Specifications and initial thoughts
With its curvaceous front and anodised black exterior it's a real looker, but at almost two feet in height and over two feet deep, the ATCS 840 is more likely to dominate rather than co-habit your desk.
Therefore unless you've got a gargantuan workspace, you'd be best to keep this chassis underneath, rather than on top of your desk.
Looking at the specs below, storage capacity is very generous and makes good use of the chassis' dimensions. It's unlikely even an enthusiast's needs would exceed the available 3.5in and 5.25in drive bays.
The standard fans in the chassis should, on paper at least, offer reasonable, if somewhat unbalanced, airflow.
