Unicorn from Sigma is a steel mid-tower case with a dark transparent side window and four 5.25” bays, two external 3.5” bays, five internal 3.5” bays for hard disk drives (four available in a removable hard disk drive cage), four fans (two 80 mm and two 120 mm) and aluminum door. Let’s take an in-depth look at this new release from Sigma.

This case has a front door, but only its front-most part is made of aluminum, the back part is made of plastic. On top of this door you can find the two LED’s (power and HDD activity) and the two switches (power and reset).

In Figure 4, you can see the front panel from this case with its door opened. As you can see, it has four 5.25” bays, two external 3.5” bays and one 120 mm fan cooling down the hard disk drive cage.

The main problem with this case is that the audio and USB connectors can only be accessed when the case door is opened. If you have a headset with microphone to play online games with VoIP function or to talk on Skype, you will have to leave the case door permanently opened – or at least half-opened. This is simply ridiculous.

This case doesn’t have an eSATA port or a FireWire port, features easily found on competing cases. On the other hand the two USB ports available are located far away from each other, allowing you to use two “fat” USB devices (like pen drives) without one device blocking the installation of the other.

In Figure 5, you can see the rear panel from this case, which has a very traditional looks, with the power supply on the top, seven slots for daughterboards and one 120 mm fan.
