Cooler Master Cosmos II


An outstanding look and tons of component space distinguish the Cooler Master Cosmos II PC case, but its high price and some design oddities may turn off all but the most affluent and patient builders.

Offers lots of space for 3.5-inch drives. Includes numerous fans, controller. Easy-to-open doors. Mostly tool-free construction. Attractive

Very expensive. Tall and heavy. Will not lay flat. Only three 5.25-inch bays. Hot-swappable 3.5-inch bays don’t support 2.5-inch drives. Potentially tricky cable and wire storage

Corsair Obsidian 900D vs. Cooler Master Cosmos II


The Cooler Master Cosmos II debuted in 2011 to much fanfare. Indeed, it was the chassis of our dreams. It housed our precious Dream Machine that year, and was easily the best “super-tower” available. In 2013, the Corsair 900D came on the scene boasting...

Cooler Master's Cosmos II enclosure


Hot on the heels of our Antec P280 review, we've got another next-generation case in the lab with some mighty big shoes to fill. Today's object of techno-lust is none other than the Cooler Master Cosmos II—an "ultra-tower" chassis that seems a little...

The Cosmos II's family resemblance is uncanny. However, there are two important differences between the current model and its lineage that make us wonder if Cooler Master should have gone with a different name. The Cosmos II is quite a bit costlier...

Cooler Master Cosmos II Full-Tower Chassis Review


Huge, feature-rich cases are nothing new, but the Cosmos II from Cooler Master becomes one of the best - if not the best. The company touts it as being an "ultra tower", and after shoving lots of high-end hardware into one, we'd have to agree. But...

The great thing about the Cosmos II is, well just about everything.

Cooler Master Cosmos II Review


The classic Cosmos is updated for the modern market with the Cosmos II, the first so-called "ultra tower" case.

The Cooler Master Cosmos II is easily one of the best cases to enter our labs. It offer plenty of features, support, excellent thermal performance, and it just plain looks great. Much like its predecessor, the Cosmos II should quickly become one of the...

Cooler Master Cosmos II


Huge and beautifully designed ; Swing-out doors that can also be detached ; Lots of opportunities for cooling and cable management ; More drive bays than most people have drives ; Potential to sink through the earth due to pure size

5.25-inch drive bay release buttons don't seem very reliable ; Some fans in our test sample clattered ; Hot-swap drive bays are connected together and permanently connected to cables ; Fan controller isn't very accessible ; 3.5-inch drive bay locking...

The Cosmos II is big and beautiful. You'll need to put aside AU$369 and a lot of floor space — but, if you can afford both, you'll never regret it.

Humongous Case and Very Heavy


Excellent quality case, a tad bit expensive but you are buying a Ferrari of Cases. Only draw back is it weighs 59 lbs and more when you put your build in it. Worth buying if you have the money.

Nice case - it's huge!


I purchased this case for my 1st ever PC build. I like the design, especially the roominess of the case. This case makes my P8Z77-V Premium look small and has no issue housing the Noctua NH-D14 CPU cooler. I have a EVGA GTX 680 installed with rooms to...
