Dell Monitor: 1905fp Rev A02 Capacitor Replacements

I've been holding onto my monitors for a long time. I don't see a matching bezel style in 24" and 19", let alone the same base style.
So when my 19" failed to turn on. I was sad. I thought it was the Display Port > DVI cable as when I switched the cable, the monitor lit up. Now I'm guess there was just the right conditions for the power to be 'ok'.
But I want to keep a record of what was in there and what I replaced. I wasn't able to get them all from JayCar as the are required to be low ESR.
470uF 35v x4
1000uF 25v x1
1000uF 10v x3
220uF 50v x2
22uF 50v x1
2.2uF 50v x1
10uF 50v x1
4.7uF 50v x1

I could only get the 22uF in a 63V package. I understand that a higher voltage in a capacitor is fine.
I couldn't replace the 2.2, 10 and 4.7 because I couldn't get them in low ESR.
I also had to skip the 220 as my click and collect order was one short (and had an extra 470). They look like they are related to the backlighting.

My friend has suggested https://www.digikey.com.au/ so I'll have to check that out in the future.
