I am interested in purchasing the 13GNFU1AM030-1 HD Caddy.

My question is, how difficult is it to install one of these? I have installed RAM on notebooks, and that's about the extent of my hardware modifications.

Also, could anyone help me choose which HD I should purchase? I would like another with atleast 500gb to run Linux off of, instead of just have 2 different partitions.

Thanks a lot!
