Inside the Cosmos SE
Covering the basics as we first glance inside of the Cosmos SE, we see the hardware tied to the motherboard tray next to what seems to be quite a bit of wiring. You may also notice at this point that this is more of a mid-tower chassis, just that the bars take it to the specifications for a full-tower design.
The front of the chassis starts out with this pair of 5.25" bays that will need the use of screws to mount things here, as there are obviously no tool-free latches present.
The six-bay rack seen here can house six 3.5" drives or 12 2.5" drives due to the offset screw holes in each tray. Also, if you remove the three plastic sections on both sides of the trays, these bays can all be removed, but the fans are attached to the front sections from the factory.
At the very bottom of the rack assembly, there are yet two more trays that will either hold a single 3.5" drive each or a pair of SSDs. To access these bays, you must remove the mesh section of the front bezel.
In the roof of the chassis, there is a single non-LED 120mm fan that Cooler Master sent installed. Again, this is designed for use with 120 or 140mm fans as well as dual radiators in each segment.
The motherboard tray offers a good sized CPU cooler access hole, eight wire management holes, and 14 places to tie up the wiring. Each of the standoff spots is labeled and a chart is given as to which to use for ATX, Micro-ATX or Mini-ITX installations.
At the floor of the chassis there are two thin rails with rubber padding for the PSU to set on, and there are two more wire management holes. Also there is a PSU extender bracket in use to offer a bit more room inside for larger power supplies to fit nicely.
The 120mm fan installed as the exhaust is also non-LED, and all fans are 3-pin powered, but also come with Molex adapters. As for the seven ventilated expansion slots, they are held in place with thumbscrews.
Behind the motherboard tray, there is already 25mm of space in most places without the bump in the door even coming into play. At the left, at both the top and the bottom, there are places that allow for a 2.5" drive to go in each for massive storage options in the Cosmos SE.
There is in fact a lot of wiring. There are four fan leads to tend two, two of which also have LED switch wiring connected. Then there are the front panel switch and LED wires, the USB 2.0, native USB 3.0 and the audio cable to deal with. All of them are long, and are black to blend into the build.
