Sigma Unicorn Case Review

Inside Unicorn

The way you open this case is different from all cases we reviewed so far. Instead of removing some screws or pressing a latch on the rear side of the case to remove its side panels, the side panels are removed by pulling a latch located on the top part of each panel, see Figures 6 and 7 to understand. You can remove both panels and the motherboard tray comes attached to the right panel. After the case is opened the side panels continue attached to the case.

The first thing you should notice is that the left side panel is dark transparent, not clear transparent as it usually happens with cases with a transparent side window. This panel comes with an 80 mm fan attached to it, which glows red when it is turned on. The left panel also has a side venting mesh, which is used by another 80 mm fan that is attached to the case on top of the daughterboards, helping dissipating the heat generated by the video cards. All fans from this case use a standard 4-pin peripheral connector, meaning that they don’t have speed control and you also can’t monitor their speed.

In Figure 9 you can have an overall look inside Unicorn. On the left side you can see the rear 120 mm fan and also the 80 mm fan on top of the place where the daughterboards will be located. Next to this fan you can see three plastic mechanisms to firmly hold daughterboards in place, in order to avoid them from getting out from their slots when you transport your computer, which is very common to happen especially with long and heavy video cards.
