Title:

iMac G4 won't boot, fan twitches

Text:

Alright guys, so I'm having some troubles with an old flowerpot iMac. About a month ago I knocked a glass of water on the desk where the computer is sitting. There was no splash to speak of, the water just spilled around the base of the  iMac. I immediately pulled the plug, but didn't feel like doing much more, as it was 3AM. Anyway, I left it like that for over a week before plugging it back in and trying to turn it on.  Well, it didn't boot. I was kind of surprised because it was a relatively small amount of water and I didn't think it would get inside from under the base.

Now, I'm far from an expert, so I did some Googling and tried resetting the PRAM on the switch on the motherboard to no avail. I also checked the CMOS battery, which seems to still have power in it. Today, I decided to take apart the iMac for the heck of it. I cleaned it to the best of my capabilities and reseated the RAM. Tried turning it on while it was taken apart and noticed that the fan twitches when I plug it into an outlet. Nothing happens when pressing the power button. I don't see any blown capacitors on the motherboard or psu. I tried turning it on without the HDD and optical drive connected, just in case, and again the fan twitched when I plugged it in.

Any help is appreciated!

Edit: Here's the base and both sides of the motherboard. I don't see anything around the vent holes, save for a bit of dust.

Edit 2: Alright, so the photos got scaled down while uploading. Here's a Google Photos album with the full-size images: https://photos.app.goo.gl/TiF1wUOPPoC3OIVs1
