I've received no human response yet from BA to my support ticket requesting a PSU replacement for my failed unit.  It's been about 45 hours now.

Since the unit is offline anyway I thought I'd take it apart and see if I could find another way to get power into it.  No luck on that front yet, but I did find something else.

I saw that there are 10 decent-sized electrolytic caps on the backplane, and I scanned the tops of them out of habit for signs of bulging, and guess what...out of the 10 caps, 5 had bulging tops, 2 of them to the point where the electrolyte was leaking out.  That's after just 13 days of use.

They're labeled as Sanyo brand caps, rated for 16V 1500uf, 105c.

I guess I should think about ordering up some replacements.  I wonder what kind of shape those caps are in in the still-operating miner...
