Have some old Powermac G4 and G5 computers laying around with failing parts? Gut them, stack them and use them for straightening up your cluttered office. The computers are held together with 12 strong paper clamps, then secured with zip ties to a piece of plywood on the bottom and some eyelet screws in the wall at the top. Dead computers can still be useful for holding your cds, dvds, books and extra cables. Plus, as long as they stay secured to the wall, they’ll never crash.
