The HS-210 NAS has quite a modern look and the top side of the unit acts like a heatsink, to dissipate the heat from the drives but also from the internal processor:
The frontal cover is removable and comes with the QNAP logo and product branding:
The NAS sides are made from the same plastic shiny material, with no additional ventilation holes:
In the back side of the NAS we have the DC-IN port, one small Reset button hole, a SD Card reader, two USB 2.0 ports, one LAN port, two additional USB 3.0 ports but also one Power button:
