50W will let you power an HVAC extractor fan. I guess there may be motivations for some people to do this! (But, no, I want a silent PC, not a helicopter simulator!)
This isnt for your 'typical user'. Grab a couple of high spee delta's (I believe are over 1A), use 3 of those on a rad and you are pushing 40W with just 3 fans.
