Considering the cost of the 450 AP or SM, I don't see how you're so relaxed about that, compared to the quality control on a $120 ATX motherboard, which is a significantly more complicated PCB than any 450... I know I've never unboxed one and had pieces rattling around even on the very cheapest. On May 16, 2016 8:08 PM, "George Skorup" <[email protected]> wrote:
