This board is functional (at least boots up into BIOS, I did not install yet an operating system). It is however sprinkled with KZG's, and because of my bad experience with them I would replace them preemptively.
We have:
4x 3300uF 6.3V UCC KZG (10mm)
24x 1000uF 6.3V UCC KZG (8mm)
6x 470uF 16V TK ATWY (8mm)
I plan to order some parts for other projects from Digikey, so I'd put everything in one order. The closest I could find there would be Nichicon HM for 3300 and 1000 uF and Panasonic FM for 470uF.
My question is, will a higher ESR (0.028 compared to 0.021 Ohm for 1000uF, 0.038 compared to 0.036 Ohm for 470uF) be detrimental on this board? Ripple current is higher in all cases.
I could order Nichicons HZ and HN from badcaps.net, but I want to avoid splitting the order.
There are also some small Evercon capacitors, 9 with 100uF/10V, one with 100uF/16V and one with 22uF/25V. Should I replace them while I am still at it, and with what kind of capacitors? There is no type written on them.
Here are some pictures: near the CPU, in addition to the 3300uF KZGs there are some Rubycon caps. The 1000uF are scattered everywhere, they can be easily distinguished from the TK's looking at the vent.
