I've just unboxed my new PC ( http://www.pcspecialist.co.uk/spec/V...20XT-270FB/80/ ), removed the foam insert and connected the side fan's cable. it seemed to power up okay, and made a single beep but then my monitor stayed black and after a few minutes the PC switched itself off. I am not sure if this is anything to do with a mistake in connecting the fan cable (I attached it to a free opposite cable which was in an empty corner at the lower right of the case)
I'm a bit worried that something may have been dislodged in transit, as the foam didn't seem to have molded itself around the motherboard and fell out as soon as I opened the side panel. Nothing seems to be out of place at first glance, though.
