I just found these pictures online and thought they were hella creative!

Props to college kids with alot of time on their hands

Mine is better...box AND duct tape

That puter on the wall is not bad. I was thinking about that same idea last week but I think it needs to be framed out (like a picture on the wall) and include the fans within the frame and cover it over with a piece of plexi glass. It would be just like a piece of artwork that hangs on the wall but it also functions as your pc. There would have to be some light work with it and several mod just use your imagination.
