I tried this a couple years ago. My work got all new PC's and they were going to throw all these old Dell's in the trash. And they were still pretty decent PC's. So, I took as many as I could fit in my car. Probably like 8-9 desktops. I sold one of them on eBay and then decided that I didn't really feel like going through the trouble of selling them. They've sat in my basement ever since.
