I'm going to spend money on a new keyboard (got), two 500 GB WD Green HDs, a Rosewill two-in-one encloser, and a Rosewill 7 USB Hub (for the computer and backing up all my music).
My Music collection is not even 100 GB but I know it will slowly grow so 500 GB a pop is enough for it.
Or maybe save more money for a RS2i, mmmmmmmm.
