Powered by a dedicated and efficient platform from Intel, the J1900 quad-core processor and paired with 2GB of RAM, the TS-453mini is running the last version of the fully-fledged QTS which is currently at its 4.1.4 version and is also sporting a unique-shaped chassis design. Speaking about the chassis, now it looks more stylish, ideal to be installed in our living-room and the discrete LEDs help us find out the system status at all times; the memory is now very easy upgradable up to 8GB of RAM by simply removing a small plastic cover on the bottom area of the unit.
