What stretches it is that a cheap desktop for that money will be very likely faster for it.
I looked into this years ago. The "DIY" options were around $60, but then you need to supply PSU and everything for the graphics card, and no enclosure.
Another thing people need to realize is that this will only allow an external display to use the desktop graphics card; the laptop screen will not be plugged into the GPU and thus the GPU won't be able to run games over the laptops screen. This is a "bring your laptop home and plug it into a desk setup" only.
