While there are a few cosmetic differences, the TS-470 looks very similar to QNAP's other 4-bay NAS servers. Aside from the front panel, which is a mix of glossy and black plastic, the device is made almost entirely of metal. The TS-470 measures 177 x 180 x 235 mm (6.97 x7.09 x 9.25 in) and weighs in at 4.56 kg (10.05 lbs) without any hard drives installed.
Above the drive bays, you can see an LCD panel and a pair of buttons (Enter and Select). The panel and buttons can be used to view system information and perform an an initial disk configuration. Right below the LCD is a series of LED indicators used to show the current state of the system, network and any USB devices connected to the NAS. Also on the front is the TS-470's power button, one touch copy button and one of its many USB ports.
The rear of the TS-470 is pretty straight forward. Along with the power connector, there is a 9cm fan. This fan is temperature controlled and only spins as fast as needed to keep the system cool. To the right of the power connector, you can see the TS-470's expansion slot. The NAS comes with a dual-port gigabit PCI-E network card already installed in this slot. However, it can be swapped out for a dual-port 10GbE network card or an SAS dual-wide-port storage expansion card. Below the expansion slot, you can see the TS-470's audio and MIC ports, two eSATA ports, dual gigabit ethernet ports, two USB 3.0 ports, two USB 2.0 ports and a single HDMI port.
