Hey folks, I'm wanting to buy a used Mac Mini to replace a very old (and failing) PC desktop for my kids. They are young (6 & 8) and all they do on it is play browser-based games on kid sites. 1. I don't know the Mac Mini line, but am assuming the older generation would suffice and I could save money. Can you confirm this, and if so, is there a particular model (or serial) number I should look for or stay away from? 2. Can you recommend any quality online stores to buy from, or should I just go the ebay / individual user route? Thanks in advance.
