I don't remember the video specifically but in one episode of Scrapyard Wars, Linus was was looking for parts and came across a bunch of PSU units just kind of jumbled together in a box. He pointed out that it was hella dangerous, and that it could kill someone if something happened. Can someone smarter than me explain what's dangerous about that? Thanks in advance.

Capacitors are always dangerous, 
 Dont think you'd ever wanna touch a capacitor like that.
 
Also! everything could be dangerous. If you throw a potato hard enough at someone its dangerous too.

Lacking a smartness gauge I’ll try it anyway ‘cause I got hubris like that:
 
PSUs have capacitors.  They’re not unlike batteries.  The result is a pile of random PSUs could still be holding charge and it could be a lot of charge.
 
When I read the headline I imagined someone swinging a toaster around their head like a flail though so still yes.
