Have a Optiplex SFF Desktop here with a single visibly blown Ruby on it. Just aft of the processor heatsink output, of course. PC won't POST, just sits at an amber power light.
The 520's appear to have the same capacitor compliment as the 620's, at least in the SFF box. I'll start by replacing the larger values and see if that resolves the issues. According to the 620 thread, the 220uf caps can cook, too, but I don't have any in stock to replace them all.
On to the pics.
