Space is tight at the compound (2 br apt). Time to downgrade to a notebook. I've been spoiled by SSDs but I need more space than that. How can I figure out which notebooks will allow me to install a second drive? I'm willing to remove the dvd drive and go with an esata optical drive if that makes sense, but it's really hard to figure out which models will allow this. So far I've figured out that the Dell XPS/Alienware 17 will let me do this.
