An ASUS M2N68-AM PLUS motherboard is being used to manage environmental controls in a range of greenhouses. It's a pretty good board for that purpose because it has a parallel (printer) port, serial port, PCI and PCIe slots, gigabit ethernet, can use unbuffered ECC RAM, etc.
The caps for the CPU VRM are polymers, but there are UCC KZG caps on the board. None appear to be bulging and leaking, and the board seems to work fine at this time. Should I preemptively recap the KZG's? Or leave it alone unless it starts misbehaving? I have a blue ESR meter, and a DE-5000 LCR meter, but feel that if I have to pull the caps to test them then I might as well just replace them. What do you think?
