Vibrational/ acoustic properties of plexi?
I'm gearing up to craft a custom water cooled case, and am down to a few material choices. The easiest material to work with will be plexiglass, but I'm concerned about possible negative vibration properties. Does anyone have experience with the acoustic properties of plexi?

Awesome. I think I'll go for it, then. frosted plexi and burled walnut has a nice sound, no?MikeC wrote:It's good -- good internal self damping, with better sound blocking properties than the typical steel or aluminum case, maybe because it's always considerably thicker. The thickness probably plays a big part -- too thin and it might be resonant.
It's all going to depend on the T(g) of the resin used. In general, acrylics usually have a lower T(g) than polycarbonates (Plexi) and are softer (less brittle/stiff) and less likely to resonate. Acrylics also tend to be a little denser, which helps.
Mike's right though, if it performs better than steel, it's due to the added thickness.
