Background: Own a MacBook Pro 15" early 2011, had the logic board replaced for free when Apple was offering to replace them for flawed display issues earlier. It's failed again and won't boot, gives me similar display effects. My guess is logic board display is kaput again. I'd like to get a new MacBook Pro but given new ones are about to be released I don't want to go in for the plunge until they are released. That said I need a Mac to work on in the meantime. Planning to get a used mid-2012 MacBook Pro 15" -- why not later versions you may ask? I have a 1tb ssd I was using with the old early 2011 MacBook that works great. I want to continue to use it ideally (I have a time capsule backup for the Mac OS X partition but not the boot camp). And from what I know beyond the mid2012 connectors to the hard drive has changed, besides its costlier too. Any alternatives I may be missing? I could get a Mac mini but I'm not sure what the last model was that accepted a basic sata hdd. Also I need the same compute power as my old system which was a quad core 2.0 ghz. Thoughts? Suggestions?
