Looks like someone applied a rather high voltage to those terminal blocks causing the cap to blow....are those for data or power supply input?
Reminds me of a recent incident where a not-too-bright gal at a company put 120volts onto the 12vdc bus of an AMX system, frying everything with a lot of magic smoke release! She even had the nerve to deny it when confronted with the cord someone(?) had made up, which she admitted she had plugged in! "No one told me it would do that!"
Total tally around $5,000 worth of equipment destroyed.
