To those who are upgrading their mac mini's hard drive. I was a bit unhappy to see that apple used so much EMI gaskets in the 2012 mac mini compared to the 2011 mac mini. I am pretty sure it is the same chassis, but I had a really difficult time trying to pull out the PCB portion of the computer. I noticed that there are many gaskets where there never was and I understand to be given FCC class B device, but it's like Apple just slapped on some gaskets, which is unlike the way apple designs things. I guess this is a cost savings move since they are using an "old" chassis. So for those who are upgrading, some things require more force than before to remove them because of the gaskets that did not exist on the 2011 models. Guess the new processors and chipsets give off more EMI.
