In the market for a Mac mini to replace my 2011 model that I was using as a media server. I found two on Craigslist that seems like they could be a good deal. Both are 2012 models with the 3.6Ghz i7 CPU. One has 16gb ram and a 1tb drive for $400. The other has 8gb ram and a 500gb fusion drive for $300. Is either of these an especially good deal? As a side note, I have a 256gb SSD I had planned on swapping in as a system drive.
