question about noise levels (Score 2, Interesting)

I don't own an X-Box but had a loan of one a while back and from memory it was quite noisy. I don't want to watch my movies with a jet engine in the room. Does anyone have any feedback on what the noise levels are from this unit. I have done a lot of work getting my PC down so its near silent. Am I going to have embark on a similar project once I get my modded X-Box home?
