It seems to me that the biggest issue is the case... I don't think such a small fan can make that much noise just by itself. I'm wondering if when it's opened, you get that much noise
 

Hi just bought a GuruPlug Server - PLUS.
After 2 months waiting for that plug computer to arrive, I finally start playing with it.
First disappointment came after about 2sec. That plug  computer have a fan and it makes more noise than any computer I have ever owned !
It's annoying to the point where I'm not 100% sure it's normal. Does anyone have a GuruPlug server plus and can confirm that it's unusable because of the noise ?
