Cost-Effective Cooling
I was looking for a lower-volume case to replace my SFF case that wasn't cooling my hardware as well as I liked. The amount of airflow and cable management this case provides for mATX and ITX components was exactly what I was looking for. Despite the lower price, materials are of relative high quality. Easy tool-less panel access is perfect for upgrades and mods. Only things to note: remember to remove securing screws before attempting side panel removal and the wider footprint of the case caused by cable management channels. Phanteks did extremely well with this one.
