I have an old Compaq Presario 1620 I got from my uncle (never turn down free stuff!) And it only has a 650MB HD.. maybe it was 1 GB, anyway I was lookign around and I foudn somethign that said because the provessor was 133MHz or slow 6GB was the max. I guess that doesn't bug me too much. But i wanted ot make sure, and also, does anyone know a good place to get a 6GB HD cheap?
