http://www.macworld.com/article/152061/2010/06/macmini2010handson.html It seems much easier than the previous generation forsure! Perhaps the most frequent question I’ve heard since the mini’s release has been, “How difficult is it to replace the hard drive?” So far, the answer I’ve got is, “Much more difficult than replacing the RAM.” As you can see in the photo to the right, just being able to see the hard drive requires removing six screws, pulling the fan mechanism to the side, and removing the metal screen that holds the AirPort antenna. Once we get our own Mac mini (the model pictured here is on loan from Apple), we’ll explore a bit more, including covering the process of replacing the hard drive. On that note, Apple’s policy on upgrading the Mac mini yourself has always been that as long as you don’t break anything in the process, your warranty is still valid. I confirmed with Apple that this is, indeed, still the case with the newest Mac mini. However, the company contends that because the new mini includes at least 320GB of hard-drive space—and you can upgrade at the time of purchase to 500GB for $100—there’s less of a need to upgrade the hard drive than when the mini shipped with only 160GB.
