First, is there a thread showing or discussing this upgrade in this model set already? I see a lot of threads for the new models so I want to start a thread for the older ones. I'll do my best to keep this up to date and hopefully with a parts and step by step how-to. Replace the optical drive with an SSD: Option 1: OWC Data Doubler $79.99 Option 2: MCE Tech Optibay $99.00 + free SuperDrive enclosure (Mac Mini version) Option 3: Can you get away with not using a special holder? Sure could put that money toward a bigger ssd. If you have used either of these post the good or bad. If you have a 20" or 24" iMac and want to keep this thread around let me know.
