My wife is not happy with her Mac Mini I got off eBay, it is the one in the thread. It is constantly stalling and beach balling and I already did a clean install of Lion from USB thumb drive. Not sure where the issue is and I have not been happy we are stuck with Lion on it so I am looking at eBay for a newer model. I am looking at a 2009 that can take up to El Capitan (will just go up to Mavericks though) and I found one that is going for a decent price right now but the SuperDrive isn't functioning. If I bought this could I just take the SuperDrive out of the 2007 and install it in the 2009 or are they different?
