Computer Recycling and Repurposing

Featured
Computers contain so many useful parts and components that can be recycled, reused and re-purposed, that it's a shame to simply throw them away. PC fans make great air filters, mother boards can become jewelry, hard drive platters beautifully turn into clocks and power supplies, and cd drives magically become home made secret safes and roulette wheels! So, think long and hard next time you find yourself thinking about throwing away a computer, and instead, take it apart and make one of the amazing projects below.
