That is a horrible deal. Refurbished 2011 2.5 GHz i5 Mac Minis run for 699. And 2010 mini can be had for 500 on ebay for example.
Well, I'm not doing price shopping. Apple refurb store doesn't have any of the appropriate models I was looking for. That vintage Mac Mini would seem to fit the needs for the cheapest cost and without sacrificing much/any performance for what its going to be used for. If you can find it on e-bay for $100+ less, great.
