Interior chassis of this case looks identical to the Aerocool ds cube that was featured before on Guru3D, 7 years ago: https://www.guru3d.com/news-story/aerocool-new-color-models-dead-silence-cube-series.html https://www.techpowerup.com/review/aerocool-ds-cube/images/caserear.jpg Only big difference that I can tell from specs is that the Chieftronic m2 doesn't have a front mounted 3.5 & 5.25 drive bays, and uses x2 120mm fans as intake instead of the 200mm on the Aerocool ds cube
