The Unicorn comes with fitted Styrofoam and a plastic bag for protection during shipping. Not only is there a sticky plastic sheet attached to the outside of the window, but also on the inside, ensuring a scratch-free side panel. Other than the extra protective sheet, this is quite standard packaging for a case.
The front door is mostly constructed of plastic, but has a brushed metal piece in the center and chromed upper and lower pieces. This brushed metal finishing gives the whole case a very sleek, stylized look. On the right side of the door, there are meshed openings to allow airflow to the front intake fan. Opening the door to the right, we find four external 5.25” bays, two external 3.5” bays, a 120mm red LED intake fan, and IO ports. There are two USB ports and headset ports. Curiously absent here is any sign of Firewire or eSATA. Although there is a nice mesh grill for the fan, it otherwise has no included filter.
From the top of the case, we get a better idea for the construction of the front door. You can also see the power and reset buttons, as well as the power and HDD indicator LEDs. Sigma included hard feet with the case, which will not help too much in silencing fan or HDD vibrations.
One unique design point of the Unicorn is its tinted side-panel window. This smoked effect continues the classy theme introduced by the brushed metal front door. The left panel comes with two 80mm fans included, each tucked behind a restrictive grill. The fan on the support beam is a standard intake fan, and the fan above the CPU is a red LED exhaust fan. At the top of both side-panels, we find the handle for opening the side-panels by swinging them down in a butterfly fashion. On the right side of the case, we find the option for another 80mm fan, though it is not included. Removing the right side-panel also removes the motherboard tray. The back of the case is very standard. The line separating the left side-panel from the main construction of the case is visible. There is a honeycomb grill on the exhaust fan, and Sigma included an old-fashioned IO plate.
Now that we've had a look at the outside of the Unicorn, let's dissect this elusive monster.
