I need to replace my internal HDD on my mbp (late 2011, 13"), however the drive I would like to purchase does not appear to have a normal enclosure like the one that came with my macbook. Is this going to be a problem to install "as-is" in my macbook? I know that normally internal drives come with top casing that hides the internal components.
Seagate Momentus Thin 320 GB (7mm)
The HDD I can acquire and want to install
Seagate Momentus 320 GB (9.5mm)
The similar but slightly taller HDD model with the normal casing.
