The ineo I-NA559N Pro
For the most part, everything on the outside of the ineo NA559N Pro is made of aluminum. The front even has aluminum buttons. Each drive has two LEDs dedicated to showing their activity and status. You can also lock each drive in place since each drive bay has a lock. At the bottom a display shows the status of the NAS. There are also a set of buttons that allow you to manage several aspects of the NAS.
I really have no idea why ineo would include an audio out and in on the front of the NAS. This system is based on the ION platform so the motherboard used will have these features, but it's not a feature used on NAS appliances.
The side of the unit uses the same thick aluminum as the front of the NAS, but there is a mesh area that allows air to circulate to the vital components.
The back is where things really get interesting. This is the first NAS that I know of to come with a HDMI output. You can add to that a DVI and optical out! You aren't going to need these, just plug in the power and the Ethernet and walk away.
Here is a closer look. I'm sure the modding community will have fun turning the ineo I-NA559N Pro into a full on PC.
The other side uses the same aluminum mesh to allow cool air to cool the system.
