My wife's brother bought a Mac Mini Server but can't figure out how to use it. He wants to sell it but I don't know if it is worth buying or not, as I have a 2009 iMac and a 2010 Macbook. It is a 2010 2.66 GHz Intel Core 2 Duo 8 GB 1067 MHz DDR3 NVIDIA GeForce 320M 256 Mb OS X 10.8 1TB Would it be a lot slower than my 3.06 GHz Intel Core 2 iMac with 16 GB of ram? He only wants $300 US for it. Which seems cheap but I can't find how much one of those would sell for in stores. Thanks for any advice.
