I found two new 2011-2012 Mac Minis. The general specs are the same (2.5GHz Core i5/4GB/500GB) but one is a late-2012 MD387J/A for 87,500 yen. The other is a mid-2011 MC816J/A for 74,500 yen. The reason I ask is because the mid-2011 MC816J/A has an AMD Radeon HD 6630M graphics processor with dedicated 256 MB of GDDR5 memory, while the MD387J/A has an Intel HD Graphics 4000. Also the MC816J/A is titled 'NO ODD MC816J/A'. What does that 'NO ODD' mean?
