I‘m not sure about the $30. but look at the Fujitsu Futro S740. They can be had for about $50 with 8gb of ram and an included ssd, have support for dual 4K monitors and so on. No WiFi out of the box, but they do have a second m.2 that can be used with a cheap WiFi card if that is what you need (or you could install a second ssd).
