Excellent guide. My Microsoft Surface Pro 2 now sports a 240GB SSD and is running smoothly with openSUSE Tumbleweed (Linux) and life is good ! Thanks a bunch.
Oh and a tip… try to use the right screwdriver otherwise you might have to CAREFULLY use a vicegrip to rotate the screw out… NOT FUN and very SCARY (i.e. may junk your motherboard): TLDR: USE CORRECT SCREWDRIVER ALWAYS.
