I wasn't identifying capacitors by their color and not sure where you assumed this from.

I think they might have misinterpreted my original post. I referenced the capacitors by color, because I marked them with different colors on the photo I posted. I simply wanted to have a way to reference which caps were which.

I think may have misunderstood that to think I was referencing the physical colors of the caps themselves.

I ended up placing an order with Digikey for polymer caps with a handful of different specs. I'm curious to measure them when I get them, especially to see what my ESR meter reports.

In the mean time, I removed all the 3300uF caps from the board and cleaned things up. It's ready for replacements.

I'm going to initially leave the 1500uF caps and test things to see if the board works. Depending on how that goes, I'll decide later if I want to also replace them.

I am interested to see what your results are with this. I recently picked up a small lot of scrap boards and one of them is a similar Socket 478 i845 chipset board with two ISA slots (not from DFI\ITOX though), and it definitely needs some caps replaced. The board looks to be in very very rough shape, but I'm hoping it isn't too far gone to repair. Either way, the price for the lot was low enough to make it worth trying to save it.

Also, I don't know if this is any help or not, but it looks like you can get DFI ITOX G4V620 boards (note: this one doesn't have a normal AGP slot) on Aliexpress right now and they are similar but have different caps on them... hard to tell what they are from the pictures. Can anyone tell what brand and series they are by the color?

Now for some blitting from the back buffer.
