I ordered mine as soon as they were released so I probably have one of the earliest ones they made, coconut identity further identifies as mine being assembled between 20-27 oct. if memory serves right. I've had absolutely no problems at all. It doesnt get hot at all and runs dead silent on top of being extremely fast. The only issue I've witnessed so far is that wireless reception is CRAP in Windows and I cannot use Coconutwifi anymore without the wireless getting screwed over. However the wireless signal strength doesnt randomly drop, if you leave it alone it stays constant. It does however fluctuate a lot in Windows. Could be a faulty wireless card, could be the new n-compatible cards they put in. It doesn't seem to affect Internet speed at all so I just kinda ignore it.
