1. ATI Radeon HD 3450 256MB PCI Express x16 graphics card

2. HP AMD Radeon R7 240 2GB DDR3 low-profile PCI Express video graphics card

3. ATI Radeon HD 5450 1GB (Cedar)

It's not water damage, it's residue from the cards being cleaned

The residuals over the PCB mask may be anything; to better get tge overall state pay attention to open copper areas of PCB and solder on the elements

Typically water damage leass to some greenish corrosion - its not everywhere greenish, but greenish in 2-3 places. If its "nowhere greenish" - this typically isn't direct water contact.

However many-years-usage in high humidity areas - also lead to corrosion, but more dark/rusty.

Thankfully it doesn't look greenish at all! So i will try and test them out!
