The Sigma Luna brings many well implemented features, as well as a ready-to-go attitude, to the game. The black finish is perfect for the Luna, and is very easy on the eyes. It is extremely light-weight and well constructed. Installation was quick, painless, and enjoying. Many small details were not overlooked, which translates into fewer headaches. The case seems to be a well thought out and refined version of the reference design that was also used by NOX for their XTREME Moonlight. The Luna will certainly please those looking for an inexpensive and well built case, who do not need the size of a full tower case.
The main problem I had with the Luna was the installation of the hard drive. The Slidelock clamps are a wonderful idea, yet it was slightly difficult to get everything aligned properly, due to the line of sight. As I mentioned before, this could be easily fixed by making the hard drive cage removable.
Overall the Luna WB is a very good case, and a great addition to a very competitive field of cases at a similar price point.
