What should I do with all the e-waste piled up in my house?

You can take it to the recycler. I am not sure if he will accept all those but at least some of them will be surely off your back. A recycler I know takes computer screens, UPS etc but not defective keyboards or mouse. For removal of any other trash item I call the Junk It trash removal service. I have also rented a dumpster from them. Find a recycler near your area and get rid of all those e waste.
