The N4350 is a very compact tower design measuring just 217 x 170 x 135mm with the four drive bays vertically mounted and hats off to Thecus the bays for installing proper locks on them which is a nice feature on a NAS at this price point.
To the right of the drive bays are a vertically stacked line of indicator LEDs. From the top these are for Power, four drive activity indicators, LAN, USB and system status. When everything is ok with the unit these all glow blue. Directly under these LEDs is the USB copy button with the power button sitting under it.
While the USB copy button is on the front bezel there is no accompanying USB port on the bezel, instead both USB 3.0 ports are built into the rear panel. While this is a bit of a pain, and to be fair to Thecus there isn't much in the way of spare space on the front bezel for the port anyway and the unit is so small, it's easy to get to the back panel although if it's sitting on a shelf you still might end up cursing about port access.
The rear panel of the N4350 is dominated by the grill for the 92mm (ADDA09212UB257B00) cooling fan. To the left of the grill are all the ports that the N4350 supports; a pair of USB3.0 ports, single Gigabit Ethernet and the reset button.
The drive trays are made of plastic including the doors. Unfortunately the trays are not tool free so 3.5in drives have to be fixed in place with screws (which Thecus supply) through the tray sides. The trays also support 2.5in (HDD) drives which are fixed in place through holes in the base of the tray.
