    Good for my needs, might not be ideal for everyone

    The case is fairly easy to build in and the airflow works nicely. The front panel and side glass panel snap into place nicely, and the back is secured by some thumb screws that make it easy to access. It's a nice size for an mATX case; it's smaller than ATX cases, but it's not quite so small that you have to be choosy with parts and worry about managing cables. There's a box that has the accessories you need (motherboard screws, HDD/SSD screws, zipties), and the cable management is pretty good, although the mesh area on the bottom means you can see any cables that are in the PSU area. A couple points of concern: The case has an area that can house one 3.5" hard drive or two 2.5" storage drives. It also has an area that can house a 2.5" storage drive, but the drive MUST be installed before the motherboard is put into the case. The PSU fan MUST face upward into the case. Most cases allow you to install the PSU with the fan facing in or facing out (which is usually preferred), but this case has a solid bottom and won't even let you install the PSU the other way. I personally don't mind, since having it face up prevents any issues with carpet, but it's unusual so it's worth noting.

    A nicely designed and easy to work with mATX case

    There's plenty of space to work in, lots of precut slots make cable management easy, and it's very easy to clean out the mesh panels. I wish they sold a version with a metal side panel, but it's easy to cover up the tempered glass panel with a vinyl decal of your choice.

    Go To MATX

    Great MATX case. Full support for ATX power supplies made my case swap from a larger case a breeze. Support for 140mm fans is also a nice plus keeping noise and temps down.

    Great case for a micro atx build.

    This case was exactly what I was looking for when I needed a new case to make my old pc look better. Everything fit in perfect, it was pretty easy to build in, and it looks great. The only issue I have is that it is awkward to carry once you are done building as every panel is pretty flat. Won’t matter once you get it in place though. Overall a really nice case.
