Introduction

We would like to extend a big thanks to Sigma for supplying the review sample.

Here is what Sigma has to say about themselves according to their website:

Sigma is a manufacturer of power supplies and computer cases, both geared toward the enthusiast community. Sigma's product line promises stylish designs and a broad array of features, while keeping the costs to consumers low and the quality high. Today we have the opportunity to review their Luna WB mid-tower case and see if it lives up to their promise. The Luna is offered in two colors, black and silver. We will be reviewing the black variant. Another special note to take into consideration is that this case is very similar in design to the XTREME Moonlight made by NOX. It seems that the two cases have the same reference design.

Packaging & Contents

When the case arrived at my doorstep, I greeted it with a great big hug. I did this mostly because the cardboard box that it was shipped in was fairly large. Thankfully, the package itself was pretty light. Upon shredding through the big brown box, I discovered yet another box. This one, however, beamed at me with a certain feeling of elegance. On the front, we find a picture of the case and the word "Luna" underneath it. The ends are nearly identical, showing pictures of the two colors offered for the Luna series, as well as a few basic specifications. The only difference was a stamp with the words "No Power" indicating that this model does not include a power supply. On the back, we find more color pictures of the various features that are promoted for the case. Let us rip this box wide open!


I was really worried about the case when I removed it from the box, because it was very, very light. The first word that came to my mind was flimsy. My fears were later put to rest, because the case is quite sturdy. We will get into that later in the review. It was nice to see that the case was well-packed in thick styrofoam, and covered in protective plastic. They served their purpose very well, and there were no scratches or any other apparent damage during shipping. While removing the plastic from the side panel window, I observed that it was rather sticky. Initially, I was worried that the light adhesive would leave marks or residue. However, this was not an issue. The protective plastic came off surprisingly clean.


Inside the case, we find a four-page manual that details installation procedures for drives, add-on cards, and front panel leads. Also included was a white box that contained two small bags of various screws, stand-offs, and washers. Are you ready to take a closer look?

A Closer Look

Immediately, I am thoroughly impressed by the finish. The side panel window is large, and is accented with silver triangular highlights that help support it. On the underside of the case, we find four plastic case feet already installed. Also visible, is the chrome base for the front panel door, along with a vent to allow for the airflow through the front of the case. On the front of the case we see a sleek looking door, with a very nice finish. It has a single LED for power indication, and a silver strip that is attractive accent. The other side of the case has the same brushed finish.


The back of the case sports a standard ATX layout, with everything you would expect from the power supply down to the expansion slots. There is a honeycomb grill for the 120mm fan to vent exhaust air through the rear of the case. Next to the expansion slots, we can take a peek at the tool-free locking mechanisms for add-on card installation. Even included are four thumbscrews for quick side panel removal. Also visible, are the handles that are installed onto both side panels. We will discuss these next.


The handles that I mentioned earlier are another simple, yet effective approach to streamline installations and removals. Sigma was using their heads on this one, and the fact that the handles are hinged proves this point. They can swing inward, concealing themselves. In the pictures above, you will see the that the triangles on the side panel are blue. Or are they? That was actually a protective film, similar to the film you find on ramsinks. Thank the maker, as I feel that the silver is much more appropriate for this case. The vent for the 80mm intake fan is surrounded by a black plastic ring and a mesh grill, and is positioned to blow fresh air toward the CPU and PWM area of a motherboard.


Now we will take a look behind the front door, because this is one area where the Luna really shines. The door swings opens just over ninety degrees, so there should not be any clearance issues with optical drives. The front is made of plastic and has an extremely glossy paint job. There are twelve vent holes that allow airflow through the front of the case, also adding to the Luna's overall sleek look. In between those vents, are a power button, another power LED, a hard drive activity LED, and the reset button. Notice how they have the same finish, as to give them a hidden look. It all blends together nicely. Located at the bottom, are the two front audio ports and USB ports. This could be a slight inconvenience for some, because access to them means keeping the door open.


On the upper left corner of the door, you will see a small rubber strip that keeps the door from scratching the front panel when the door is closed. There is a rubber strip located on the bottom left corner of the door as well. Here you can also see the power LED. I think that Sigma did a nice job of keeping things tidy in regards to hiding the lead wire. Also highlighted are a couple of blemishes that most likely occurred in the factory. Since they are located on the inside of the door, they do not detract from the overall look of the case.


Moving across the top of the door, again we see the chrome trim. In the first picture you can see just how shiny the finish is, looking at the reflection of a thumbscrew. Located in the side panel window is the 80mm blue LED fan that has a Sigma sticker on it. In case you were wondering, I thought I would show you how the window is fastened to the side panel. The triangular accents fit through the panel and window, with a plastic washer and screw fastening them together. Let us now take a look at the interior of the case.
