I'm looking at picking up a mac mini for basic computing; word processing, youtube, web browsing, etc. I will need to do some photo processing in Light Room, but I probably only do that 6-8 times a year, and don't do any gaming. Bleeding edge performance is obviously not required for my use case. I have my eyes set on the 2011 Mac mini with the 2.5 i5 processor and the Radeon GPU. I've focused on this model for the dedicated GPU, plus the ram and HDD can still be user upgraded, which I plan on throwing 16GB and a 256 SDD in there right away. These 2011 minis can be had for fairly cheap on eBay, which is nice too. I'd love to hear some of your experiences.
