I've got a 2011 Mac mini that I'm selling because I simply don't have a place for it. It's been lightly used on and off over the past couple years. No blemishes, and the RAM has been changed to 4GB (although it's 1066MHz instead of 1333MHz). I'd also be bundling it with an Apple Wireless Keyboard (A1314) that I got a few months before the Mac mini. The keyboard is in pristine condition (no scratches on the plastic underside). Looking around ebay's completed listings for it, I was thinking $500-550 would be a fair price. Any thoughts?
