some might say is a con.3. Cable management is good and they do include zip ties.4. Plenty of room for a size-able video card.5. Solid construction high quality and I never cut myself on anything sharp lol.Cons:1. Not a fan of the ssd mounting as I was confused on how it worked.2. No rubber grommets but for $60 I can see why.3. After putting video card there is very little room for it to breathe. There is 2 places to mount ssd's under the video card why? I have no idea as it would make the video card work harder for airflow.4. Dust filter under power supply is removable but, is way harder to remove as it is not the side in type. Top air filter is magnetic why they could do the bottom they same is beyond me.5. Tempered side panel does set flush with case but be careful when taken it off. Nothing to hold it in place after you remove screws and will fall. Be careful! Tempered glass can break if you drop it on a corner.I really like this case as I believe it is a nice case for what you get for the price. I would like to see in the next version Cooler Master make the bottom dust filter either side in and out or do it like the top with magnets. Cheaper version without ARGB fans. Maybe make it in white. Options would be nice like rubber grommets.

Pros:Let me start off by saying that this case really brought together my “best bang for the buck” system I just finished building. It has ample space to throw in you m-atx mother board and plenty of cable routing options to cable manage till you heart is content. It includes an RGB controller for the fans it comes with which is really cool for something at this price point. It has ample room down below to slide in your PSU and you can even remove the hard drive cage to cram as much cables (non-modular PSU) or to allow easy access to plug in cables to your modular PSU. The case has ample room for airflow (make sure to buy the MB311L case for the mesh front!!!) and a removable top and bottom PSU dust filters. The tempered glass side panel provides a great view in and screws in and out with ease thanks to the thumb screws.Cons:First off… PLEASE MAKE SURE YOU REMOVE THE APPROPRIATE GPU REAR SLOT COVERS BEFORE YOU INSTAL YOUR MOTHERBOARD PERMANENTLY. The rear slot covers need to be punched out into the case for your specific GPU/mobo arrangement. It’s a sad cheap trick and kinda pathetic that its a punch out and done deal. Besides that, the panels are a bit flimsy but that’s kinda expected from a case at this price point. Also I kinda wouldn’t have minded some sort of fan at the rear for exhaust… but whatever.Overall it’s the best bang for your buck case out there and I’d recommend it to anyone doing a budget to midrange build any day of the week.Comp specs:Ryzen 5 3600xtGTX 1660 superAsus TUF gaming B550M-PLUS AMD AM4 Micro atxCorsair Vengeance LPX 16GB (2 X 8GB) DDR4 3600 (PC4-28800) C18 1.35V Desktop Memory - BlackCooler Master MPY-5501-AFAAG-US MWE 550 Gold Full Modular, 80+ Gold Certified 550W Power SupplySamsung (MZ-V7E500BW) 970 EVO SSD 500GB - M.2 NVMeCooler Master MasterBox MB311L ARGB Airflow Micro-ATX Tower with Dual ARGB Fans, Fine Mesh Front Panel, Mesh Intake Vents, Tempered Glass Side Panel & ARGB Lighting System
