  • Rated 4 out of 5 stars

    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.
