I take my non-ferrous to JS&S on the MD/DC border. Relatively recently they started taking desktop power supplies. They also buy whole desktops. But they don't take other lower-grade ewaste like floppy drives, computer fans, brown boards etc. There used to be ARCOA in Columbia that took all that stuff but I think it closed. Plus it wasn't very convenient for a variety of reasons.
There is also a Potomac Metals location in Beltsville but what they offer for anything ewaste is way too low.
So thanks for the leads, maybe I'll have better luck with them even though they are far from me.
