I've an Asus P4P 800 that I had to partially recap a little over a year ago. I got it for free in 2019 and have used it to play some games. I looked at it one day, and it had a bulging cap so I replaced all that were that brand/voltage.

KZG are known to fail in storage. Had several cases of it.

A friend from work messaged me, he found an old pc in a thrift shop, figured I might like it and brought it home for me.
This was the picture he sent me:

Imagine my joy.

So in the last few days I took the machine apart, cleaned it and checked for visible damage.
Today I've started reassembling. Happy moment: we have output!

This makes perfect sense, since only the 3 1/2"drive and the screen are attached. All other parts, including hard drive and memory cards, are not connected.
If you want, I can post updates on the reassembly every now and then. Also open for suggestions on what to use it for.
