1st time scrapper here! I have a special needs son who likes to unscrew things which means I find myself with some dismantled electronics. As such, I am learning to scrap. I don't remember where these came from. I think the 1st one is of middle grade as it has a small amount of gold pins, nice components and very little junk, so it seems. The second must be of higher grade as it has more gold (I removed several heat shields). For both I am asking the grade and type and if it would be better to remove the pins and and chips or sell as is.

Top is a cd rom board, and the bottom is high perf.

Thank you, that is as helpful as it is concise
