The Sigma is a chassis we did not expect to see. By this, we simply mean that we expected an aesthetically pleasing chassis, but we did not expect to like it as much as we do. The outside is a harmonious blend of brushed aluminum, steel mesh, and uniquely shaped plastic frames for the top and front of the chassis. The tempered glass side panel is another thing which helps the Sigma out, not only bringing up the cool factor but offering a view into the tidy interior. We also like the way that the LED fan lights up the bulk of the main compartment, the LED backlit Raidmax plaque on the PSU cover, and we were even fond of the Enermax name and pattern displayed just under the front bezel. The low amount of noise associated with this chassis is also huge, and there is plenty of room to expand upon the cooling in any way you see fit. The single fan does not sufficiently cool the chassis in our opinion, but many users will opt for an AIO to go in the front or up top, which will bolster the cooling capabilities of the Sigma.
The interior is well thought out, and we love that the dust filters are easily removable. Wire management is easily handled, not just with the access holes around the motherboard, but with a plethora of tie points and the near dozen zip-ties that shipped in the box. We found no issues when it came to mounting the components either. Everything either snapped right into place or can be screwed in with little effort, easing the entire build process as much as possible. While we usually have something bad to say with all of the good, in the instance of the Sigma, we cannot come up with a single thing that sticks out and is worth mentioning to try to sway you away from this case.
The Raidmax Sigma ATX Tower Chassis is worth the investment in our minds. At $79.99, whether you want it in black or white, leaves you with a bit of money left in your pocket to go to other things. The feature set is well-rounded, the layout and aesthetics are on point, and there is even a bit of modularity of you do not have a need for 3.5" drive locations. Everything about the Sigma well thought out, and seemingly no stone was left unturned. In our humble opinion, it seems that Raidmax is trying hard, and they should be on your radar when it comes to your next chassis purchase.
