I was having lots of PSU problems recently, and it wasn't until tonight that I remembered about the Foxlink problems...
My box has been "arching" all summer, and only works when plugged in with the cord tucked under the box at just the right angle (I was using it as a fileserver, and on occasion had to turn it on).
Anyways, my bro was asking me (read:bugging me) to fix it, and I remembered I had a v1.1 box, with the Foxling thing, and I vaguely remembered reading something on here saying that the power cord replacements were useless because the PSU was the problem.
So, I opened the box, took out the PSU, and sure enough there was a gaping hole in the solder joint, and black burns on the surface of the board around the affected power input pin.
