Cooler Master Cosmos SE Mid-Tower Chassis Review

Interior

The interior features the same stealthy paint job as the exterior, black fixtures and fittings and the only bit of colour showing is a motherboard stand-off and some of the cables. There is a good size CPU cooler mounting cut-out behind the motherboard and there are four large cable routing holes, each fitted with high quality rubber grommets.

In the back we have quick release thumb screws on each of the expansion slots, as well as a slight recess for the rear 120mm fan, that extra space will come in handy for those mounting rear 120mm radiators as you’re less likely to conflict with the CPU block.

The front of the chassis features two HDD bays at the bottom, the trays for these slide out at the front of the chassis behind the dust filter. Then there are six more bays above that which slide out from the side, all of which support 3.5″ and 2.5″ drives.

The top of the chassis features a 140mm exhaust fan, bringing the total pre-installed fan count to 4. All fans come fitted with 3 pin connections and removable 3pin to molex pass through adapters.

Around the back of the chassis we see there are a lot of cable tie down loops that will help keep excess cable in check. there are also a range of smaller cable routing holes above and below the motherboard that will be great for routing USB, HD AUDIO, 8pin 12v and similar cables.

While the side panel does add over 10mm to the cable routing space, I doubt you’ll need the extra room as there is already 25mm to play with and that should be more than enough for any build.

Above and below the HDD bays you’ll also find two 2.5″ drive mounts, these are perfect for stealth mounting extra drives, but also come in handy should you wish to completely remove the hard drive bays to make way for a huge water cooling system.

The top panel is removed with a single thumb screw at the back of the chassis, it features a dust filter that can be easily brushed clean. The top of the chassis features long screw holes for maximum compatibility with 2 x 120mm or 140mm fans, as well compatible water cooling blocks of up to 280mm.

With the front panel removed we can better see the two 120mm air intake fans, these are positioned perfectly to cool our HDD bays, but we can do a lot more here as you’re about to see.

Remove the fans and you can also remove the slide rails and panels for the storage bays, suddenly you have room for a massive water cooling radiator, reservoir or what ever else takes your fancy.

If that’s still not enough room for you, you can also remove the bottom two HDD bays and their caddy.

The hard drive bays features a tool free clip that extends the bay wider, it can then be clipped shut to hold the drive in place.
