I found a Macintosh Portable 5126 south side of London from the original owner. Got it back to the states today, put in a new battery and was surprised to find it works flawless (even the clock was set powered with 9v dated 9/94). Took it apart to remove the British invasion of dust bunnies and was even more surprised to find all the original caps are installed. Inspected them and see zero signs of leaks.

Now should I stick to the side of "Preventive Maintenance" and have the board recapped?

Or the side of the purest and leave it "Original as designed by Apple" and "Dont fix whats not broken"
