Too much empty space in my 2011 mac mini, so i filled it with a SSD
The repair went great, iFixit's instructions are easy to follow. however my SATA cable was faulty. but iFixit had a new one shipped out right away. their service was great. with the new cable the repair worked well.
Done be intimidated, the mac mini looks small and packed, but this repair is quite easy with the right tools, there are not too many screws to keep track of, just take your time and follow the instructions.
