Turns out my old PC had great timing for dying - there's an Intel CPU refresh due in a couple of weeks which will include mobo refreshes. Problem is I needed the new PC now :-( So the parts I wanted (and my alt parts if they were out of stock) were sold out everywhere I tried. Got a reasonable setup in the end though. And the Fractal Design S case is both a dream to work with and practically silent without really putting any effort into making it so.
