M11x R3 Teardown video
As you can see in the video, it's not too hard to access to every single part of this little monster. An SSD update can be easily done with only a few scerws removal. Also if you use this laptop in intense gamming sessions, you shouldn't forget to do a proper maintenance. The fan and heatpipe can be accesed like the video shows and don't forget that a thermal repaste every year will extend your m11x life considerably.
