So you cleaned out. Where can you take all the stuff?
If you've got a bit of time on your hands, there are some better options that just bagging up everything for the trash. Particularly for pieces of electronic equipment, recycling is a better option than sending things to the dump.
Once or twice a year, my city hosts a recycling program and generally for free (there's a small fee for those ridiculously huge TV's and computer monitors), they will just take the items for recycling. It's worth asking your community about it!
Also, many tech stores have recycling or trade-in programs. Again, there's sometimes a small fee for huge TV's or computer monitors, but certain stores will give you a gift card equal to that fee.
Here's some links for a few of the major recycle programs:
