Sigma’s Atlantis: A Solid Case for a Solid Case

Overall Score
Sigma Atlantis


Shortly before the holiday season XtremeCPU received a nice present from Sigma, a sleek case with a request to look it over and publish what we thought. So today we will show you a case from a vendor that is stylish and straight forward. As with any case, the design and aesthetics are a personal choice since cases are really meant for one purpose – to hold all the components that make the gear work. Such is the case the primary pre-requisite for any good case is that it provides sufficient cooling mechanism to keep the computer working properly. So long as the case meets this criteria, the other details become more or less one of preference.
The Sigma Atlantis case can best be described as a no-frills, solid case. In that, as we shall see, the case offers up all the necessary needs to be met by any case. The strength in this case is not in the functionality but the quality of the build. So as we proceed, take careful note of the information and pictures presented, at every turn the word the keeps floating into ones mind is ‘solid’.

As is often the case many people begin looking by consider the specs, for the sigma design you will find

  • Case: ATX mid tower, can accept ATX, flex ATX, micro ATX and mini ATX
  • Material: Solid aluminum frame and skins
  • Fans: 1 x 120 mm Front, 1 x 120 mm Back, and 2 x 120 Side
  • Drive Bays: 4 x 5.25” external, 4 x 3.5” internal, and 2 x 3.5” external
  • IO connectivity: 2 x USB, 1 Mic, 1 Headphone, and 1 1394E Firewire port on front panel.
  • Standard on/off switch, reset switch, and power/HDD LEDs
  • Blue LED Fan
  • Power supply (optional, reviewed without PSU)
  • Three colors: Silver, Blue, and Black available.

So overall a straight forward case with plenty of bay expansion, 4 fans of cooling, standard IO all encompassed inside 12 pounds of aluminum (a very light case indeed).

Accessories packaged with the Atlantis is as straight forward as the specs, mounting screws for drives and bay related hardware, stand-offs for MB mounting, and screws for the standoffs to hold the MB. It would be nice if a few more screws and stand-offs of each type were included in the kit, just in case one is lost or threads are gunged up during installation.
The manual included is well written but for all practicality not necessary. One should make a quick point concerning the stand-offs. The design of the case uses slightly different stand-offs than what is common in many other cases. Though not exclusive to the Atlantis (nor Sigma for that matter), take care to ensure you do not mix and match. Utilizing the incorrect stand-off, say from spare parts of prior builds, will offset the MB into the wrong spot.
