I blow dust out every 6 months and I noticed that my ASUS NCT-D Server motherboard had blown one of the 6.3v 1500uF KZG cap. (marked in red)

The motherboard however works fine.

Other caps are OK.

I made this list off all caps, please suggest what to replace. Should I just replace the blown cap and all 6.3v 1500uF?

The yellow caps have no brand. What they are?

P.S. I have Peak ESR70, but the caps can't be measured in circuit, gives me leaky, 0.00mΩ readings

The original Yellow caps are polymer, is it needed to replace them given the 10 years, since they do not bulge how to test them?
Desoldering and measuring is the only way?

16pcs 2.5v 820uf FUJITSU -> Panasonic Solid Capacitor, OS-CON, SEPC Series farnell.com order code 2354628
8pcs 16v 330uf FUJITSU -> WCAP-PT5H Series farnell.com order code 2466595

When replacing caps other than the value and voltage, type is sometimes important in mobo's but still it might work.
Just make sure what you replace with are of low ESR types.
