Conclusions

Hardware Secrets Silver AwardSigma Unicorn is a very good case, with a sturdy construction and no sharp edges where you could cut your hands and fingers while building your PC. It provides a different opening mechanism and a removable motherboard tray, which always facilitate the computer building process.

It has also a very good number of hard disk drive bays – six or seven, if you don’t use a floppy disk drive –, which is a point we always criticize in high-end cases; some cases cost the double of Sigma Unicorn and still have only one HDD cage supporting only four drives.

Its screwless installation mechanisms are really screwless. Some more expensive cases still require you to use screws to attach rails to the hard disk drives or to the optical drives, which isn’t the case with Unicorn. There is one exception, though. If you decide to install hard disk drives to the external 3 ½” bays you will need to use regular screws to fasten the drives, as the mechanism available on these two bays are only compatible with floppy disk drives.

The only problem we see with this case is its price because at Newegg.com you can find NZXT Tempest costing the same thing (after a $10 mail-in rebate), and this case from NZXT is, in our opinion, a better product, and that is why we are giving Sigma Unicorn our “Silver Award” and not our “Golden Award”.

This case isn’t perfect, but for its price range we can’t complain very much about them. If you are a picky user, however, maybe these flaws will disturb you and make you to decide buying a different product. Since Sigma Unicorn is in the same price range as NZXT Tempest, we also included a small comparison between the two on the list below.

  • Its front door isn’t 100% made of aluminum; half of it is made of plastic. NZXT Tempest doesn’t have a front door.
  • The audio and USB front connectors are located on the case front panel, behind the front door. If you install devices on these connectors you can’t close the door. This problem doesn’t happen with Tempest as it doesn’t have a door.
  • It doesn’t have an eSATA port. Tempest has.
  • It doesn’t have a Firewire port, and Tempest also doesn’t have one.
  • No screwless mechanism for fastening daughter boards to the case. Same thing with Tempest.
  • Less fans than NZXT Tempest. Unicorn has two 80-mm fans and two 120-mm fans. Tempest has four 120-mm fans and two 140-mm fans.
  • Fans use regular 4-pin peripheral connectors, not allowing you to control or monitor their speed. The fans that come with Tempest use a motherboard 3-pin connector, allowing you to monitor their speed.
  • Unicorn can hold up to ATX motherboards. Tempest allows the installation of bigger extended ATX motherboards.
  • NZXT Tempest allows you to install radiators from water cooling solutions that are based on two 120-mm fans inside the case. Sigma Unicorn doesn’t.
