Hi, I've recently purchased a Mac SE. I thought I would have to recap the logic board (I've never recapped anything before so was somewhat scared of that), but it looks to me as though the board might already be recapped. As you can see in the attached photo, all the caps are these new-looking blue ones (they look newer than the board), and they don't appear to be leaking at all.
The system boots off the old Quantum HD I installed in it, and for the most part works OK, except that no sound comes from the speaker. If I plug some speakers into the jack at the back, the sound works.
