I would like to upgrade my late model 2012 Apple Mac mini to a 128 GB solid-state drive as well as a 1 TB hard drive. Will Apple Store do this for me if I pay them, if so how much? Or my better off going to an independent shop to have it done? I have apple care and don't want to void it, but I'm looking for better response time and more storage out of the Mac Mini. Also, if I upgrade the RAM myself, do I void any warranty with the Apple Care?
