Raidmax Sigma ATX Tower Chassis




The front of the Sigma offers quite a bit of styling, with the angular lines, sections of mesh, and large brushed aluminum insert. Not one angle used here are square to another, nor do any run on a level horizontal plane.





The top of the chassis mimics the styling on the front, but the aluminum and mesh inserts have swapped sides. Again, there are many angles and sections of plastic adding style to the design.




The left side of the chassis is entirely glass, tempered glass with a slight tint to it, to be exact. Thumbscrews hold the glass in place, as it aligns well with the plastic of the bezel and the top cover.




The back of the Sigma starts at the top with a thick plastic top cover that can be easily removed. Below the cover is the rear I/O area and the exhaust fan. Moving down a bit more we find the externally accessed expansion slots and the cover to the right blocks any passive ventilation. The large hole at the bottom, you guessed it, is for the PSU.




The right side of the chassis has little to offer outside of a huge expanse of textured black paint on a flat steel panel. We do see that it aligns well like the glass panel does to the plastic components, and this panel is held in place with a pair of thumbscrews.




Above the right side panel of the chassis, in the top cover, we finally get to see the front I/O panel. There are similarly sized buttons for the power and reset, and a tiny square hole where the HDD activity light glows from. Along the edge, we see the USB 3.0 ports and the 3.5mm jacks for HD Audio connectivity.




Under the chassis, we find rectangular legs with oval rubber feet on them, pushed very near the corners for stability sake. The PSU cover at the back is easily removed for cleaning, and we see screws which allow one part of the HDD cage to be removed, and also see grommets for mounting an HDD to the floor of this chassis. Also, notice the bottom of the bezel, it is shaped so that an LED light will show that in reverse on whatever the Sigma stands on.
