Nice def. of a desk top PC
so for popular I went Urban and got:
Personal Computer. A highly flexible, powerful platform. Worth the price tag because you can do a whole lot more shit on it than you can ever do on a console such as typing up a document, image editing, music and video creation, and creating games. Will always be around when consoles systems rise and fall. The platform used to create all console games. The platform where all console games will eventually be emulated on.
I'll just stick to my trusty old PC for my gaming needs ;^D
but that's not quite right but fun, so from Websters:
