This may echo some of the other responses but,I am glad they don't offer more than a adequate powercord.
That give me the option to buy what I prefer. The debate about powercords can go on forever and a equipment manufacturer would be foolish to enter into that with a prejudice for one brand or another. I am not debating the effectiveness of aftermarket powercords, as I have on on 90% of my equipment. And I have a brand preference and would not like that idea that I paid an extra 200 or 500 dollars for a PC that I wouldn't use and couldn't sell. I could sell it because, I would need to keep it to maintain
all original equipmenty, packing and manuals for resale.
