    By mmn

    When doing your dumpster diving tours/raids, it's not unusual to find monitors lying around. Fortunately enough those huge old CRTs are mostly long gone as people want to use their desktop space to store other meaningless crap such as papers and forgotten bits of food. And coffee mugs. So …
