The Cooler Master Cosmos will set you back almost exactly twice as much as the smaller Cosmos SE. So Cooler Master is, looking at the price, going after a totally different market. While Cooler Master has done an excellent job in creating a case that looks just like the bigger chassis, some of the features found in the bigger chassis had to be left out. You won't find the hot-swap bays, advanced power/IO panel, or fan controller, but the Cosmos SE offers excellent liquid-cooling possibilities as long as you are alright with sacrificing expandability, loads of space for hard drives, an extremely well-engineered modular drive-bay system for six out of the eight hard-drive bays (I got a feeling we will be seeing more of this system in future Cooler Master offerings), and four fairly quiet fans. Installation is a breeze thanks to the functional hard-drive trays and easily removable 5.25" drive bays, while cable routing is a breeze as well due to loads of possibilities and space behind the motherboard tray.

One of the issues with the Cosmos SE is the space, or lack thereof. It will fit high-end components, but you have to watch what CPU cooler you install, and a wide motherboard (as wide as the one we used in our review) will partially block the grommet-covered cable-routing holes, making it a tight fit if you fill the chassis to the rim. All of that may ad a bit of complexity and time to the build, but the chassis is what one would expect: a smaller Cosmos at a smaller price for a larger target audience.
