THE SILENTNAS HS-251 EXTERIOR
As you all know the HS-251 looks identical to the HS-210 and so once again we see the same flat design enclosure which measurements of 302mm in length, 220mm in width and 43,1mm height and weighs 1.56kg.
Just like with the HS-210 the QNAP logo and model name can be found on the right end of the fascia and at the top.
The fascia is easily removed to reveal the two inverted drive trays.
These trays are made out of aluminum and can accommodate both 2.5" and 3.5" drives.
Turning the device around we see the DC power in, reset button, two USB 2.0 ports, two Gigabit Ethernet Ports, Kensington lock, two HDMI 1.4a ports, two USB 3.0 ports and the power on/off button.
As mentioned in the intro page one of the HDMI ports is reserved for QNAP technicians who may need to service the device if something goes wrong.
The enclosure sits on 4 round rubber feet and is held together via 6 screws again found at the base.
