I think the point here is that we know spending a months salary or 
more will get us a superior system, which is obviously what you've
done, unless you have more creative ways of obtaining your hardware,
but myself and others believe we are just building a fancy VCR, and we
actually enjoy pushing the envelope of our older unused hardware, 
and we simply enjoy the challenge. It's fun to find out how far some old 
motherboard can go and what we can do for cheap. I'm much more
impressed by someone who can get MythTV up and running on some
old junk than by those that do it the "proper" way.
