Good info. I am thinking of putting together an ITX gaming build based on the Z270 platform, using the Cooler Master Elite 130 case and utlising this handle in the optical drive bay to help move it around.
Its a shame its quite expensive (actually more expensive than the case I am planning on using for the build 
) but its definietly a quality item and very useful. I am quite surprised no one else is offering such a solution.
