Dell Optiplex 790 smokers edition cleanup - this is disgusting!

This is one of the worst desktop computer cleaning jobs we've done. This was given to us after providing a new Dell Optiplex 5060. This old Dell 790 was cased in 7 years of dirt, grime and nicotine.
The grime was beyond a normal air blower clean up so we completely disassembled for cleaning.
Due to the decent 3.1Ghz CPU, we added some additional RAM and our next steps for this unit is to replace the HDD with an SSD. Even with the hard drive it still performs well so this will be donated to our local church for use.
