Okay, so I've got a Pentium 233 MMX Socket 7 build (parts from 97-98). I've replaced every single electrolytic capacitor at this point on the motherboard and soundcard (some leaking, some not). I have not yet touched my Riva 128ZX because the output is perfect and the tantalum caps seem fine visually. However, I've seen a lot of posts and videos of tantalum capacitors failing spectacularly and when they do, they typically fry a motherboard trace or something else adding to the damage. This ticking time-bomb is giving me anxiety and I'm finally motivated to address the potential problem.
It's been a little difficult to identify the exact specifics of these capacitors, but I'm thinking the 10uF are most likely these...

However, I'd like to replace them with aluminum polymer caps to avoid future fireworks. These look like they should physically work, but I'm worried they are too low ESR.

Tantalum part shows an ESR of 1.4 ohm and the polymer shows an ESR of 0.04 ohm. Ripple on tantalum is 0.3 A and polymer shows 1.6 A.
Will these differences matter for this application? Has anyone gone down this path before? Any suggestions?
Thanks!
