got my A71a today great case, no vibration noises,i did get a small cut on my hand somehow but that was probably from my old case and its more like a scatch that i didnt notice until after.
stock fans are very quiet the loudest fan in my pc is on my gpu

, i had to put my hands near all the fans to check they were spinning properly there that quiet, i didnt even realise in my old case but it sounds like the bearing in my gpu fan is going it rattles a bit on startup.
even when i first booted with the side panels still off incase i ran into any problems i could feel the cool air from the fans its amazing how quiet they are, during my research i came across people saying they swapped the stock fans out because they were to noisy but im thinking of getting some higher rpm fans.
i forgot to check what fans they were but connected by the 3pin my motherboard was showing them as 1320RPM.
the motherboard tray is slightly different than all of the pictures i saw during my research i guess they must have made a through revisions to the case at some point as my tray has a bunch of holes cut into it for cable management.
the only annoying aspect of the case imo is how you have to remove 4 small screws to remove the front panel in order to reach the dust filters other than that its perfect for me!
btw i can hear the rain outside hitting on my window ! i havent heard that in this room for such along time! i think i might have to get a quiet keyboard aswell it seems so noisy now! lol
