LOL, cool review. It sounds powerful indeed! I keep my windows tower under a table next to me, so aesthetics don't matter much in my view.
I do have a question on the price, $5-16K: Are the parts you listed the high or low end, and if low, WHAT amazing hyperdrive kind of stuff is in the $15k ones? I'm not complaining about price, just wondering what more could be added to, well, add up to that.
