New to Scrappig and loving it-Great find on my first night, but need advice

Not so sure about the copier or scanners but I can shed some light on the towers. Towers are like your pan of gold when panning for gold. Sometimes you find a good nugget. Open up the tower. Remove and separate individual components. Drives, power units, memory cards (ram), once these are removed, work on the heat sink. Remove heat sink and fan and underneath you'll find the goodies, this is where you'll find your CPU. Usually a square shaped chip with gold pins and if you're lucky the back may be gold as well. Then remove your mother board. Sometimes individual boards may also be connected to your mother board, these contain gold too. Everything in the tower is worth something. Keep reading on the forum and you'll find ample information. As for selling stick to three and you'll be perfectly fine. Easy Recycles, Boardsort, and Cash for electronic Scrap. Enjoy the fever and welcome to the game.
