Cooler Master Cosmos II 16 Bay XL ATX Ultra Tower Gaming Case with SuperSpeed USB & 5 Built in Case Fans No PSU Black


Sleek, Streamlined & Stylish all while melding aluminum, steel, and mesh into an elegant yet aggressive monster.  Equipped with dual sliding doors, optimized airflow design and aluminum side rails it'll keep that high level of performance that you want while looking epic. What I described is not that new Lamborghini but the Cooler Master's Cosmos II Ultra Tower Gaming Case.

Don't be disappointed, while others may bring their tiny, boring and ugly gaming cases to that next LAN party.  You, my friend, can bring the Cosmos II with its sheer size and epic presence you're sure to turn heads with this Ultra Tower.

Not only is this the super sleek Lamborghini, but it's also a hulking giant Hummer with a ton of expansion bays and a big enough housing to fit an XL-ATX motherboard!  Not to mention enough fans to keep temperatures down and performance up.

This Cosmos II Ultra Tower Gaming Case has it all, as any Call of Duty fans would say, don't bring that tiny knife to a gun fight. Bring a rig you can be proud of, the Cosmos II, instead.
