Suspicious capacitors on a PicassoII

[Lo]

Its been a while since I repaired stuff on a component level (hah! its all modular now :/) ,  My Picasso II board has several capacitors blue in color, with um, "wrinkled" tops with a touch of white powder (I suspect salt, live near the beach)  Would it behoove me to change out these guys or chalk it up to cosmetics?  OH, hmm.. the PII is probably a multi-layered board,...yikes.

No, I did not turn it on yet

If it was my board, I'd replace them!  From what I've heard, capacitors like you described are about to pop any time, and that electrolyte on the board can be as bad as a leaking battery...  For a while a year or two ago, there were lots of reports of all kinds of PC motherboards with this problem, due to someone stealing the formula for the stuff inside but getting it wrong
