I'm thinking of stepping out of my MacBook Pro 13" stream, and moving into a Mac Mini. I have a 2009 MBP and it's starting to slow a bit. I could pass this on to my kids, and upgrade. I do photo processing, working with Lightroom and RAW. Those are my heaviest tasks. I think any modern i5 mini would be an improvement (I'd add a nice 24"+ SIPS monitor But I was thinking -- what about the quad servers? I see some used Quad i7s for around $850. I have to imagine those boxes will be solid for several years, though I could save some money by just going with a dual i5. Are the minis, like the MBP, no longer user-serviceable? Can't change HDD or add memory? If so, what was the last year of the mini where you could update it yourself?
