Hi Alexandre, I actually have been searching for this information a couple of times in the ML now. Was hoping that you would’ve been done with it before I ordered :) I will most likely order this week so I will see it when the stuff is being assembled :o Do you feel that there something in the setup that could be better if you would decide on hardware as of today? Also, will you try out replication set of 2 as well?
