Dimensionally-speaking, the Cosmos S is practically identical to the 1000 in size. They also share similar overall design cues; the rounded panel edges, bars that double as grab handles and feet and hidden latch side panels. The S takes on a slightly darker hue, with more black and gunmetal in use rather than the silver predominantly found on the 1000. Cooler Master has also definitely done something about the little weight problem. With a mostly aluminum construction, the Cosmos S tips the scales at right around 29 pounds, much lighter than the 1000's 40-pound mass.

Steps have been taken to improve cooling on the Cosmos S. A third fan position has been added to the top of the case, one more than the 1000 has, although only one fan comes installed by default. Cooler Master has ditched the front panel door, leaving the mesh bay covers free to breathe as needed. The solid lower portion of the front panel has also been eliminated in favor of more mesh covers, which now comprise the entire front from top to bottom. The rear of the case remains mostly unchanged, with one 120mm exhaust fan, honeycomb openings above the riser slots and power supply mounted at the bottom. Levers to open the side panels and rubber grommets for water cooling tubing occupy the same place near the top of the case.

The top-mounted I/O panel is relatively unchanged, with four USB, headphone / microphone jacks, Firewire and eSATA ports hidden behind a sliding blank cover. The power "button" can also be found here, a slightly different design than before. There is no physical button switch, only a slight depression in the plastic which is touch-sensitive; definitely scores a point for coolness factor. The individually-wrapped mesh front bay covers are a carry-over from the 1000, although they now go the whole way to the floor. Each one has a fine screen behind the mesh to filter incoming air and can be moved around as needed. At the bottom we find a 120mm intake fan at the front of what appears to be a hard drive cage, a much different design than used previously. More on that later.

Now let's take a look inside the Cosmos S.
