Solidly Built

This is a great compact case. It is exceptionally well built for the price. Ventilation could be better. I cut a hole in the top to mount a 120 mm fan that blows onto the CPU heatsink. Had to sacrifice the HDD mounts for that, but I didn't need those mounts anyway.
Sturdy, high quality case, airflow is another story

Using this for a pfsense build. Airflow is non-existent. The top cover could have been perforated and it would be okay. The front exhaust 80mm fan (they recommend you to use a slim version at 15mm) is almost completely blocked by the front design. The inlet 60mm fan would be blocked by the PCI riser card. I find these design choices very confusing. Fix these issues and this would be a totally 5 star case. It's one of the few on the market that's mini-itx and has an expansion slot! But such a bummer it has airflow issues.
