The geek version of the saying “You can never be too rich or too thin.”  is “You can never have too much RAM or harddrive space.”

MCE Technologies took half of this to heart and is now offering the MCE OptiBay Harddrive, a 500gb 2.5″ harddrive replacement for the optical drive of the 17″ MacBook Pro. This, along with another half-TB for the factory-installed harddrive of the lapzilla, you can conceivably have a full terabyte in there and fulfill your lifelong dream of keeping every single file you ever owned or made with you at all times.

Sure, like a MacBook Air, you’ll be optical drive-less, but heck, think of the bragging rights!

And if you’re worried about the displaced Apple-issued hardware, MCE thoughtfully includes external enclosures for both the optical and the hard drive. (For the US$799 tag, they’d better! Add US$149 for a quick MCE overnight install, or US$99 for more leisurely shipping back and forth.)
