So Im gonna start buying my Studio now that I got the cash but while looking for G4's...Ive spotted this powerbook. I am limited with SPace so what are the main limitations on a powerbook for a home studio compared to a tower. Im gonna be running cubase and this will be a dedicated computer only for recording. Ebay is the obvious choice to start looking but when spending over a thousand...Im kinda hesitant withem. Any good direct recommendations with specs and all of a typical G4 setup?
