How strong is the Wii? (as in how easily will it break)

I'm just wondering, because I had bad luck with the 360, and I'm just wondering if the Nintendo Wii isn't easy to break like it's older relatives.

First, what is the strongest blow it can take without taking any damage?

Second, how loud is it, and does it make you nervous when you hear the noises within the system change?

Lastly, how can I take care of it besides not destroying it by accident?

Thanks in advance.

Well, I know a few who dropped their Wii and it broke. I suppose it just really depends from what height it dropped from and where hit got it. Just don't try testing it.:P
