Welcome, Matthieu. You’re going to love your MPCNC!
I am a big fan of the universal mount you referenced. We had a discussion about it a few weeks ago here: https://www.vicious1.com/forum/topic/new-universal-mounting-system/. I have created a number of mounts already, including one for the DW660. See them here: http://www.thingiverse.com/thing:1245848. A couple of other folks here also have created mounts for it.
Looking forward to see what you do with your new machine!
