If he wants to use it for gaming over steam link, he'll need a graphical interface. I use a PC this way as well: headless most of the time, although realistically you'll want to use a monitor once in a while to configure steam and figure out gfx issues (and in my case, if it boots it defaults to a 640x480 display, which I need to fix by attaching an actual monitor, I'm sure there's a way around it, but meh).
