I have a different theory. Audiophiles are picky about their gear and if a company provides a $500 power cable that is a brand/model they don't like, it won't be used. And who wants to pay extra for a $500 cable they won't use? Better to discount the product, include a cheap power cable just in case, and let the consumer buy what they want. It makes the item look cheaper to the consumer and lets the consumer mix and match to their heart's content.
BTW, I formed this theory after Cavalli didn't include a cheap power cable with the Liquid Carbon. The theory was that audiophiles wouldn't use it anyways and it kept the price down. There was a lot of talk about power cables after that and some people did testing with expensive cables, as stated earlier, and found that audiophile cables did indeed make a difference.
Economy and flexibility are good reasons to omit uber pc's. I encourage it (getting whatever pc you can afford and like).
