THE N4100EVO EXTERIOR

The N4100EVO is not a small NAS server (due to the 4 drive bays) since it measures 22mm in length, 192mm in height and 165mm in width but it's actually a tad smaller than the TS-4xx line of NAS servers by QNAP. 

However compared to 2 Bay solutions like the TS-269 Pro the N4100EVO is quite larger. 

Unlike units by QNAP and Synology we see that Thecus prefers a more industrial like design for theirs.

The N4100EVO has a total of 5 activity LEDs at the left of the front fascia (power On, HDD activity, Ethernet 1/2, system state). 

Beneath the LED readout area we see a USB 2.0 port, the power on/off button and the EVO logo.

You can use the 4 small buttons placed right beneath the small 2x16 LCD screen to check the state of the unit.

All of the 4 drive bays feature locks and are hidden behind a hard plastic door.

The drive trays themselves may not be of the best quality I’ve ever seen but they get mounted a lot easier than every other I’ve ever used to date and as expected Thecus has placed mounting holes at the bottom for both 2.5" and 3.5" drives.

The same industrial look extends at the rear of the device.

Here we see an 92mm exhaust fan manufactured by ADDA (can reach speeds of up to 2400RPM and produce up to 43.5CFM of airflow at 31.3dBA), an USB 2.0 port, two gigabit Ethernet ports, the AC power port and the 20mm exhaust fan of the built-in 150W PSU.

At the bottom of the unit we see 4 round rubber feet (which unfortunately black any white surface they come in contact with).
