First of all. This is not for newbies. Have you not opened and put together a computer before, I would say this is not for you. Call a friend though! ;)
One does not have to be a professional but pretty experienced, there are simple step by step instructions (with photos) on how to disassemble your Mac Mini, install it and – YES – the instructions take you step by step on putting it BACK TOGETHER as well. That is unusual, so this is a great feature by OWC. However there are steps that might need a bit of twerking, creative thinking and lots and lots of patience.
You will need to take the Mac Mini apart to the last piece. Which is so much fun! :)
This product is just great. Who would have known Apple actually designed the Mac Mini to fit two drives in the first place. All you need is the extra cable (included), tools (included) and some rubber and screws (included). And the drive of course.
I took an extra step: MOVED the original spinning drive to the second place, and installed a NEW SSD as the first disk. I think OWC should have this in their instructions as an extra optional sidestep. And there are some small steps that could have more detailed images and tips. Perhaps it comes in an updated manual :)
For Swedes: NO moms or taxes was added on my import :)
