First off: I am in no way related or affiliated with this seller but I just submitted a best offer and was surprised it was automatically accepted for $70. There is $15 for shipping so I figured I'd share this with others wanting to upgrade to a 1TB drive for a decent price since these are $120 on ebay. This is a 12.5mm drive so I'm going to place this in the HDD slot and move my 500gb to the optical drive as I have the optibay coming and will do a RAID0 setup so I will no longer need external storage except for Time Machine backups.
