Steel cases are usually cheap and very bad quality, aluminium cases are usually expensive and good quality.
I know which one I choose for my desktop.
Why don't you then start listing steel cases which use thicker than 1mm sheet?In 90% cases steel cases are thicker
While steel weights thrice the alu it's still not good in stopping vibration because thin metal sheet is thin metal sheet regardless of what it's made of and as non-elastic material steel conducts vibration quite well.Aluminium tends to resonate a lot easier then steel.

I haven't yet seen any advertisings, specs or anything about steel case which would use thicker material no matter how many times I've asked.

Giving real vibration stopping ability with layer of vibration absorpting material or through extra rigidity makes it heavy with all capitals. (Antec P18x/19x already use alu-plastic-alu layer structure to keep weight of side panels reasonable)
If weight is an issue and budget isn't so limiting alu+bitumen gives lot better vibration resistance per weight.
. And I think it's common knowledge too that thicker steel panels are better at drowning out noise. Of course it will depend on how the case is constructed as to whether steel or aluminium panels stop vibration effectively - because your right, a metal sheet regardless of construction and thickness can very often do nothing to help with vibration. I had an 800D whose sidepanel resonated a lot and that was a steel panel. I had a high end Lian Li that had no problems at all. But by and large lots of people have posted on these forums about how thin alum panels resonate. It's all over the place on SPCR about this. Steel panels don't tend to resonate as easily (which doesn't mean they never resonate), and have the advantage of being thicker. That's why some people prefer them. That's my experience and a lot of other peoples. So all I'm really saying is that a steel panel usually drowns out noise better because it's thicker, and from the cases I've tried - steel panels seem to be less prone to vibration. Yes, alum+bitumen can solve resonance issues but that's not what this thread is about. It's about alumin v steel cases not modding your aluminium panel with bitument or some other sound deadening tat.
