Cooler Master Steel Mastercase Pro 3 Micro-ATX with Freeform Modular System, Sliding Clip-and-Click Panel and Modular Dual Chamber

In India you cannot find a decent mini itx case cheaper than this. CPU cooler clearance is 68mm around. I am using a noctua NHL9 am4 which is 35mm in height. AMD ryzen stealth cooler(short aluminium base) also works perfectly. Ryzen spire cooler (tall copper base) just fits but it may struggle to take fresh air as it goes very close to the underside of the PSU. 120mm AIO is also possible but not recommended. I replaced the front cooler master fan with a arctic one. I mounted one 3.5 inch HDD at the floor near the motherboard and 2xSSDs on the DVD tray, 1 SSD under the DVD tray. All are running cool. It is better to remove the side tray and use that space for another 120mm fan.

I purchased this from a local store. It is absolutely superb. It allows for the best degree of customization. Points to note are as follows:1. It's huge. Which means getting cables from the PSU to reach the various components (or any connecting cable in general) might be tough.2. It's huge. It needs adequate height, depth and width (since the doors open sideways) for best accessibility.3. It's huge. It has enough slots to fit in a number of components (12 HDDs, 8 fans, etc) but your PSU and MoBo need to be able to support an equal number of devices. Else, the level of scalability it offers is kinda wasted.4. It's huge, needs a lot of cooling. But if you wish to use the on-board fan (as well as LED) controller, you'll need to purchase fans that are specifically made for this case. Normal 4 pin PWM fans can't be connected to the cabinet. I'd recommend giving the controller a miss, and letting the MoBo do the fan controlling via PWM fans.If you have the above stuff figured out (and the money), just go for it. A case like this won't fail you for years to come.

Heavy and bigger than i expected

Very good build quality. I had a broken plastic hinge in HDD cage, The seller send me a replacement piece from CoolerMaster.Overall I am happy with the same. I do feel like I should have opted for 900D. But The look and design of Cosmos II is definitely much better than 900D !

Best HTPC case for mini-itx boards. Built quality is great as ever by Cooler master. Great service by amazon, received the package within two days. A little over priced though.

Amazing little case, can cram in a lotAs with all mini cases better to plan build ahead and assemble sensibly

Case os good but packing is really bad. Case gets Damaged while shipping overall all good compact case but hard to work in.

I built a powerful gaming machine inside this most awaited some it cases! Good built quality, quiet fans, ample space for cable routing. The side plate for recounting hard disks is very useful.
