I have the full size version of this board. If it is anything like mine, it has Costar stabilizers (this seems to be like garlic is to vampires to linear and tactile guys). They're rattly, but oh so consistent and smooth without any modification. Additionally, boards with exposed aluminum plates or casings tend to ping. It is no coincidence that I have put box navies into two such boards (a Corsair K65 and my Das Pro 4). They really bring out the full pingy potential of such boards. Your post made me look into the specific marketing of the board and found this humorous:
Maybe the bottom of the case is "resonance-free", somehow. That doesn't seem to help with ping since my Das pings about just as much as my K65.
I don't do that whole silencing thing, but some people stuff their cases with foam, neoprene, etc (I would imagine something static free would be best). There seem to be plenty of opinions on this if you look around.
As far as the switches go, I couldn't comment myself. I don't particularly like tactile switches and don't have any complete boards with Gateron browns in them. The few I have in a tester felt pretty normal to me for an MX clone.
