Geez, I was only offering a different view. No need to get personal or defensive.
I care a lot for silent systems. I always have been. I have spent lots of money and time to insulate all of my cases very thoroughly I have ever owned, just so I could still use powerful components without using liquid cooling. I have also always used magnet bearing fans since they were available, since conventional bearings are too loud and unreliable for my taste.
The fact of the matter is, that a normal ITX system with a thin cooler and a good quality, slow spinning fan on it, offers better cooling and is only audible when you put your ear very close to it. This case doesnt offer any advantage, instead its much more expensive than mentioned example and its a lot of work (and costly, if you use expensive thermal paste) to open and close again, if you just want to change or check something. There are MUCH better cases for half-height ITX boards out there, which actually are much smaller than said M350, and thus would at least offer one advantage.
