I mentioned it upthread and I don't want to look like I'm shilling but ... the Orange Pi zero board has 256M or 512M of ram, 4 cores, ethernet, wifi and all sorts of other stuff, for about $10. You have to provide storage though, and while it does have a graphics capability you need an expansion board (another $2) to use it.
