Anyone here purchase any of the optibay alternatives? There's a seller that has NEW IBM Thinkpad Lenovo T400 SATA 2nd HDD Caddy DV13 that is under $12 shipped. Anyone know if that would fit the mid 2010 13" Macbook Pro? *added* Oh I tried adding my 12mm BD drive but didn't want to fit so I guess I need a 9mm optibay or similiar? I found this, 2nd HDD caddy Macbook pro OptiBay SuperDrive SATA 9.5mm.
