I recently ordered a refurb 2012 mac-mini i7 and would like to upgrade the RAM and install a SSD. I'm not entirely certain that I know what to order in advance of delivery to make the changes ASAP. The main issue is that some late 2012 mini's apparently have the hard drive in the upper slot. Do I need to order anything other than the following to be ready to go on day one? 16 gb Crucial RAM Crucial MX100 SSD OWC Data Doubler DIY Installation Kit Thanks in advance.
