THE ICY BOX IB-RD2121STS
The lower section of the ICY BOX IB-RD2121StS is made by hard plastic while the top is a thin aluminum plate.
Size wise the unit is identical to a 3.5" hard disk drive but needless to say it is a lot lighter (at least without drives inside).
The front bay door unlocks just by pushing the button placed at the left which i have to say doesn't feel very sturdy.
To mount the two 2.5" drives inside the enclosure you just have to slide them inwards and close the door.
At the rear we see the SATA data and power connectors, activity LED and the mode switch.
Most of the bottom surface is perforated so that hot air can escape the enclosure with ease.
