Does anyone know where i can get this capacitor or a same spec alternative?

The fuse is definitely blown, there are burn marks on the label "F00...". So you have to check all your Mosfets (and best, diodes too) if you don't want to burn your new fuse immediately (and repeatedly).So i ended up soldering one of these in, its a little tall but luckily just clears the HDD fan. And the iMac is back in business. All be it i have discovered that the ODD fan is now dead.

Next up I'll try my luck on the PSU fuse 🙄

Roger that, minimum amount of fuses I could buy was 10 so I'll start with that and cross my fingers 🤞The fuse is definitely blown, there are burn marks on the label "F00...".

Got another one,
Has anyone seen plastic insulation degrade like this:

I didn't even notice it as I wasn't replacing the fan and the cable was tucked in nicely as it should on this 2011 21.5"
When I powered on with the screen off to check the diagnostic LEDs I saw a flash and new something had instantly fried.
Turns out it blew a ferrite bead at L5710 and looks to have taken out its pad.

This was the area I saw the flash, however after examining the board further I noticed this:

C1603 and C1620 are gone, thinking it must have been related to the fan shorting?
Well done. Congratulations to your success!I carefully seperated the wires on the fan with scotch tape and hesitantly tested the fan in a 2010 and at least the fan is still working, although the corroded wire sheath is all the way down to the board solder joint and is brittle.
I'm thinking my best option for the fan is to cut the wires in the middle and heat shrink over both ends right up to the connection points except the twisted pair as it is fine, then solder the wires back together.
Hopefully I can find the 2 resistors and ferrite bead on AliExpress and get this going again.

Comments appreciated.
EDIT:
I think i got the correct components 🤞
