Man, I love reading these Bose threads-- can't get enough of them.
But, I like to offer my thoughts.
1) So, you, us, we or I are in the know about Bose. We need to relax. Some people like, Bose sound, many don't. I truly understand why we want friends, relatives and others to get value and performance out of their audio products. But sometimes, you have to let sleeping dogs lie.
2) HTPCs. If you are so inclined, you can build one for yourself, and beat in quality what you would purchase from most anyone.

I would think a lot of noise issues could be mitigated by having a server PCs and optical out to your a/v receiver. I have a decent setup with a modded xbox, that can act as jukebox and my optical out goes into my a/v receiver. You can also stream video, audio, use Tivo-like program if your hook up a tuner card to your htpc and you are set. It's a fun, if sometimes daunting set up.
