Do you guys think that a BTO has a lower chance of a yellow screen? It seems that every report I've read about seems to be in a stock configurations (mostly 21.5"). Maybe the stock configurations do not have as much QA testing since they just roll off the assembly line, but the BTO actually requires more attention to detail. I may be totally off base, but it's just a thought. (Hoping I'm right, since I have a 21.5" BTO on the way to me now).
