Product Showcase - Exterior

 
The looks are charming alright, the tempered glass gives it that amazing look and feel. The top side cover is kept in place with magnets, if you look closely at the bezel, there is spacing left in-between the edges for lots of airflow.
  

The 4000D provides plenty of space for radiators and can support many case fans. The chassis has a modest size of 453mm x 230mm x 466mm / 17.83" x 9.06" x 18.35" . Motherboard form factors supported are: E-ATX, ATX, microATX, Mini-ITX.

At the back side we see seven plus two expansion slots, dual-slot cards can be set up in Crossfire or SLI mode as well (albeit that went the way of the dodo), one card could be mounted vertically (you'd need a riser cable of course). All the way below we see the PSU section. PSU wise, you name it... it'll fit as we'll show you later on.

The chassis at default is fitted with two 120mm AirGuide fans designed with anti-vortex vanes that enhance cooling. A RapidRoute cable management system makes it effortless to route major cables through a single channel,
with 25mm of routing depth behind the motherboard.

At the top, the front panel connectivity can be found, including 1x USB 3.x, 1x USB 3.x Type C, power, reset, headphone/mic. and that's it.

You are looking at a solid Steel front panel with wide ventilation channels for plentiful airflow, and if you need more, opt the airflow version with a meshed front bezel.
