This case allowed me to connect an IDE drive 3.5 "SATA drive and a 2.5 'and 3.5' I could even connect an old internal DVD writer 3.5 "on the IDE ribbon cable, in this case I could not put the lid of the box but I could be my external drive for my EeePC, which I was able to repair XP and install ubuntu I had on a CD. In short, a very versatile product with room for fingers to easily connect the IDE and SATA.
