Used in a DELL Alienware X51, the accessory is perfect. Easy mounting of the SSD on the support, the support on the drawer, and perfect alignment of the connectors. Construction household cooling the SSD ... and housing in general.
The price is rather high, but once swallowed addition, we can only welcome this purchase.
The more complicated is to open the Alienware and access to its components, it is almost like an oyster.
