mmmh, in reality, the other potential big issue is the EMI (Electro Magentic interference) noise.
It would be interest in cheking it out how much EMI garbage is being thrown out due to the lack of metal shielding

I'd also like to mention that the foot print on this thing is ridiculous. Most of us keep out towers under our desks and having a 15"x16" box under your desk isn't exactly handy. Plus, I have to look at all the dust on my machine, which will be alot worse because of the horizontal rather than vertical orientation of the mobo.
