HP Touchsmart 610 CPU Upgrade Disassembly And Maintenance All In One Test bench computer

I've had this computer for almost 10 years. Its sits on top my test bench so I can look at manuals and schematics. I like the compact all in one design. I prefer a full size/power computer to work on. Living near the beach and create havoc on electronics. Its rust the metal near the cooling fans and turns copper and solder green.
