If you have opened up your new mini did you damage it while making the upgrade? I'm trying to decide if it's worth the hassle to upgrade myself. I get the education price which already cuts the price by $150. I estimate that I would save another $150 by upgrading the base model, plus I would end up with a faster drive. How easy is it too damage the case with putty knife? I did upgrade my imac 2.4ghz to a larger hard drive. It was a bit stressful and I ended up breaking a plastic clip that holds the screen in place.
