Kind of an obvious hack, but if you can live life without your Apple laptop's internal optical drive on the day to day, Macenstein demonstrates using an MCE OptiBay add-on kit to pull the optical drive out of your machine and swap it out for another hard drive. The hundies invested open such possibilities as software RAID 0/1, a dedicated Windows drive, or simply extra internal storage -- but almost all of the above will take another hit on your battery, so be forewarned before you dare to crack open that fortress-like aluminum case.
