The board can be rendered useless if the electrolyte is allowed to eat up the traces on the board, then chances of a full recovery are slim. Lifted solder pads are another thing (owing to age; on my last recap I only ate one solder pad. Good hing it was only going to ground).

I don't know much about the video out cards, however some cards are only compatible with very specific monitors because of the signals from the card can't be interpreted by non compatible displays.

For that matter I would like a VGA out card for my /30 preferably with a dual slot adaptor so I can also use my Ethernet card.
