The latest flagship of the prestigious Dark Base series by be quiet! in this respect, it is the quietest cabinet we have ever tested using the current measurement methodology. At the same time, it does not lose its primacy even after the alternative replacement of the full cover of the front panel with an open, freely passable grille.

The main motto of the manufacturer of the case tested today is “Outstanding versatility, performance and silence”. CEO Aaron Licht adds that the Dark Base Pro 901 is the culmination, where the performance and maximum versatility of the cabinet is underlined by new features that have not been seen in any other be quiet cabinet! used.

The manufacturer itself recommends the cabinet for high-end gaming and multimedia setups, powerful workstations, water-cooled and high-clocked setups, and last but not least, as a built-in solution in an inverted arrangement.
The highest model from the be quiet! surprisingly, he had to settle for a simple box made of natural cardboard with a single-color print, which apparently did not command the same respect from the carriers as the varnished cardboard with a full-color print previously used. Crumpled corners and deformations indicate that the 20 kg package was handled very carelessly.
Compared to the predecessor Pro 900, the box is relatively sparse on information, on its side we find at least a table with selected technical parameters and the necessary production labels.
The back wall then shows a drawing of the cabinet in its unfolded state with a legend and a few sentences about the manufacturer and the product. Those there are original photos of cabinet details with detailed labels.
The crushed edges of the polystyrene foam protective moldings are a bad business card for the multinational carrier that handled the transport from the manufacturer’s German headquarters. Fortunately, the cabinet surprisingly survived without visible damage. The protection of the glass side was strengthened by the inserted box with accessories.
What hasn’t changed from its predecessor is the use of a solid textile bag with the manufacturer’s colorful logo.
