I wouldn't take items out of TechnoCycle (http://web.mit.edu/facilities/environmental/reuse.html#technocycle) bins on campus. Unless you're part of the MIT community, you could be cited for trespassing and/or theft. Better to do it legitimately through the reuse (http://web.mit.edu/workinggreen/reuse/reuse.html) mailing list (and associated programs). Lots of treasure gets posted on reuse for free.
