Thinking about switching to a 2011 13". My current system is in my signature. Could I just take out my harddrive and stick it in the new system? Are there any issues with that? Also, will the 1tb harddrive fit in the system as it's a bit thicker than typical 2.5 harddrives. I know this was an issue a couple years back, just wanting to double check that it still allows for the slightly thicker drive. Thanks!
