Just a small note to all of you modding your units. I had 6 of mine not working and it seems they were not working because the screws were too tight and some solders snapped off. So be VERY careful when you put your pods back together! Right now, from 30 modded units it seems I only ended up with 1 paperweight (seems like one pod is too damaged 
) with the other 5 being recovered, which is good enough for me 
) with the other 5 being recovered, which is good enough for me I had noticed this as well with mine. I had thought it was just mine, but apparently not. I noticed these are VERY temperamental with regard to how tightly they are put back together. Mine also seems picky on how even the tightness is. The tighter the heatsink was clamped, it seemed the more hw errors I would get and it was more unstable.
Have you tried re-doing the solder connections to see if that helps the one pod?
