UDOO HDD mount
This is my UDOO HDD mount. It consist of 2 parts, 1 for clipping the HDD and another to isolate the electronic from touching the HDD metal case (see picture).
Note that this is only for 2.5" HDD, NOT the 3.5"" PC HDD. There is air vent underneath, so it's very recommended to put rubber pad to leave space underneath, plus reduce the vibration of your HDD.
M3 bolts are used btw :)
